As we round the corner on 2021, the microelectronics industry continues to face a severe talent crisis. With more than 34,000 jobs remaining unfilled at SEMI member companies in the United States alone, everyone is competing for the same talent pool. While the semiconductor shortage has received extensive media coverage, a critical talent shortage deserves equal attention. One way to address the talent shortage is to hold the line. Meaning, in addition to recruiting more diverse talent into the chip industry, we must retain the quality workforce we have. I believe that a key component of a diversity, equity and inclusion program must be retention. At Edwards, we feel so strongly about this that we have made retention a key part of our Diversity, Equity and Inclusion program – even changing the acronym to DEIR (pronounced DEER; diversity, equity, inclusion and retention) for emphasis. There are three overarching approaches we can take to promoting diversity-focused retention:Investment in on-boarding practices that allow time to hire appropriately and ensure a diverse pool of qualified candidatesEmbedded programming and policies that are learning and development (L D) based including career planning, succession planning, unconscious bias training, employee resource groups (ERG) and mentoringCorporate culture that respects employees through a healthy work life balance and promotes the well-being of society and the planetThis is a very important conversation. I asked Lubab Sheet-Davis, vice president of Strategy Innovation in the Office of the CTO at Lam Research, and Emerald Greig, executive vice president Americas at SurplusGLOBAL USA, to share their considerable experience and insight related to retention and DEI. Following is an excerpt from our conversation, which has been edited for clarity and brevity.Balaguer: In the context of DEI, why is employee retention so important?Sheet-Davis: In my view, there is a strong correlation between inclusion and retention. If people feel that their voices and perspectives are valued, they are more likely not only to stay, but also to perform at a higher level. Driving both inclusion and retention is having a seat at the table, having your voice heard, respectful treatment and fair opportunity. Retention is a core component of our inclusion and diversity strategy, which involves increasing representation by building a pipeline of diverse candidates, recruiting and retaining, fostering an inclusive culture (which supports retention) and open communication to share our progress.Balaguer: What role does data play in the drive to increase retention?Greig: Ours is a data-driven industry and I am surprised that we have not let the statistics drive us into action sooner. Clearly, diversity, equity, inclusion and retention all affect the bottom line. Millennials and Gen Zs already leave faster than any other generational group. The turnover rate in the tech industry averages around 13% with stays around 2-3 years.The cost to hire, train and integrate someone into a company is far more expensive than having a DEIR program in place to keep them. The Society for Human Resource Management (SHRM) reported that, on average, it costs a company 6 to 9 months of an employee's salary to replace them (which includes the costs of hiring, onboarding and training, L D and time to fill the role). For an employee making $60,000 per year, that comes out to $30,000 to $45,000 in recruiting and training costs.Sheet-Davis: Yes, which gives us all the more reason to move quickly! Given how central DEIR is to innovation, and that the challenges and opportunities facing our industry are bigger now than ever before, I believe we should be addressing DEIR with the same vigor that we address Moore’s Law.I worry if we keep saying DEIR will take time, it will take time. Granted many DEIR issues are cultural and culture is hard to change. However, this industry has demonstrated the capability to drive breakthroughs and to do so quickly. Let’s focus on DEIR with urgency while also ensuring the progress is sustainable.Balaguer: There is no doubt we need to move with a sense of urgency. I think a good way to keep the pedal to the metal is to create a DEIR roadmap that tracks our progress on multiple programs and helps us be accountable and stay focused. Meaningful retention strategies begin with solid diversity-focused hiring strategies.Balaguer: How does corporate culture inform retention?Greig: Let’s not forget: Employees, especially millennials, are looking for a corporate culture that demonstrates social responsibility as well as leadership and career development. In a recent study, 65% of employees said positive corporate culture has encouraged them to stay with their company. In fact, companies with strong cultures have seen a four-fold increase in revenue growth.We have raised a generation that strongly believes in being accepting of others and embraces equity and inclusion in their daily lives. They expect their employer to have this as part of their DNA. They believe in science, climate change, recycling, conservation, and similar sustainability issues and they want to know that they are making or doing something that makes the world a better place. If tech companies cannot convince millennials and Gen Z's that the companies are socially responsible and are doing all they can to embrace DEIR as part of their company culture, then the millennials will go elsewhere. Balaguer: How can employee resource groups be a building block for retention?Sheet-Davis: We support employee resource groups that are voluntary, employee-led and coalesce around demographic factors such as gender, ethnicity, sexual orientation or generation. Each has an executive sponsor, budget, plans and leadership structure. ERGs support inclusion by creating a sense of belonging, building comradery, and providing a safe space to raise awareness and help educate the rest of the company through a number of activities such as community service, holiday celebrations, guest speakers, networking, training courses and more. I serve as the executive sponsor of our Women@Fremont group, which is focused on accelerating the advancement of women in their early to mid-career at Lam’s headquarters. I know ERG members genuinely value the company’s support.Balaguer: What can we do during the hiring process to lay a strong foundation for employee retention?Greig: I believe that the work we do at the front end in terms of hiring practices are one of the main reasons we have a low turnover rate at SurplusGLOBAL. We have a policy to have three interviews for each candidate. Not three different people, but bring them in three times. Additionally, we have a 90-day trial and review period to make sure there is a good fit for both parties. Investing time up front ensures the right hire and the small size of our company allows us to know our employees. We can be nimble and quickly respond to employee needs as they arise.Balaguer: In what ways do you think mentoring can help improve retention?Sheet-Davis: Another aspect of building a more inclusive culture, and hence promoting retention, is through mentoring programs. Mentorship supports an employee’s development, growth and career planning. It’s a great way to get to know people, understand their ambitions and support their development. Hopefully, it results in sponsorship because that is what helps drive career advancement. Ultimately, I want to advocate for those that I mentor.Balaguer: At Edwards, we are refreshing mentoring as part of our DEIR program. I see mentoring as a program that can support employee retention in multiple ways including career planning, professional development, succession planning and promoting inclusivity. Encouraging and empowering personal development is key in growing a productive workforce and mentoring does all these things. Often overlooked is the fact that mentoring is a benefit to both the mentor and the mentee. I have personally mentored several young professionals at Edwards, and I can attest that I have learned as much from them as they have from me. Mentoring is definitely a two-way street.Balaguer: What’s your message to our readers about retention as an element of diversity, equity and inclusion?Greig: I am excited to see DEIR and especially, retention, gaining traction. The semiconductor industry has always tended to have a cyclical rhythm to it. A generation of potential employees have grown up witnessing the fallout from periodic down cycles and the inevitable reductions in workforce. I think there is an element of rebranding we need to do in this area to support our retention efforts. Sheet-Davis: If we only focus on recruiting and not retention, we tread water. Consistent with any other successful business strategy, a holistic integrated approach to DEIR that is prioritized, resourced and sustained over time is key. Balaguer: We all agree that retention is a key component in the war for talent. While this conversation has been more wide-ranging than we can share with our readers, the prime takeaways have focused on these elements: Follow the data. Execute with a sense of urgency. Hire right. Work hard on inclusionary programming such as ERGs, mentoring and sponsorship. Build a genuine corporate social responsibility program. Retention will result.Many thanks to Lubab Sheet-Davis and Emerald Greig. As always, comments, questions and suggestions are welcome. We can be reached at [email protected], [email protected] and [email protected]. I invite our readers to join the conversation, as well as review the recently released SEMI Foundation DEI Roadmap and Toolkit.Scott Balaguer is Vice President and General Manager, Semiconductor Division at Edwards Vacuum LLC and Chairman of the SEMI North America Advisory Board.

