electronics industry

If you look at your clothes or shoes, there is a growing chance you will see the words Made in Vietnam printed on the tag. Since the United States lifted its trade embargo against Vietnam in 1994, the country has become the second largest exporter of apparel and shoes to the U.S. What may be less evident is the source of that new electronic gadget you received for Christmas, with its numerous parts, chips, and intricate supply chain. While light manufacturing has dominated Vietnam’s economic growth since the Đổi Mới economic reforms implemented in the 1980s, over the last decade the country has been repositioning itself to become a dominant player in the global microelectronics industry, a trend that has gained momentum in the wake of the U.S.-China trade war. In 2019, Vietnam ranked as the fourth largest exporter of electrical goods and components to the U.S. With exports doubling over the last four years and now exceeding $19 billion, surpassing Taiwan, Japan, and Korea (based on goods exported under chapter 85 of the Harmonized Tariff Schedule). Vietnam’s global electronics industry now accounts for about 40% of its exports, and the country seems to be just getting started. Early Entrants Though Vietnam owes its growing success in attracting foreign direct investment (FDI) in the semiconductor and microelectronics industries to the advent of China plus one – the business strategy to diversify business investments geographically – it was the few early entrants that gambled on this emerging market a decade ago that put Vietnam on the global stage. Of these early players, no other firm comes close to having the impact that Samsung has. It’s initial $670 million mobile phone manufacturing plant in the northern province of Bac Ninh in 2008 grew to a country-wide investment of $17.3 billion within a decade. Samsung is now Vietnam’s largest FDI contributor and accounts for more than 25 percent of its exports. Because of Samsung, Vietnam has become the second largest exporter of smartphones in the world. Around the same time, Intel opened its $1 billion semiconductor assembly and testing facility in Ho Chi Minh City, putting Vietnam firmly on the global technology map. More investors, like LG, Panasonic and Foxconn soon followed. Within a few years of these initial investments the industry was taking notice, illustrated by SEMI’s role in co-organizing the Vietnam Semiconductor Strategy Summits in 2013 and 2014. With SEMI SEA’s increased efforts to promote Vietnam as an important ecosystem in the electronics supply chain, more will be done to positively influence the growth and prosperity of its member companies in Vietnam. These early investors found Vietnam attractive for several reasons. Key among these are the country’s low wage rates combined with its favorable demographic structure – what the UN refers to as the golden population structure, which provides “Vietnam with a unique socio-economic development opportunity.” Companies are also attracted to the growing number of Free Trade Agreements (FTAs) that Vietnam belongs to, including the ASEAN Free Trade Area, CPTPP, the EU-Vietnam FTA, and, most recently, RCEP. Though the U.S. has yet to ink a trade agreement, the Singapore AmCham’s annual regional survey has consistently identified Vietnam as the most attractive country in ASEAN for a potential bilateral FTA partner with the U.S. Leveraging the Trade War If the plus one strategy was the catalyst that started this wave of electronics manufacturing in Vietnam, then the U.S.-China trade war was the enzyme that supercharged it. A common quip in Southeast Asia is that the U.S.-China trade war is over and Vietnam is the winner, and this is apparent in both trade and investment trends. According to the Asia Development Bank (ADB), the riff between the U.S. and China has caused a redirection in trade, as U.S. imports from the PRC fell by 12% in the first six months of 2019 while U.S. imports from Vietnam increased by 33%, with electronics and machinery accounting for the bulk of this jump. The ADB further reported that in a prolonged and intensified trade conflict, the worse-case scenario would result in Vietnam, Malaysia, and Thailand being the biggest winners, “in that order.” On the investment side, a March 2020 Gartner, Inc. survey of global supply chain leaders revealed that 33% had “moved sourcing and manufacturing activities out of China or plan to do so in the next two to three years.” While this survey did not mention specific winners, the ADB reported that “newly registered FDI in Vietnam from the PRC and Hong Kong rose by 200% year on year in the first seven months of 2019,” indicating the move of Chinese suppliers to Vietnam. Additionally, a review of recent press reports indicate firms like Apple, Nintendo and Dell are encouraging suppliers to move parts of their supply chains to Vietnam. These suppliers are complying, with Compal Electronics, GoerTek, HZO, Inventec, Luxshare Precision Industry, Pegatron, USI and Wistron all reportedly announcing plans for new investments in Vietnam. Manufacturing Hubs Within Vietnam, microelectronic facilities have concentrated in a few geographic hubs. In the south, the Saigon High Tech Park in Ho Chi Minh City attracted early entrants Intel and Samsung, with firms like Nidec and Jabil soon following. The largest investment capital, however, developed in the northern provinces