The state of Penang, nestled along the northwest coast of Peninsular Malaysia, needs no introduction in the global electronics manufacturing sector. Despite its diminutive stature with just over 1,000 square kilometers of land area and a 1.8 million-strong population, Penang commanded an estimated 5% of global semiconductor exports in 2019, according to data compiled from the Department of Statistics Malaysia (DOSM) and UN Comtrade. The State’s transformation, from a traditional seaport economy into the Silicon Valley of the East, began in the 1970s, when the establishment of Malaysia’s first free trade zone in the State drew key investments from eight Multinational Corporations (MNCs). These pioneering investors – Intel Corporation, Hewlett Packard (now Keysight Technologies and Agilent Technologies), Robert Bosch, AMD, Litronix (now Osram Opto Semiconductors), Hitachi (now Renesas), Clarion and National Semiconductor[1] – sparked the development of a robust ecosystem of ancillary industries, which formed a foundation for the State’s rise as a prominent, offsite manufacturing hub. Today, Penang houses more than 350 MNCs that are supported by over 3,000 manufacturing-related SMEs. As Penang flourished as a vibrant, regional E E manufacturing hub, the local talent pool steadily accumulated a wealth of business intelligence and technical experience, enabling the robust supply chain to evolve in tandem with technology megatrends. This, in turn, enabled the State to focus on pursuing investments that have propelled the industry up the value chain, away from its beginnings as a low-cost manufacturing hub. Consequently, Penang has seen a proliferation of upstream technology-related investments in high value-added functions in recent years, ranging from research and development (R D), design and knowledge-based solutions, and downstream advanced manufacturing and testing to global business service (GBS) and Centre of Excellence (CoE) activities. Penang’s growing significance in the global E E value chain is demonstrated by its steady and resilient export performance in recent years. From 2014 to 2019, the State’s E E exports grew at a compounded annual rate (CAGR) of 12% to reach RM210 billion (US$51 billion). It has emerged as a hub for professional, scientific and controlling instruments (including medical technology), with exports of these products growing at a 5-year CAGR of 15% to reach RM23 billion (US$6 billion) in 2019. E E products, alongside professional, scientific and controlling instruments, collectively contributed between 77% and 82% of Penang’s total annual exports since 2014, and accounted for 50% of Malaysia’s exports in these two segments during the period. More impressively, despite the disruptions from the COVID-19 pandemic, Penang’s total exports continued to rise in 2020, growing 7% year-on-year to RM310 billion (US$75 billion), and a further 14% year-on-year in January and February 2021, driven by strong global demand for semiconductors. Shaping up as the destination of choice for advanced manufacturing investments As part of efforts to move Penang’s industry up the value chain, the State government has placed emphasis on attracting companies with strong commitments in implementing Industry 4.0 and sustainable investing. These efforts have yielded positive results, with the state having gained traction as a hub for advanced manufacturing investments. This is evidenced by the rising trend in investments per new job creation, which saw a six-fold jump from 2012 to 2020, as well as the number of global heavyweights announcing new investments as well as expansions of existing facilities in the State in 2019 and 2020. Penang attracted RM31 billion (US$7.5 billion) in approved direct manufacturing investment inflows in 2019 and 2020, 88% of which involved investments into the E E, equipment and medical technology industries. Prominent new investments included those from Lam Research, Bosch Group, Ultra Clean Holdings, Dexcom as well as Smith+Nephew. Together with planned expansions by a number of existing MNCs in Penang, these new investments, which are on track to commence operations between 2021 and 2023, are poised to bring Penang’s industry to greater heights and further integrate the State into the global value chain. Recent Notable Direct Manufacturing Investments in Penang Source: InvestPenang and respective companies Penang’s conducive business environment nurtures successful homegrown technology companies Penang’s conducive business environment has not only proven successful in attracting foreign direct investments (FDIs), but also successfully nurtured local E E success stories of locally employed engineers turned technopreneurs, who have founded and built companies that have successfully grown to become internationally renowned in their own right. These homegrown E E companies play crucial roles in the ecosystem, particularly in the areas of automated test equipment (ATE), automation, outsourced semiconductor assembly and testing (OSAT) services, electronics manufacturing services (EMS), precision engineering and tooling. The past five years have also seen the emergence of young, fast-growing Penang-based companies such as Experior, Oppstar Technology and Skyechip, which provide IC design and IC test design services to MNC clients globally. Public-private partnerships cultivate Penang’s talent development roadmap The state is cognisant that the development of a robust and skilled talent pool is imperative to support the growth of strategic industries in Penang. Strong public-private partnerships with concerted efforts in supporting talent development are key to Penang’s continued success. Toward this end, the State government has backed Penang Skills Development Centre’s (PSDC) industry-led training and education efforts, which have helped train over 200,000 of workers to support the industry’s needs since 1989. The State has also coordinated collaboration for industries to provide input to local institutions of higher learning on the relevance of the institutions’ courses, and rallied the industry to support State-run scholarships (Penang Future Foundation) and STEM initiatives. Holistic initiatives to make Penang a world-class investment destination for global frontier companies The dynamics of the global value chain, especially for the technology sector, have evolved rapidly since 2018, particularly amid the complex confluence of trade protectionism, COVID-19 pandemic-driven issues and disruptive technologies. The State government believes that strong, geographically localised industry clusters could help companies mitigate the risks of supply chain disruptions, in addition to improving companies’ time-to-market at a lower cost. To further increase Penang’s attractiveness for high quality investments, the State is focusing on three key strategies: Extending its competitive edge in advanced manufacturing, further strengthening Penang’s industry clusters, which include expediting SMEs’ Industry 4.0 transformation journey, and nurturing more homegrown companies to penetrate the global supply chain Embarking on a continuous drive to develop and recruit talent to the State, as well as cultivate the younger generation’s interest in STEM Enhancing Penang’s liveability with a strong focus on making Penang a smart and green city The State government is committed to continue developing Penang in a holistic manner, with the aim of creating a vibrant business and investment destination with a robust and sustainable economy and high standard of living, creating a conducive environment to “work, live, learn, play and invest.” About InvestPenang InvestPenang is the Penang State Government’s principal agency for promotion of investment. Its objectives are to develop and sustain Penang’s economy by enhancing and continuously supporting business activities in the State through foreign and local investments, including spawning viable new growth centres. To realize its objectives, InvestPenang also runs initiatives like the SMART Penang Centre (providing assistance to SMEs), Penang CAT Centre (for talent attraction and retention) and i4.0 seed fund (a catalyst for the start-up ecosystem). For more information, contact [email protected]. InvestPenang also works closely with various industry associations, including SEMI, to promote Penang’s supply chain and E E ecosystem. InvestPenang is delighted to have collaborated with SEMI on numerous occasions since 2015 and endeavours to sustain the partnership in the years to come, including for the SEMICON SEA 2022 exposition to be held in Penang.

What does it mean to identify as LGBTQIA+ in the semiconductor industry? It’s an interesting question to ask, but a difficult one to answer. Because we live in a world in which cisgender heteronormity is assumed, it’s possible to self-identify as LGBTQIA+ without sharing that information publicly. Coworkers and managers might not even realize that their colleague or employee is gay, lesbian, transgender, non-binary or other. Unlike other minorities, notably people of color, LGBTQIA+ people may choose to keep their identities invisible.As I began outreach for this article, I recognized that some people might not want to expose a potential vulnerability to both their co-workers and a broader global audience of SEMI members, so I tried to make them feel more comfortable. I told them I’m a lesbian. I said that I’d send content for their review before publishing. But I quickly discovered that wasn’t enough, despite sweeping cultural and legal advances around LGBTQIA+ attitudes and identity. According to a 2020 Gallup Poll, 5.6% of U.S. adults now identify as LGBTQIA+, up from 4.5% just three years ago. In 2004, Massachusetts became the first U.S. state to legalize same-sex marriage, and in 2015, the U.S. Supreme Court made same-sex marriage legal in all 50 states. The semiconductor industry has been historically conservative. The times, however, are changing. Large chip companies such as AMD, Intel and Lam Research actively support diversity and inclusion efforts across minority groups, including LGBTQIA+, and that’s a good thing, but is it enough? And if not, what actions can SEMI members take to help LGBTQIA+ people in semiconductors feel safe enough to choose visibility?According to Antoinette Hamilton, global head of Inclusion and Diversity at Lam Research, more than 46% of LGBTQIA+ employees in the industry aren’t out in the workplace. That tells us there’s still work to be done, a challenge that Lam is embracing. With its Pride employee resource group (ERG) leading the way, partnerships with organizations such as PFLAG and Out Equal, and recruitment efforts made through organizations such as Out in Science, Technology, Engineering, and Mathematics (oSTEM), Lam has earned a score of 100 on the Human Rights Campaign Foundation’s Corporate Equality Index and was named one of the Best Places to Work for LGBTQ Equality.“At Lam, we understand the importance of empowering employees to bring their authentic self to work,” says Hamilton. “We believe when employees feel valued and included, each person can reach their full potential.”Back in 1992 when Intel paid to relocate Judi Goldstein, her partner and their son from New Jersey to Oregon, mainstream cultural attitudes toward gays and lesbians were very different. According to a June 1992 Gallup poll, only 48% of Americans thought that “gay or lesbian relations between consenting adults should be legal,” with 44% saying they should be illegal. A May 2020 Gallup poll recorded a dramatic shift in attitudes, with 72% affirming the legality of same-sex relations and only 24% opposed.By the late 1990s, Intel had extended domestic partner benefits to same-sex couples. “I registered my partner – now my wife – and our son, and realized that from then on, my whole family would have health insurance through Intel,” says Goldstein, who identifies as a gay woman and uses she/her pronouns. “Both relocating my family and providing family health coverage solidified my attachment to Intel, which was way ahead of other companies at the time.”By 1995, Goldstein became one of the first members of IGLOBE, Intel’s ERG for LGBTQ+ employees. Since that time, she’s observed further progress at Intel, first with the addition of gender identity and expression to Intel’s anti-harassment policy, and later with the inclusion of gender-neutral bathrooms at all major US sites. And advancement didn’t stop there.“We now have international IGLOBE chapters, a celebration of Pride Month in June, company support for the Equality Act and other legislation, a provision for transgender health benefits, and the launch of Self-ID efforts in 2017,” she says.From her start as software engineer more than 32 years ago to her current positions as director of the Open Source Audio and Security Engineering teams, Goldstein has played an instrumental role pioneering new technologies and mentoring other engineers at Intel – in addition to serving as a role model for LGBTQIA+ employees coming through the ranks. Now a grandmother with a five-year-old granddaughter, Goldstein lives in Oregon with her wife of more than 30 and two dogs. Location, Location, LocationAs social animals, we tend to value safe and welcoming places to live. When you’re LGBTQIA+, this may mean moving to an urban area that is more likely to embrace diverse orientations and cultures.After getting his master’s in astrophysics, Chuck Chung had a decision to make. Remain in the same field, which would limit his options on where to live, or get a doctorate in engineering, which would expand them.“In the ‘90s when I was making this choice, things were very different, and I knew that where I worked and lived would have a huge impact on how open I could be,” said Chung. “While I would have loved a career in astrophysics, I realized that engineering would be a more practical choice because I was more likely to find work in a city.”Both personally and professionally, engineering has proved a good choice for Chung. He’s lived in San Francisco and Silicon Valley for the past 18 years, where being out in the workplace is rarely an issue. “I compartmentalize my personal and professional lives when necessary, such as when business colleagues who are overseas talk about their families in casual conversation. Most of the time, though, my identity as a gay man is a non-issue, and I work for a company that really cares.”From his pioneering work in MEMS and genetic sequencing to his current focus on the next generation of microarchitectures at IBM, Chung has long thrived. Now, with a new book on MEMS Product Development – co-authored with two other Ph.D.’s, Alissa Fitzgerald and Carolyn White of A.M. Fitzgerald Associates – the best days of Chung’s career may still be ahead of him. He lives in the Bay area with his husband and their two children.Kunal Garg’s identity didn’t influence his career choices because when he started in semiconductors, he wasn’t out to himself or others. A few years into his engineering career at his former company, Garg realized his identity as a gay man at a time when the national discussion about same-sex marriage was at its apex – leading to some uncomfortable situations at work. “As some of my colleagues and managers openly debated same-sex marriage, they seemed oblivious to the fact that there were LGBTQIA+ people at work,” says Garg. “I knew then that I wanted to steer such conversations in a way that would feel safe and inviting for people like me, who work in this industry while being true to their identities.”Once he’d come out to his family and friends, particularly after he married his husband, Garg wasn’t willing to stay silent at work. “Although it took courage and internal struggle to come out to colleagues, my identity as a gay man wasn’t something I wanted to hide or deny anymore,” he says. “Some people laughed when I mentioned my ‘husband.’ The idea that their colleague, an engineer, an Indian immigrant, a man, could be gay and married to another guy was so foreign, it was almost laughable. Luckily, this didn’t stop me from being myself at work, and over time, these types of conversations became very rare.”Nonetheless, Garg looked around for ways to be part of the LGBTQIA+ engineering community. When he moved to AMD in Austin, he wanted to start with a clean slate. “When my manager called to invite me to join his team at AMD, I casually brought up the fact that my husband was going to need to start looking for a new job in Austin. And, very casually, he asked me what my husband did for a living, and we went on to discuss how Austin would be a great city for us to live in,” says Garg. “The fact that this was such a normal conversation was a big factor in my decision to join AMD.”Soon after starting as a design engineer at AMD, Garg found that LGBTQIA+ engineering community for which he’d been searching. He joined AMD’s Pride ERG, a group that he now chairs. “Being a part of this ERG has been transformational for me on a personal level and has allowed me to connect with my fellow engineers and people in my industry, beyond our mutual love for science and technology.”Become a change agentWhile some chip companies actively promote inclusion and diversity of LGBTQIA+ employees, others still have a long way to go. SEMI and the SEMI Foundation are uniquely positioned to help advance LGBTQIA+ equity issues in the microelectronics industry. "The SEMI Foundation is committed to promoting Diversity, Equity, and Inclusion (DEI) in our industry for the benefit of our workers and our member companies,” says Shari Liss, executive director of the SEMI Foundation. “We are designing programs for human resources departments, company leaders, and DEI allies to make the case for stronger DEI practices that will attract, retain, and promote LGBTQIA+ individuals and other underrepresented groups in our industry. We will soon publish SEMI's Roadmap to Diversity, Equity, and Inclusion and DEI Toolkit, which will contain tools to help companies strengthen their workplace cultures so everyone – including those that identify as LGBTQIA+ – will feel welcome, and will be able to do their best work."