that ring Hanoi. Bắc Ninh, an hour’s drive from Hanoi, was the site of Samsung’s first investment and has since attracted Foxconn and Canon. More recently, firms have been drawn to the port city of Hải Phòng, the country’s third largest city, which is already home to Samsung and LG. The city’s close proximity to other manufacturing clusters, its new deep-water port, and its expressway that provides a 12-hour trucking route to China’s electronics epicenter in Shenzhen are helping make the city Vietnam’s new high-tech production center. In 2019, LG Electronics moved its entire smartphone production line from South Korea to Hải Phòng, and in 2020 Pegatron reportedly chose the city for its $1 billion investment plan. Local phone manufacturer VinSmart is also producing the country’s first 5G smartphones in Hải Phòng. In November, USI, a subsidiary of Taiwan-based ASE Holding, broke ground on its first production base in Southeast Asia, a $200 million phase-one investment in the production and assembly of chips for wearable electronic devices. USI’s investment, which is moving into the internationally managed DEEP C Industrial Zones in Hải Phòng, is “intended to move us closer to our overseas customers and accommodate their ever-increasing demand,” according to Mr. Kuei Chun Chi, the firm’s Manufacturing Service Director. “North Vietnam, with its strategic geographical position and an extended infrastructure in place, offers USI an optimal way to facilitate fast and flexible response to customers' orders.” Though the Covid-19 pandemic has dampened the pace of new investments in Vietnam’s microelectronics industry, it has also amplified the country’s attractiveness to investors. Vietnam was successful in containing the outbreak through aggressive quarantine and contact tracing measures, and as a result its economy has the brightest outlook in the region. The ADB forecasts the country will be one of the fastest-growing economies in SEA in 2021, with GDP estimated at 6.8%. The Ministry of Industry and Trade is also reporting that several of the world's largest technology corporations plan to shift their production chains to Vietnam post-Covid-19, an indication that technology firms will accelerate relocation plans in 2021. Vietnam’s successful response to the pandemic, combined with its strategic location, low wage rates and foreign trade agreements, will ensure that the region continues to benefit from the shift in supply chains in Asia, making it the new destination for electronics manufacturing.

A lot has happened in fifty years, particularly when it comes to the microelectronics industry. Founded in 1970 by a group of semiconductor industry pioneers who believed that co-opetition — instead of traditional competition—would produce a more vibrant emerging industry, SEMI was born as an industry association.It's fitting during this week’s 50th annual SEMICON West (July 20-23, 2020) — a virtual event for the first time — that SEMI Chief of Staff Bettina Weiss offers her perspectives on the evolution of SEMI from one of the best seats in the house: the 24 years that she has spent helping the association change and grow.Vetrano: You’ve enjoyed a long rich history with SEMI, and now serve as the association’s first chief of staff. What roles have you played at SEMI up to this point?Weiss: I cut my teeth at SEMI by joining SEMI Standards, first serving as standards coordinator at SEMI Europe from ’96-’97. Over the next 11 years, I held a variety of positions at SEMI Standards, culminating with director of international standards from 2003-2008. Given that experience, I have to admit that SEMI Standards are still near and dear to my heart.I moved on to several leadership positions in our former global photovoltaics/solar business through 2014, and toward the end of that stint, I assumed additional responsibilities, becoming vice president of business development. That’s where I dove headfirst into expanding SEMI into emerging regions, including Vietnam, India and Latin America. SEMI goes where members see (or want to better understand) new opportunities, especially in places that had ambitious plans for fabs for microelectronics, including semiconductors and MEMS.In 2018, I became SEMI chief of staff, reporting directly to our president and CEO Ajit Manocha.Vetrano: Now I hardly know where to start! Since I have to decide, what does it mean to be SEMI chief of staff?Weiss: As the first chief of staff, I’ve been able to shape the position, combining the support of critical efforts driven by Ajit with additional project management responsibilities like our Smart Mobility initiative.Working with experienced leaders in our industry, such as the Board of Industry Leaders (BIL), is one of the more rewarding parts of my role at SEMI. The BIL is a group of global executives tasked with advising SEMI on strategic planning, especially when it comes to future-looking initiatives like Smart Mobility, Smart MedTech, Smart Manufacturing, and Smart Data/AI.A lot of the other things I do are meant to support the whole SEMI organization, in partnership with other senior leaders such as Michael Ciesinski, vice president of technology communities, as we create business plans and examine new revenue models that will keep SEMI sustainable and viable for the future. This includes issues as varied as workforce development and diversity and inclusion, and the new digital