“If we want to truly see the semiconductor industry flourish on a global level, we need to push for equitable treatment of LGBTQIA+ and other minority employees,” says Garg. “SEMI can help by educating industry leaders, especially in countries outside North America and Europe, on how diversity and inclusion through policy are vital to their sustained productivity. These workshops and trainings should be data-driven to encourage companies to hire more LGBTQIA+ employees and to create policies that promote the well-being of all employees.”It’s not just at the company level or the industry association level that matters. Just as individuals are necessary change agents in proliferating greater equity among women and people of color, they’re also needed as allies of LGBTQIA+ people.“Like so many of us, I’d love to wave a magic wand to end discrimination based on gender identity or sexual orientation, but like any cultural shift, most change comes in small steps, not in giant leaps,” said Karen Lightman, executive director, Metro21: Smart Cities Institute – Carnegie Mellon University. “Fortunately, it’s easy to help make those small steps by becoming an ally to LGBTQIA+-identified people. When you see an injustice, don’t stay silent. Use your voice. There’s transformative power in that act alone. As one step, I’ve started using my pronouns when I introduce myself and now include them in my digital signature. It’s an easy way for me to express that I am an ally to LGBTQIA+-identified people.”Help us make the change. Use your voice. Get involved. Encourage your company to advocate for LGBTQIA+ inclusion and diversity.Maria Vetrano, principal of Vetrano Communications, is a PR consultant at SEMI Foundation.

The pandemic has taught us that diversity in the supply chain is more critical than ever. We need to be reliant on all resources available to us and seize opportunities where we can. With 2021 coming in hot with chip shortages across the world, there is a race to increase production yields despite traditional supply chains tapping out from a capacity standpoint. Solutions to these technology and supply chain problems require all hands-on deck including the smartest people in the world wherever, whoever, and however they are. Unfortunately, a quick look at the semiconductor supply chain reveals that for whatever reason, too many diverse owned suppliers are nowhere to be found. So, what does this mean for the semiconductor industry? It’s as if we’re working with one hand tied behind our back. Supplier DiversitySupplier Diversity is a strategy that drives the inclusion of diverse-owned businesses in the procurement of goods and services within an organization. Diverse groups vary globally in accordance with local laws but often include underrepresented groups such as women and local in-country minorities. Diverse companies are currently certified by being at least 51% owned, operated, and controlled by diverse individuals. Supplier diversity does not include lowering bidding standards or awarding business based on diversity status. Diversity done right increases ideas and competition.By diversifying the supply chain, we can expect to see an influx of innovation to improve our processes through competition. Diverse companies entering new markets bring unique perspectives and can often focus on R D problems large multinationals overlook. Engaging in the semiconductor industry allows local businesses to learn from what already exists in the market and offer new ideas that were not considered before. Furthermore, local businesses have more flexibility to create custom solutions for the process.New diverse suppliers also mean additional capacity to supplement the already taxed supply base. If your current suppliers are telling you they’re full, it might be time to branch out. Don’t assume that diverse suppliers are incapable of scale. There are many examples of multi-billion-dollar companies that are certified-diverse bringing world class scale, solutions, and capability to existing semiconductor supply chains. From one off prototyping to large scale manufacturing, diverse suppliers bring multiple skill sets. In addition to innovation and capacity building, expanding diverse suppliers has multiple other benefits to consider:Government tax and contract incentives exist for supply chains with certified diverse content2020 increased public awareness of diversity and Corporate Social Responsibility (CSR) initiatives. Expanding these programs is in line with stakeholder expectations.Flexibility of a privately held company with excellent customer service, often with less bureaucracy of a publicly traded companyTake ActionIf you’re seeing the gap between supply (chain) and demand, there’s plenty you can do about it. If you are a diverse owned company in an adjacent high precision manufacturing space, consider joining the semiconductor industry. You can reach out to your certifying NGO to find out more about our industry (SEMI is reaching out to them!).If you’re a company looking to cast a wider and more inclusive global net in your bidding process, you’ve got options as well. Start by making an intentional effort to start your own supplier diversity program. Scrub your existing supply chain and you may be surprised to find you’re already working with some high performing diverse suppliers. Maintain high standards and fair bidding while proactively including diverse suppliers in your opportunities – they can compete and win the business.The Manufacturing Ownership Diversity In 2018, SEMI members Applied Materials, Lam Research, TEL, and Intel approached SEMI with the idea of forming a special interest group that would work to increase the available diverse suppliers within the semiconductor industry. This led to the creation of the SEMI Manufacturing Ownership Diversity (MOD). The SEMI MOD working group is comprised of chip manufacturers, OEMs, component suppliers and NGOs working to develop a common standard to define supplier diversity within the industry and provide best practices. While all companies are welcome and needed to bring their best, we’d like to focus on the opportunities for diverse suppliers. An early participant is Heateflex, a minority owned business until 2019 which was brought onboard by Intel and Applied Materials.It’s time our industry takes a proactive approach to finding, inviting, and cultivating every able supply chain partner, including those that are diverse owned. We must make it clear that we are open for business to diverse companies – problem solvers needed! A more diverse supply chain will not only address the capacity issue, but it can also lead to improving innovation and cost savings, enable companies to qualify for new opportunities, and connect businesses with common corporate values.Our message is simple: Join us! The semiconductor industry is “open for business” and calling all diverse suppliers which bring a competitive advantage to the table. For more information about the MOD, visit us under the SEMI Foundation at the SEMI Manufacturing Ownership Diversity (MOD). The MOD is planning a virtual panel discussion on May 11, 2021 to introduce supplier diversity concepts and best practices in the semiconductor industry. Look for more information on the MOD web page.Beckett Tracy, Commercial Group Lead, Intel Corporation; Carlos D.

At the SEMI Foundation, we’re taking steps to support a big, audacious goal – achieving gender parity in the microelectronics industry. Dating to its roots at Bell Labs, Fairchild Semiconductor, and Intel in the late 1950s and 1960s, the semiconductor industry was pioneered by men at a time when far fewer women were in the workforce. While women have made major workforce gains since those early days, we’re still far from achieving anything close to an equitable representation of women. According to the U.S. Bureau of Labor, only 11.8% of electrical and electronics engineers – and just 8.7% of mechanical engineers – are women. What’s more, research from the American Association of University Women (AAUW), a non-profit that champions equity for women and girls through advocacy, education, and research, tells us that women drop out of engineering careers more steadily and quickly than men. According to AAUW research, just 30% of women working in engineering are still in the field after 20 years compared to 35% of men. By the time women have been in the field for 30-34 years, that number falls to 19% – while it increases to 39% of men among the same cohort. The small number of women in engineering careers and the fewer still who stay in engineering long term illustrate the troubling gender disparities in the industry. Even with these low numbers, however, there are still women who have managed to not just stay in the industry, but to thrive and lead within it. I talked with four of these women about their professional journeys and how they believe women can be best supported in careers in our industry. The AAUW research report Solving the Equation: The Variables for Women’s Success in Engineering and Computing shows that attrition in engineering is higher among women than men. Passion for math and scienceLam Research VP Gowri Kamarthy took her Ph.D. in chemical engineering from UC Berkeley directly to Lam Research, where she’s spent the past 22 years in technical positions. Today she heads the company’s conductor etch product line.Coming from a family of engineers, including her father and siblings, Dr. Kamarthy had a built-in support system that was essential to her success. She never felt intimidated by male peers after spending her formative years pursuing her passion for math and science.“I may have stood out as a minority in the field of engineering, but there was also a silver lining in standing out,” she said. “People notice you.”Kamarthy realizes that engineering careers are generally perceived as being less compatible with family life, for both women and men.“Anyone who wants work-life balance in an engineering career will have to navigate its special challenges, including the need to work long hours to match the rapid pace of innovation,” Kamarthy said.Drawing from her own experience, Kamarthy offers some career advice. “Perseverance and grit are key to success,” she said. “The other ingredient is luck. I was fortunate to have great bosses at Lam who didn’t see gender first and foremost. Instead, they recognized my ability to deliver on projects and encouraged me to perform at my best.” A love for math and science. The confidence to excel in those subjects. A support system to help her through the bumpy times. These were also truths for Sandy Vos, Ph.D., director of R D at NXP Semiconductors.“I was always good at figuring things out,” says Dr. Vos. “I remember feeling enthralled when I got my first internship because it combined engineering, math, science and manufacturing.” Like Kamarthy, Vos was aware of her status as a woman in a male-dominated field, but it didn’t stop her.“If anything, my gender drove me to prove myself,” Vos said. “And I’ve been fortunate because everywhere I’ve worked, I’ve been a part of a smart and collaborative team.”That doesn’t mean gender never came into play. Whenever it did become an issue, Vos didn’t shy away from hard conversations. She recalls having a conflict on the plant floor with two men who each stood over six feet and were about 100 pounds heavier.“I had a conversation with them, and we figured it out,” she said. “But for a while there, my heart was racing.”Gender felt like a bigger issue when Vos was younger. “Now that I have gray hair, it’s not much of a concern,” Vos said. “But earlier in my career, I started putting Ph.D. on my business card so people would know I could talk technical details.”Though just one of three women in an undergraduate class of 35 engineering students – and with a teaching cohort of all-male professors – Debbie Gustafson anticipated equitable treatment in her college engineering program. She had the same outlook when she began her career in semiconductor manufacturing. But the belief that she’d receive the same treatment as her male peers went largely unfulfilled. This didn’t slow her down. During her first year as CEO of Energetiq, she grew the company’s revenues and valuation. A year later, she steered the company through a successful acquisition by Hamamatsu Photonics. Today Gustafson continues to lead Energetiq as a wholly owned subsidiary, but the road to the top job wasn’t without hurdles. Gustafson muscled through the tough times.“When I started out, I traveled to Japan and Korea when there weren’t other women in technical roles,” she said. “My first meetings were extremely frustrating. I was the only woman in the room, and the men wouldn’t address me. This went on for a year, but I kept coming back and built the relationships.”Now a member of the SEMI Foundation Board of Trustees, Gustafson credits mentors with helping her navigate the nuances of doing business across cultures during those early years.A rocket scientist among usAlissa Fitzgerald might tell you that MEMS isn’t rocket science. But that’s only because she has a Ph.D. in Aeronautics and Astronautics, which actually is rocket science. Dr. Fitzgerald worked at a government laboratory and a large defense contractor before she got her Ph.D. and moved to a MEMS industry startup. Though gaining valuable experience, she found the environments too hierarchical and lacking in career development opportunities for young female engineers. As one of the few women engineers at these heavy-duty engineering firms where, in the 1990’s, there were no women in leadership roles, Dr. Fitzgerald sensed that opportunities for her to advance were remote. Fitzgerald started her own firm rather than climb up the ladder of another company, but it turns out, her motivation had nothing to do with gender.“It was the way engineers were treated like Dilbert,” she said. “I felt like a cog in the wheel, working for corporations that weren’t nurturing or appreciative of engineers.”After years of working for other companies, Fitzgerald founded the eponymous AMFitzgerald Associates, a developer of innovative MEMS and sensor solutions for specialty applications. When gender did come up for Fitzgerald, it manifested in men questioning her technical abilities.“Early in my career, I felt like I had to prove myself worthy, even though my degrees were from MIT and Stanford,” she said.Over 3,000 respondents to the Workplace Experiences Survey, sponsored by the Society of Women Engineers and the Center for WorkLife Law at UC Hastings Law, validate Fitzgerald’s experience. 61% of women vs. 35.1% of white men surveyed cited Prove-It-Again Bias – “having to prove themselves repeatedly to get the same levels of respect and recognition as their colleagues.” For engineers of color, that disparity was even worse. 68% of engineers of color (both women and men) reported Prove-It-Again Bias vs. 35% of white men.“For women and people of color, there’s rarely an assumption of competence,” Fitzgerald said.It’s sad but true that we can’t decouple the challenges women face from the challenges people of color face. Both are dramatically underrepresented as chip companies, and women of color represent the smallest percentage of the industry’s workforce and leadership.Inclusivity mattersWorking toward gender equity isn’t just a case of doing what’s right. It’s a case of doing what’s profitable. Research shows that companies with more women on the board perform better.“Given the pace of innovation in semiconductors, we need people from different backgrounds and perspectives to solve the hard problems challenging our industry,” Kamarthy said.Vos appreciates the fact that SEMI is creating a forum of inclusion.“Inclusion starts when you’re young,” she said. “School-aged kids are already making decisions about a future they see as exciting and possible. Our job is to make sure they have the opportunities to pursue what they envision.”Change won’t come magically, though. Fitzgerald believes companies need to make a concerted effort to attract a diverse population.“While I see a disproportionate number of female applicants, I’m more the exception than the rule,” she said. “When male executives call and ask, ‘How are you finding all these amazing female engineers?’ I say, ‘they’re finding me.’”Elevate the storyAchieving gender parity in microelectronics is a daunting task. Fortunately, access to SEMI’s global membership puts us in a unique position to make this deeply complex story clear and relevant to our members, so we can help support the shift.We’re looking at both the stark numbers of women working in microelectronics and at the lack of longevity of women in engineering. We’re elevating the conversation about childhood education. Why are girls passed over in math and science classes in early grade school, and what is the effect of teachers’ lowered expectations for girls taking these classes? What does it mean to be the only in the room? The only woman, or the only woman of color, on a team or in a meeting room. Feelings of isolation or disengagement – or frustration with Prove-It-Again bias – often lead to turnover in an industry that already struggles with retention.Reverse the trendThere’s much SEMI members can do to work toward gender parity in our industry. Look at recruitment, hiring, retention and promotion processes to see how women fare in them. Consider how to create a company culture of self-awareness and inclusion. Ensure equitable pay. Suggest and request women speakers for keynotes and panels at conferences. And offer workplace flexibility to allow women – who often bear most family responsibilities – to take time off or reconfigure schedules so they can help care for children or ailing parents.It’s time for our industry to reverse the trend of gender inequality. Research shows that companies with greater gender and racial parity are more productive, innovative, and profitable. If we welcome and support women in our companies, we will help women – and our industry – reach their full potential.Get involved with SEMIRegister for the Women in Semiconductors (May 3, 2021).