platforms we use to engage with our members.Vetrano: How does SEMI Smart Mobility initiative exemplify the model of engaging end customers in vertical markets that are important to members?Weiss: When you look at the rapidly increasing number of chips and sensors in and around vehicles, Smart Mobility at its core brings together both the semiconductor/sensor and automotive/mobility supply chains for a more transparent dialogue about needs and wants along the entire supply chain. We are thrilled to count automotive OEMs Volkswagen and Audi as SEMI members. We also work with Tier 1 suppliers such as Continental and many others to promote the open exchange of ideas and foster collaboration among all stakeholders.Smart Mobility is a good example of how SEMI connects two worlds that are now interdependent for the mutual benefit of all players. Automotive companies and component suppliers want to better understand new technology capabilities that enable tomorrow’s infotainment, safety, security and communication protocols. And semiconductor, sensor and component companies see huge upside in supplying the equipment, materials, devices and subsystems that enable the future of mobility. Smart Mobility is a win-win, and the founding concept of our Global Automotive Advisory Council (GAAC).Vetrano: As we look to COVID-19, the single most important event to influence the microelectronics industry — and every other industry — why is SEMI membership more important now than ever?Weiss: Our industry is facing a triple whammy of challenges: a global pandemic, ongoing global trade tensions that impact interdependent supply chains, and a global economic crisis. All these challenges will require our members’ ingenuity, innovation and collective action to overcome them. But inherent in those challenges are tremendous opportunities, and I have no doubt that our members and the entire global electronics ecosystems will find ways to help everyone prosper and advance.COVID-19 has had a huge impact on our members. From the onset of the pandemic, we’ve provided our members with resources including best business practices, insights and data from industry experts to help them respond to a virus that has already changed so many things we took for granted before March. Additionally, SEMI has also advocated with governments around the world on behalf of the industry for essential business status and essential travel to sustain operations. Visit SEMI COVID-19 Resource page for information on industry best practices and much more.Vetrano: Before we look forward, what has changed dramatically in microelectronics since you started at SEMI?Weiss: Through my work with SEMI, I’ve witnessed dynamic, dramatic and sustained change in the microelectronics supply chain. Into the late 1990s, SEMI represented primarily semiconductor equipment and materials suppliers, and we worked with chipmakers – our members’ customers. That’s where a lot of important Standards work happened, for example, and the supplier-device maker relationship was pretty much our world. Over the years, we saw significant change in how companies partner and do business with one another. The digital transformation we’ve been witnessing for the past few years was the impetus for expanding our reach to bring companies in the extended electronics manufacturing and design supply chain together, from sand to system, so to speak. That was also when we invited associations representing flexible hybrid and printed electronics (FlexTech), MEMS and sensors (MSIG), and electronic system design (ESD Alliance) companies to join SEMI and our other technology communities for maximum cross-pollination. That’s because everything needs microelectronic devices and systems. Vetrano: Looking ahead now, what is can the microelectronics industry do to benefit humanity?Weiss: Semiconductors and sensors are often the unsung heroes of progress. Microelectronics can help bring prosperity to the billions of people now struggling on our planet. It can improve access to education for people through e-learning, it can advance agricultural production and streamline the food supply chain to help feed the world’s hungry, it can monitor the quality of the water we drink and the air we breathe, and it can get you in front of a doctor even in the most remote village in India.The beauty of microelectronics is that we are not gated by innovation. As the brilliant visionary Arthur C. Clarke once said, “The only way of discovering the limits of the possible is to venture a little way past them into the impossible.”As an industry association that helps technologists to venture beyond “the limits of the possible,” I invite like-minded technology adventurers to engage with SEMI, starting with registration to this week’s SEMICON West – our first virtual show.As chief of staff, Bettina Weiss reports to SEMI President and CEO Ajit Manocha and manages a broad portfolio of responsibilities. Major focus areas include advancing specific global strategic initiatives such as thought leadership (Think Tanks) and SEMI Smart Transportation vertical application platform, improving organizational efficiency, alignment and financial sustainability, acting as senior liaison to SEMI Board of Industry Leaders, leading strategic partnerships and M A activity, and supporting Manocha in creating a highly effective, agile global association.Maria Vetrano is a PR consultant at SEMI.