The pandemic unleashed by the coronavirus SARS-CoV-2 (which causes the disease COVID-19) has infected over 100 million and resulted in over 2.6 million deaths worldwide as of March 2021. It is well-established that this virus primarily spreads from person-to-person via respiratory droplets produced when an infected person coughs, sneezes or even breathes (see Ref. 1-3). Subsequently, the droplets meet the eyes, or enter nose or mouth of a nearby person, or transmit when a person touches an infected surface, then contacts their eyes, nose, or mouth. Since the virus is small, 0.06–0.14 microns in diameter, many copies can be contained in or attached to emitted respiratory droplets. Droplets as small as one micron can carry enough viral load to cause an infection. A particular concern is the interaction of droplets with ventilation systems, which potentially could enhance the propagation of pathogens. This has implications on situation-specific safe distancing and the design of building filtration systems, air distribution, heating, air-conditioning and decontamination systems. A particular instance of this is the semiconductor manufacturing cleanroom, where systems and protocols are specifically designed to minimize contamination. The $440 billion global semiconductor industry depends on these cleanrooms for integrated circuits (chips), and in turn, these chips form the lifeblood of the multi-trillion-dollar global electronic systems industry. Electronic systems are now critical for just about every aspect of human life, including health, work, finances, entertainment, transportation, power grids and many others. Thus, it is critical to understand how cleanrooms can operate more safely to ensure the health of workers while maintaining productivity levels to meet increasing global demand for semiconductors. In the work described here, we analyzed particle and droplet transport via modeling, simulation [Refs 1-3], and experimentation [Ref. 4] to help guide the industry. Modeling and Simulation In this part of the work, mathematical models were developed to simulate the progressive time-evolution of the distribution of locations of particles produced by a cough. Analytical and numerical studies were undertaken. The models ascertain the range, distribution and settling time of the particles under the influence of gravity and drag from the surrounding air. Beyond qualitative trends that illustrate that large particles travel far and settle quickly – versus small particles that do not travel far and settle slowly (yet can be carried far by ambient flow) – the models provide quantitative results for distances travelled and settling times, which are needed for constructing social distancing policies and workplace protocols. Figure 1 shows examples of the results of the modeling and simulation work. Figure 1: Model of particle spreading from a person coughing, with and without a mask. (Ref. 1) Following are key insights from the modeling and simulation work (Ref. 1): Large particles travel far (launched “ballistically”) and settle quickly, while small particles do not travel far and settle slowly (when there are no ambient externally-driven flow fields). Small particles do not settle even by the end of the simulation time (4 seconds in Ref. 1). Accordingly, the simulations were also run for extremely long periods to ascertain that the “mist” of small particles remained airborne for several minutes (as predicted by the theory). For strong opposing headwind, small particles move backwards, yet still remain airborne for extended periods of time. This is by far the most dangerous case since this will encounter other persons at the torso level. Ratio of the general drag to gravity indicates that at high velocities, the dynamics are dominated by drag. For general cough conditions, there can be cases where the change in the surrounding fluid’s behavior, due to the motion of the particles and cough, may be important. One major implication of this work is that the challenge of infection must be addressed both spatially and temporally. In other words, it is necessary to maintain social distancing based on how far the virus travels, but it is also important to account for how long the virus stays at the location because of specific air patterns. On the positive side, understanding these spatio-temporal patterns accurately will enable companies to design (or re-design) ventilation and decontamination systems precisely to improve worker safety. Other aspects of this analysis entail contact tracing (Ref. 2) and decontamination (Ref. 3). Further details, including simulations, are available at https://msol.berkeley.edu/publications/. Experimentation The major vector of coronavirus spread is through respiratory droplets expelled when coughing, speaking, and breathing; and the efficacy of any safety measures depends on accurate characterization of the dispersal of these droplets. The term particle describes objects that begin their journey as a solid. The term droplet is reserved specifically for objects that are initially liquid, albeit it is important to note that droplets can evaporate and effectively transform into solid particles composed of non-evaporative material. A purpose-built room, the Cal Covid Cube, C3, was set up and utilized for this research [Thatcher et al. 4]. The C3 is a parallelepiped room that is 232 centimeters tall, 376 centimeters long and 284 centimeters wide on the inside. For experimental results to be meaningful and repeatable for scientific and practical purposes, it is essential that the experimental setup be carefully controlled and calibrated. The following precautions were taken to ensure this: Charge-free: When solid particles are released, it is critical to eliminate (or thoroughly know) static charge effects for obtaining accurate deposition patterns. Static charge effects can manifest through particle-particle interactions (affecting particle motion in flight) or particle-surface interaction (affecting deposition pattern). Two methods for the elimination of charge effects on the deposition surface were found to be effective: (1) ionized non-conductive adhesive sampling strips, and (2) grounded aluminum backed carbon sampling strips. Isothermal: The room is a converted walk-in freezer with 10.5-13 centimeter thermal insulation and located in the middle of a building, at least 5 meters away from all building walls. Temperature uniformity was checked and the C3 room temperatures were found to be isothermal within uncertainty of measurements. Quiescent: It was ensured that the room did not create uncontrolled thermal convection due to isothermal nature. Quiescence was verified with both hot-wire measurements and with free-falling particle drift observations. Isopotential: The outer and inner surfaces, including the door of the C3 were conductive aluminum and stainless steel, and copper tape were used to ensure reliable electrical connection of door, interior and exterior panels. Electric fields were surveyed and found to be negligible within precision of instruments. Other design elements: All interior surfaces were coated with black matte paint to reduce scattered light and provide uniform background for imaging measurements. The facility was located on ground floor to limit vibrations. Repeatable Launch: To emulate the release from a true cough or sneeze, and to better understand droplet motion in a canonical turbulent jet versus a cough type release, we studied different layers of complexity for the release geometry: (i) Straight round pipe (ii) Smooth 90-degree curved pipe, with a changing radius along the length of the pipe (iii) Intubation trainer doll, with realistic airways and mouth/tongue structure Figure 2 shows the experimental setup with the intubation doll in C3, with the particle/droplet release being measured after deposition on the sampling strips that appear green. Figure 2: Experimental Setup in C3 with both charge neutralized (white appearing green) and conductive (black) sampling strips placed on a conductive and grounded alignment grid [Ref. 4] We utilized both liquid droplets and solid particles. For droplets, we explored and found promise in a method of deposition analysis based on fluorescence. For particles, we explored many ways in which the smallest of thermal gradients or electrostatic charge issues can affect the data and developed practical methods to address these issues. For accurate measurement free of static charge effects even in environments where high ambient flow velocities may cause a nonconductive surface to rapidly acquire charge (e.g., clean room environment), we developed carbon-tape-based sampling strips that are cleanroom-compatible, conductive, and grounded. For analysis, we developed a cost-effective method utilizing a commercial photo negative scanner followed by image enhancement by blind deconvolution. Figure 3 shows sample results for particle deposition location along our centerline for particles in the ballistic, intermediate and aerosol regime. Figure 3: Experimental Results [Thatcher et al. 4] Following are key insights from experimental work: Significance of both static charge effects and thermal gradients in rooms for validation tests are more than usually appreciated. For modelling, accounting for the non-uniform initial particle velocity matters for the ballistic particles. For all sizes of particles, simulating the transient versus steady state significantly impacts predicted particle spread. Thermal plumes alone from humans along particle flight path can transport 50 micron particles across the room. In some situations, this was observed up to ~6 meters. There is a significant effect of Relative Humidity (RH) and temperature on droplet evaporation. The practical consequence is that, in low RH, particles spread further, with all other things being equal. (The reason is that particles shrunk more and entered the aerosol regime.) In summary, a systematic analysis of particle and droplet transport was conducted by simulation, modeling, and experimentation. We were able to develop robust, rigorous, and repeatable methodologies and draw meaningful insights that will support safer operation and productivity of semiconductor cleanrooms globally. Further, these studies will help with the design (or re-design) of ventilation and de-contamination systems that help protect both the health of humans and the economy from current and future pandemics. This article provides a high-level overview of the work, and further details will be available through a series of scientific papers that are in various phases of publication.

Semiconductor process development is no easy task, with each generation of devices more difficult and expensive to create. Traditional cycles of build-and-test development are becoming obsolete, since they are too expensive and time-consuming for the most advanced processes.The High Cost of Process DevelopmentMost chip designers developing new products rely on existing manufacturing processes, but someone had to create those processes to make the designs possible. The goal of process development is to create new semiconductor manufacturing processes that provide high yield while achieving the required device performance. In contrast to new chip design, however, it requires an entirely different set of engineers and skills.The traditional approach to process development involves building multiple test wafers to determine the ideal process for a given device. After one set of wafers is fabricated and analyzed, insights from the previous round help to refine process steps for another round of fabrication. Due to smaller feature sizes, each new process generation is more sensitive to variation. This adds even more complexity because smaller feature sizes and parasitic effects require more measurements and testing as well as additional fabrication. The cycle is repeated many times before the entire process flow can be finalized, making it time- and cost-intensive, especially for the most advanced technology nodes.Testing Virtual Wafers Instead of Real WafersToday, there is an alternative to this slow, expensive way of doing things. Virtual fabrication lets computers simulate all of the processing that occurs when real wafers are built. These virtual models allow semiconductor process engineers to test manufacturing equipment settings with far greater variation than is possible in a physical fab. Designers can simulate the entire process flow, running the equivalent of thousands of wafers in days instead of months. Designers can quickly see graphical animations to visualize process steps, modify process recipes and device geometries, and measure how these changes affect electrical behavior.Improving Yield Using Statistics in Virtual Wafer FabricationBecause of the high volume of data generated, designers are turning to statistical analysis to provide greater confidence in their choice of process settings. Defects and random variations can be modeled in a virtual fab in a way that’s not possible in a real fab, letting developers test the sensitivity of the device structures against the unpredictable aspects of processing.There’s more than one approach to optimizing the process settings used in a new memory or logic fabrication sequence. The simplest one involves taking a single variable and exploring its effects. Critical dimensions (CDs), for example, establish those feature sizes of a device that ensure desired electrical performance. A particular dimension can be swept from low to high values – developers can then measure the effects of that range on device behaviors such as threshold voltage. This allows developers to ensure that the electrical behavior of their device design addresses the range of expected feature sizes and variability. The interactions with intersecting process steps can also be tested for further validation, since these interactions can lead to unanticipated device performance.But, in reality, this approach isn’t sufficient for studying the complex web of interactions between process steps and the resulting structures.A second approach leverages Monte Carlo analysis, randomly varying a wide range of process and device parameters and calculating the resulting device geometry and performance. This data can be used to automatically identify the process and design settings needed to achieve yield and performance goals. It’s an area where simulation shines, providing a useful way to test the interactions between many different processes.Statistical experiments using virtual fabrication illustrate step-by-step methodology to optimize process and design settingsVirtual Fabrication PlatformSEMulator3D is a virtual fabrication platform created by Coventor, a Lam Research company. It allows the definition of all process steps, the modeling of devices, the collection of metrics, electrical and device analysis, the statistical analysis of results, and the visualization of process steps through graphical animation. Today, semiconductor companies use it for both optimizing and scaling leading process nodes and for developing advanced new technologies like GAA (Gate-All-Around) transistors.The ability to do this work virtually is the future of semiconductor process development. Virtual fabrication accelerates new process time-to-market by months, opening up market opportunities worth hundreds of millions of dollars for semiconductor companies.Visualization of process steps of a Gate-All-Around transistor shows 3D construction in SEMulator3D.