Humanity has survived almost unimaginable challenges over the past 5,000 years of documented human history. From war, famine and natural disasters to the first global pandemic in the last 100 years, more often than not, people have relied on one another to survive and thrive again. As the industry association representing the global microelectronics industry, SEMI has similarly made collaboration and community integral to the fabric of its organization. From helping members to succeed through the COVID-19 pandemic to facilitating member-driven industry standards around environmental health and safety, materials, and manufacturing capabilities, this approach shows members that standing together is better than standing alone.On the eve of the 50th annual SEMICON West (July 20-23, 2020) — the first virtual edition in SEMI’s history — I spoke with SEMI’s vice president of technology communities, Michael Ciesinski, about the role of SEMI in tackling big challenges through an active member community intent on solving problems through collaboration.SEMI: How long have you worked with SEMI and in what capacity?Ciesinski: In January 2016, I started my second tour at SEMI when FlexTech, the industry consortium I’d been leading, became SEMI’s first strategic partner. Nearly two years into that role, SEMI President CEO Ajit Manocha asked me to form Technology Communities to engage members with common interests. After FlexTech, we brought on the Fab Owners Alliance, then MEMS Sensors Industry Group (MSIG), and later the Electronic System Design Alliance (ESD Alliance).SEMI now has more than 20 communities in all, including Smart MedTech, Smart Data AI, Smart Manufacturing, Electronic Materials, and Integrated Packaging, Assembly and Test.SEMI: What is your role with Technology Communities — and how do members stand to benefit?Ciesinski: The leadership of Technology Communities ensures that SEMI’s benefits and services align to our members’ interests so we can provide member benefits that matter most. This spans forming communities where people hold common interests (e.g., advanced packaging) to facilitating standards that will promote intelligence in manufacturing (e.g., data standards for AI and machine learning) as well as providing R D funding.I’m especially proud that over the past three years, SEMI has brought more than $40 million in R D funding to our members, with most grants in the $500,000-$1 million range. We’ve been especially successful in securing funding in flexible hybrid electronics (FHE) through U.S. Army Research Laboratories (ARL), a model we first developed through FlexTech.Two recent recipients of FHE funding, GE Research and ITN Energy Systems, show how the grants are spawning partnership opportunities among commercial enterprises, R D organizations and universities. In developing lightweight, non-invasive wearables, including a human-performance sweat-monitoring patch that remotely analyzes sweat to detect hydration levels and other vital signs, GE Research is using key components such as sensors and lightweight batteries in its designs.ITN Energy Systems designed a flexible all-solid-state lithium battery that’s printed on light, flexible substrates to power small and incredibly thin applications.Universities are also benefiting by plugging into the SEMI ecosystem. In fact, 40-50 percent of funded projects are seeding commercialization by universities. This is another validation that SEMI’s collaborative, community approach to microelectronics is working.SEMI: Position, Timing and Navigation (PNT) is another hot area where SEMI has secured ARL funding. What makes this funding different and why is it important?Ciesinski: The PNT grant makes ARL funding available to the MEMS Sensors Industry Group (MSIG) members through SEMI for the first time. If you’ve ever lost GPS signal while coming out of a tunnel, you know how frustrating that is. For us, that’s an inconvenience, but for a healthcare worker in a remote location who’s waiting for a delivery of medication by drone, it could be life-critical. While that’s just one example of why we need PNT to operate when GPS isn’t available, I can imagine dozens of other important dual-use cases, including autonomous driving.SEMI: How else do Technology Communities benefit under SEMI?Ciesinski: Technology Communities need access to diverse resources to spur continuous innovation. Electronic Materials Group participants, for example, need to stay informed on regulations coming out of Asia, the U.S. and Europe that may affect their businesses. Where else other than SEMI can like-minded stakeholders congregate with people up and down the supply chain to determine whether industry-wide action is needed on regulation?SEMI: What is the importance of SEMI’s global footprint?Ciesinski: I’ve worked with many associations and managed major industry consortia. The clear advantage of SEMI is our global footprint. And that’s vital because microelectronics is a global industry involving a multitude of stakeholders that play essential roles in the supply chain.Let’s say you want to discuss EU regulations on hazardous chemicals. Rather than decipher these complexities alone, you can pick up the phone to speak with someone on SEMI’s European team to learn what’s critical.What if you’d like more information on the 20-plus new fabs that are going up in China? You can explore that question with our SEMI China or SEMI Industry Research and Statistics teams.SEMI: How has SEMI evolved over the years?Ciesinski: SEMI has a long history of providing what the industry cares about. We started in trade shows and pivoted to industry standards. We began with small silicon wafers and wafer carriers, and now within the span of 50 years we’re working on data-format standards that will support the application of AI and machine learning (ML) in the semiconductor industry.While highly varied today, data-format standards will help component manufacturers refine processes to create more efficient solutions. This ARL-funded program, which pairs SEMI members with the grant recipient, Cornell University, may offer dramatic gains in the productivity of semiconductor manufacturing.SEMI: How does SEMI’s approach to COVID-19 reflect core values of collaboration and community?Ciesinski: Together with Ajit Manocha, CMO Terry Tsao and other team members at SEMI, we pulled together a task force to help SEMI members navigate the pandemic.We tapped two existing groups, Environment, Health and Safety (EHS) and Information Technology Leadership (ITL) from the start, documenting their strategic and tactical approaches to help all members through the COVID-19 resource section of our website. The EHS section provides tips on facilities and meetings, employee policies, business travel and communications, while the ITL section lists insights on computing hardware for staff, licensing, networks, security and employee policies.Our EHS leadership team, which includes Entegris, Axcelis, Versum, and Intel, immediately started sharing best practices for sanitizing facilities. As a result of team meetings, SEMI EHS shared best practices on keeping the workforce remote and guidelines for returning people to work safely. From securing PPE and safeguarding employees and visitors by performing thermal scanning to outlining communications around potential employee exposures, EHS has provided meaningful resources for the benefit of all members.SEMI also took immediate steps in the area of advocacy. Our advocacy team in Washington, D.C., together with regional SEMI presidents around the world, have ensured that semiconductor facilities were and still are considered essential businesses in the U.S., Europe and Asia. That’s because microelectronics are foundational to fighting the pandemic.Microfluidics are critical to the Reverse Transcription (RT) Polymerase Chain Reaction (PCR) tests most commonly used for COVID-19. Sensors are embedded in the pulse oximeters that allow patients and healthcare professionals to monitor a vital rubric: oxygen saturation level. If oxygen saturation level drops into the low 90 percentiles or below, it may be time to go to the hospital for treatment.Microcontroller units are essential components in a wide range of hospital equipment, including the ventilators that may make the difference between life and death in the most seriously ill patients.SEMI: How can the ingenuity realized through microelectronics continue to help us tackle other big problems? Ciesinski: We have MEMS and sensors to thank for distributed intelligence, giving us the ability to put sensors anywhere, locally based in the field or in the packaging house.Food production is a prime example. Leveraging miniaturized wirelessly connected sensors, we can trace food through the entire production lifecycle, from the seed in the ground to the food in the warehouse and, ultimately, to the product that lands on the table.From larger enterprise such as IBM Food Trust to small startups, we’re using MEMS and sensors to improve crop yields so we can feed a human population that’s growing each year.There’s a sustainability piece as well. We’re using MEMS and sensors to reduce the amount of fertilizer or other nutrients or chemicals in the soil. That’s good for the environment and for the agricultural workers who labor in the fields.MEMS and sensors can also condense the time it takes to perform a specific task, conserving human resources.SEMI: Where do you think SEMI will go in the next decade?Ciesinski: Ten years from now, I believe we will still have our global footprint in place. I expect