Post-Conference Report: SEMI Heterogeneous Integration SummitDemand for high-performance computing (HPC) chips is exploding. These super-speedy chips are critical for data centers and cloud computing infrastructures to support new performance-hungry technologies such as artificial intelligence (AI) and 5G. The challenge is for the devices and their multi-core architectures to couple high bandwidth density with low latency and high energy efficiency. Heterogenous integration offers a potential answer as an advanced packaging technology designed to meet these skyrocketing performance demands on HPC chips and open the door to a whole new world of 3D integrated circuits (ICs).So important are 3D ICs that Intel and TSMC representatives speaking at the recent Heterogeneous Integration Summit hosted by SEMI Taiwan in Taipei declared that the packaging technology will all but dictate the future of the industry. All told, 12 speakers from government, academia and a broad range of leading international companies from sectors including advanced packaging, design, manufacturing, silicon photonics, equipment and materials shared forward-looking strategies, the latest technologies and potential heterogeneous integration market opportunities. Koushik Banerjee, vice president, TMG, Assembly, and Test Technology Integration, at Intel pointed out that using heterogeneous integration for a single SiP (system-in-package) will deliver what the industry has long wanted by enabling multiple process nodes, more diverse silicon IP (intellectual property) and chip functionality, and chips that pair low energy with high frequency. Intel plans to announce its first Forveros 3D packaging product combining a 10nm HPC chiplet with a low-energy 22nm base die and stacked with memory on top. When asked about the future of advanced packaging technology, Banerjee said it will be very much about the combination of Foveros and its very own Embedded Multi-Die Interconnect Bridge (EMIB).For its part, TSMC, will continue to upgrade its CoWoS (Chip-on-Wafer-on-Substrate), InFO (Integrated Fan-out) and other 2.5D IC production solutions while developing 3D chip stacking technology such as SoIC and WoW (wafer-on-wafer). TSMC is ushering in a new age of 3D IC packaging, said Marvin Liao, Vice President, Backend Technology and Service Division, at TSMC. The company’s SoIC is based on Chip-on-Wafer concept, with the flexibility to support one-to-many or different process nodes, whereas its WoW integrates two wafers with solid yields that could be used for products of the same size or manufactured with mature process technology.Speakers also included representatives from ATOTECH, Lam Research, SPIL, Sigurd, Cadence, Grand Process Technology, ITRI (Industrial Technology Research Institute), Industrial Development Bureau, and Lee San-Liang, Distinguished Professor, Department of Electronic and Computer Engineering at National Taiwan University of Science and Technology all shared their perspectives on equipment, materials, and testing and how different industry value chains might contribute to the development of heterogeneous integration technology.Expected to be a key driver of the next wave of semiconductors, heterogeneous integration and related technologies – including 3D IC, FOWLP (Fan-out wafer-level packaging) / FOPLP (Fan-out panel-level packaging), silicon photonics, Micro LED, compound semiconductor, automated optical inspection and SLT (system level testing) – will be a key focus at SEMICON Taiwan 2019, September 18 to 20 in Taipei. The Heterogeneous Integration Innovation Zone – along with featured international programs such as SiP Global Summit, Strategic Materials Conference, the Smart Data Summit and the Smart Automotive Summit – will gather key industry players to reveal the latest technology breakthroughs and market trends.Emmy Yi is a senior marketing specialist at SEMI Taiwan.

According to market research and strategy consulting firm Yole Développement (Yole), the total market size of MEMS, sensors and actuators will double from $48 billion in 2018 to $93 billion in 2024.[i] The consumer market will continue to drive volume, with applications such as smartphones making up for in volume what they lack in average selling price (ASP). Stronger demand in automotive, biomedical/health, industrial, and voice-first applications (such as smart speakers) will support this upward trajectory. With so much growth ahead of us, how will the design and manufacture of MEMS keep pace with industry demand for higher levels of innovation and integration, lower cost and lower power, smaller footprints, and faster design cycles — all while meeting acceptable price points?We turned to a handful of MEMS manufacturing experts from SEMI-MSIG who will join us at SEMICON West 2019, July 9-11 at the Moscone Center in San Francisco, to explore the complexities of keeping pace with market demand for MEMS over the next decade.Address the Design GapMentor GM, ICDS Division Greg Lebsack and SoftMEMS President Mary Ann Maher see tremendous progress in the manufacturing supply chain for MEMS.

New MEMS-based products are constantly emerging, fueled by the Internet of Things (IoT), autonomous driving, smart manufacturing and healthcare applications. The MEMS pressure sensor market is no exception to this trend1. Its growth has been driven mainly by automotive applications such as tire pressure management system (TPMS) regulations in China, fuel and ignition systems, thermal systems, oil-pressure monitoring, and indoor and outdoor navigation systems. Easy to customize and integrate, miniature, sensitive, accurate and low-power MEMS devices are especially well-suited to the accuracy, power consumption, sensitivity and miniaturization that pressure sensors require.Yet MEMS design also presents some specialized challenges, such as a strong coupling between fabrication technology and design. Complex physical structures that exhibit non-linear behavior, custom packaging requirements, and a final product that requires integration with surrounding CMOS circuitry are just a few examples. What’s more, there is a lack of standardized processes and process validation in MEMS design ecosystems. Pressure Sensor (Courtesy: X-FAB) As with other products based on MEMS technology, designers must increasingly customize pressure sensors for higher performance – sensitivity and linearity, in this case – while decreasing their package size. Designers can accomplish the task by studying sensor performance and manufacturability using computer models prior to fabrication. This can ensure that the sensor meets its required specifications while simultaneously reducing manufacturing cycles and cost.The Power of CollaborationThis is where strong collaboration among EDA providers, MEMS technologists and designers delivers tangible benefits. EDA providers and MEMS foundries can collectively help MEMS designers to incorporate foundry process constraints into their designs.In the semiconductor industry, first-pass successful silicon relies on standardized manufacturing processes, thorough technology characterization, accurate model generation, established simulation and verification, and extensive reuse of proven design blocks. In the MEMS world, where processes and products are developed concurrently, and processes change with every product, is it possible to adopt standardized processes, design methodologies, and tools that enable efficient reuse of existing technology and design knowledge? The challenge lies in maintaining the flexibility to optimize products for a diverse array of requirements. The ideal design platform should ease sharing of technology and design data between the foundry and its customers, enabling two-way collaborative development and allowing foundry technologists to easily perform a feasibility assessment of a customer’s project. This approach offers important benefits, allowing designers to explore and evaluate the suitability of a foundry’s process technology in their unique application. It also supports accurate prediction of device performance prior to fabrication and reduces costly build-and-test cycles. Combining standardized manufacturing processes, MEMS process design kits (PDKs), and a proven design flow are the starting point for development of manufacturing-ready designs.A Real-Life Example using Pressure SensorsAn EDA company, Coventor (a Lam Research company), along with MEMS foundry partner X-FAB, collaborated to develop a PDK that would ensure that manufacturing constraints are automatically considered early in their design process. The design flow is based upon an X-FAB fabrication platform that supports multiple process options for the manufacturing of absolute and relative MEMS pressure sensors. The PDK is a “golden container” for all the process and material characteristics of the silicon membrane and substrate, glass, passivation layers, and piezoresistive components. It enforces material properties and guarantees their correct implementation during the simulation. It also includes a component library containing ready-to-use, 3D parameterized devices (such as membranes and resistors), all pre-designed with foundry-supported materials to support their respective design rules. The components are readily partitioned for optimized meshing and simulation, saving design and simulation time. Figure 1: The elements and design flow of the PDK designed by Coventor and X-FAB. (Courtesy: Coventor)Designers can use components from the library to create a custom design — which might include different membrane shapes and sizes, and resistors of varying shape, size and position — to simulate the impact of different technology variants (such as resistor doping profiles, membrane and substrate thickness, glass material properties, and passivation schemes). This allows them to anticipate the effect of these design changes on sensor sensitivity for varying pressure and temperature regimes.Extensive validation of the pressure sensor design platform is currently underway. So far, the simulations have exhibited very good correlation to actual device measurements across a range of pressure and temperature conditions, including predictions of non-linear behavior for various pressure sensor designs. At the same time, the simulation accounts for mechanical membrane properties and piezoresistivity. With this type of design platform, a foundry can provide guidelines to help customers select both the fab technology and design features that lead to an optimal design solution.

In addition to the design verification that the PDK provides, additional partnerships among foundries, integrated device manufacturers (IDMs), research centers, equipment suppliers, and EDA vendors will help to define requirements and solutions that address every level of design and production. These might include tasks such as describing standardized material properties and process specifications, creating accurate foundry-proven design models, and defining requirements for system-level simulation. In the future, PDK simulations might even include up to tape-out and physical verification.