it will expand, particularly in Asia.We may also expand into new areas such as Latin America and Central America, which would provide at least two major benefits: People working in microelectronics would, I hope, have access to better quality of life. And diversifying the supply chain would allow nations and regions to have more control over the products they need, from PPE to medications, which may help us to better manage through the next pandemic.I am also hopeful that SEMI will be on the leading edge of helping our members communicate in much different fashion from what we have today. We’re already expanding beyond the paradigm of in-person meetings for standards meetings and conferences. As we move forward, I think we’ll see a hybrid solution to doing business, combining in-person meetings with virtual conferences and digital content that’s available 24/7.Whatever changes we see in SEMI, I’m confident that we will continue to see a global footprint in an industry association that prioritizes connections among members.Engage in the SEMI experience at upcoming SEMICON WestRegister today to hear from keynote speakers such as environmental advocate and former U.S. Vice President Al Gore, futurist and author Steve Brown, and IBM Research senior vice president and director Dr. John E. Kelly III, and Lea Gabrielle, special envoy of the Global Engagement Center for the U.S. State Department, at SEMICON West , July 20-23, 2020. Content will be live streamed and available on-demand. Michael Ciesinski is vice president of Technology Communities for SEMI, the global microelectronics industry association, appointed in August 2018. At SEMI, he directs activity for more than 20 industry groups, oversees the association’s R D funding program, and develops new technology initiatives to serve SEMI’s 2,400 members. Prior to re-joining SEMI, Ciesinski was president/CEO of FlexTech Alliance, an industry consortium focused on new methods of creating electronics. From 1995-2008, Ciesinski served in a similar role at the U.S. Display Consortium (USDC), a private/public partnership chartered with building the infrastructure for electronic display and flexible electronics manufacturing. Both FlexTech and USDC annually sponsor multimillion dollar technology development programs and provide industry technical, financial and market services. Ciesinski is a graduate of the University of Albany, NY, and a former member of the Dean’s Advisory Committee at California Polytechnic State University.Maria Vetrano is a PR consultant at SEMI.

Sapphire is a precious gemstone, consisting of aluminum oxide (α-Al2O3) with occasional traces of other elements such as iron, titanium, chromium, vanadium or magnesium. While sapphire stones found in nature mostly go to jewelry applications, the lab-grown sapphire – produced in a scale of up to several hundred tons per year – is widely used by the electronic industry. Now one can hardly find a branch of technology where this crystal is not used.Sapphires are mainly applied in infrared optical components, high-durability windows, wristwatch crystals, and the very thin electronic wafers used as the insulating substrates of solid-state electronics. High thermal conductivity, low reactivity, and appropriate unit cell size make sapphire an ideal material for a wide range of such electronic substrates for manufacturing of components such as LEDs and CMOS chips.SEMI spoke with Ivan Orlov, CEO of Scientific Visual, after his presentation at SEMI Strategic Materials Conference at SEMICON Europa, 12-15 November, 2019 in Munich, Germany, to learn more about the future of sapphire.SEMI: Why is sapphire an ideal material for a wide range of electronic substrates? Orlov: Sapphire undoubted advantages are its chemical inertness and ability to withstand high temperature, radiation and mechanical loads. In addition, it exhibits low dielectric loss and very good electrical insulation that makes sapphire a good candidate for substrates for LEDs and laser diodes or wafers for epitaxial growth. However, the most important advantage is that sapphire crystal lattice does very well matching semiconductor materials deposited to its surface, in particular nitrides of group III elements. To plainly benefit from these features, the grown sapphire must have as few macro- and micro-defects as possible, as substrate defects are inherited by semiconductors layers grown on the substrate surface. Hence the importance to detect defects in the raw sapphire material. This is the area where our team at Scientific Visual contributes. SEMI: Flaws are usually identified only after costly wafering and polishing steps, because rough surface of raw crystals prevents detection of the defects. What can be done to prevent defects?Orlov: Today, major players are investing in growing larger crystals without mastering in depth the growth process. Let’s face it, the semiconductor substrate industry, which is primarily based in Asia, is using empirical research methods. The raw sapphire boules are still inspected manually, and this qualitative assessment is exploited in two folds. The first step is to further process the boule. Furnace operators then adjust the growing parameters depending on the results of the manual inspection.Due to the lack of visibility into internal crystal defects, the crystal growth and its downstream processing remain an art rather than a science. The primary reasons are the difficulty to measure, locate and quantify precisely the defects in the full crystal volume. Scientific Visual equipment enables defects in raw boules to be fully quantified and categorized. With such objective measurements and knowing the full set of growth parameters, the Process Engineering (PE) team can, with the assistance of deep learning algorithms, considerably improve the growing process. Our quality control tools give Process Engineering team the “eyes” to see complete defect distribution in raw crystals, enabling it to make minor modifications in the growth process to improve yields, reduce costs and shorten the time to market for products.SEMI: What lead to those advancements and what problems did your team set out to solve? Orlov: Breakthroughs in immersion tomography, machine vision and parallel computing drove advancements in automated quality control technology. Previously crystal inspection accuracy was limited by the acuity of the operator’s eye and subjective bias. Light distortion and the diffusion of crystals made it impossible to accurately identify internal defects.Scientific Visual equipment give operators an undistorted 3D view of all defects in a crystal boule or ingot. However, only deep learning technology can correlate a hundred thousand growth data points to identify a final defect pattern.Defect pattern in non-processed item cored from EFG sapphire plate. Well visible is a typical wavy pattern of surface layers and sandwich structure in the volume. Color code marks sapphire defect density: from deep blue (non-defective material) to deep red (highest defectiveness.) SEMI: What challenges are addressed by your approach? Orlov: Increasing the yield of semiconductor substrates like Sapphire, Gallium Nitride and Silicon Carbide is paramount to reducing the price of wafers while increasing their quality. The upstream growth and downstream wafering processes are not deterministic. So far, most of the producers can only determine the quality during the late stages of the process. This condition creates huge constraints for teams in charge of production and processing. Automated Quality Control (QC) at the early stage of the production chain relieves all the unknowns, ultimately reduce the cost of material.SEMI: And what are the main opportunities?Orlov: There are massive opportunities to increase the yield and to ease the full processing chain from growth to the wafering process. Objective Quality Control (OQC) paves the way to industry-wide standards that categorize crystal quality at each step of growth to enable full certification of the defectiveness of the material and facilitate its trade and exchange.SEMI: What’s one of your predictions for the future of new materials?Orlov: The explosion of e-mobility and electric vehicles and the development of other green technologies will drive rising demand for low-defect sapphire, silicon carbide and gallium nitride substrates thanks to the streamlining of the full processing chain. Manual quality control will soon give way to full automation as quality control in sapphire and other raw crystals production is the only missing link in a fully automated semiconductor production chain. I believe that in five years, automated raw crystal inspection will become standard in the industry. Our mission is to empower every crystal grower to achieve this important milestone.Dr. Ivan Orlov obtained a Ph.D. in Crystallography from the Federal University of Technology in Switzerland EPFL and an MSc in Solid-State Physics in Moscow, Russia. Ivan co-founded Scientific Visual in 2010 to answer the challenge of the synthetic crystals industry struggling with high defect yield. Prior to this he worked in a company specialized in diamond optics. He has more than 10 years of experience in R D with focus on optical materials, industrial crystals and non-destructive quality control technologies. Dr. Orlov was a SEMI Task Force member for sapphire standard development in China and collaborates with ISO committee in Switzerland to establish industry-wide sapphire quality standards.Serena Brischetto is senior marketing and communications manager at SEMI Europe.
