Brewer Science

More than 400 students from disciplines including electrical and computer engineering, materials science, physics, and business registered for the inaugural Semiconductor Day at Ohio State University.

5 main challenges to fulfill the B Corp mission: establishing documentation processes, connecting with other Certified B Corporations, encouraging engagement among employees, supporting social and political initiatives, & providing a pathway to other Missouri-based Benefit Corps.

The semiconductor industry – recognizing its own fabs can do much more to reduce their carbon footprint – is in a position to help turn the tide on rising temperatures worldwide and more chip companies are launching sustainability initiatives to contribute to the cause.

Today, AI algorithms are primarily run at large data centers-- in the cloud. For this intelligence to be used at the edge, data must be transmitted to the cloud, analyzed there, and the results transmitted back to the field of operation, such as a mobile phone, medical implant or autonomous vehicle.

Becoming a Certified B Corporation™ comes with many benefits, most of them extending beyond the walls of the company and into the hands of employees, community members, and industry partners. The designation makes the meticulous and rigorous process to certification well worth the endeavor. In 2021, Brewer Science announced that it’s the first company in the semiconductor industry to become a Certified B Corporation. Our journey to become a Certified B Corporation inspired us to share our top five reasons for meeting the high standards the designation sets for both environmental and social responsibility. 1. Pave a pathway for continuous improvement B Lab™, the certifying organization for B Corps, believes in continuous improvement, and B Corps must create an improvement plan to demonstrate the areas of social and environmental performance they focus on in the coming years. Brewer Science will hold B Corp certification for three years before submitting to a renewal process. In order to be recertified, a company must score higher on recertification than on the previous certification. The assessment evaluates all facets of the company, and it’s a learning process to help the company target and identify ways to improve business practices. Brewer Science has already identified improvement areas for the recertification. We’ve implemented several human resource initiatives that are not written into policy yet, such as flexible and expanded work options. Additionally, we have expanded our use of a cloud-based learning platform to provide employees with more training options and performance conversations held quarterly instead of annually. Brewer Science scored many points for community involvement and charitable giving. However, we are still expanding community engagement by supporting or donating to a new local organization each month. Brewer Science became Certified Employee-Owned in 2020, but since it was the first year of the ESOP and shares were not yet dispersed, B Lab didn’t fully recognize the program. 2. Share the values of your stakeholders In 2006, Brewer Science started externally reporting environmental, safety, and health performance every year through its annual Corporate Sustainability Report in order to be transparent with customers, suppliers, and employees. The impact of this report on all of our stakeholders motivated us to pursue other ways to promote sustainability and inclusion as a shared asset for our customers and suppliers. In 2016, Brewer Science became GreenCircle Certified Zero Waste to Landfill, an annual certification that we have achieved every year since then. Certified B Corporations are businesses that meet the highest standards of verified social and environmental performance, public transparency, and legal accountability to balance profit and purpose. The standard is highly respected standard, in part because of B Lab’s rigor with the questionnaire and certification process. Not only does becoming a B Corp show your stakeholders that you care, and that you are walking the walk, but it also allows you to show how much your company cares through your B Corp Impact Area. Brewer Science pursued the impact area of environmentally innovative manufacturing, a category that required detailed evidence of how Brewer Science manages the manufacturing waste and minimizes its carbon footprint. The B Impact Area Scores reflect the five areas where the business excels. 3. Be competitive in an industry that demands sustainability and social responsibility Sustainability is of growing importance in the semiconductor industry. A company can convey its commitment to sustainability by becoming a Certified B Corp. The B Impact Assessment requires benchmarking to other companies in the industry in areas of social concern, such as sustainability, inclusion, and diversity. While benchmarking was nearly impossible for Brewer Science since we rank high as an innovator in these areas, we were able to not only set the benchmark for ourselves, but other industry partners who pursue B Corp certification in the future through our collaboration with B Lab. 4. Connect with a community that cares Becoming a Certified B Corporation instantly opens companies up to a network of other B Corps across the world. The more than 4,000 B Corps in 150 industries and 74 countries enables makes it easy to network in the areas such as environmental initiatives, attracting top talent, and even just using business as a force for good in the semiconductor industry. Knowing that a business is actively trying to make a positive social change will help attract top talent looking to find meaning in their careers. B Corp certification validates a company’s employee-centric culture, which can help beef up employee retention. What’s more, an exclusive job posting board called B Work, sponsored in part by B Lab, helps connect job seekers with companies that share their values. Employees are connected through an exclusive B Corporation community platform, B Hive, enabling them to collaborate and share ideas with other B Corp employees. There is also a section within the B Hive where other B Corps can share benefits with other B Corp member employees. With such a diverse range of companies that are Certified B Corps, shared benefits can include anything from discounted clothing to travel deals or even free consultations. Additionally, employees of B Corporations can collaborate on local recycling events and community engagement. 5. The bottom line Companies don’t pursue the Certified B Corp designation to drive improvements to their bottom line. Yet by sharpening their focus on environmentally sustainable initiatives and diversity and inclusion, most companies could indirectly see significant return on investment. For example, having a pathway for continuous improvement, sharing the values of your stakeholders, being competitive in the industry, and connecting to clientele and employees that value social responsibility all enable your business to grow. In the long run, becoming certified as a B Corp can save a company money by giving companies access to community data that provides insights into cost-effective ways to be more sustainable. Plus, the certification process helps companies identify wasteful spending.

Understanding the significance of a B Corp™ comes down to measuring the success of a company in more than profits and ROI. Can global impact, sustainability, and social justice deliver value to stakeholders too? At Brewer Science, we boldly answered, “yes!” and launched our journey to becoming a Certified B Corporation™. A B Corp is a for-profit, corporate entity that seeks to positively impact society, the community, and the environment, in addition to generating profit. The concept is catching on. Today, there’s a worldwide network of almost 4,000 Certified B Corporations across 150 different industries and 74 countries. In May 2021, Brewer Science announced that we are the first company in the semiconductor industry to become a Certified B Corporation. As a chip industry trailblazer for this certification, Brewer Science wanted to share a little about its journey and answer questions often posed by its suppliers, customers, and competitors: Why would a company go through the exhaustive auditing process, how does it work, who does it involve, and what comes next? Why did Brewer Science seek to become a Certified B Corporation? Certified B Corporations are the forefront of a growing global movement of people using business as a force for good™. Certification demonstrates a spirited commitment to high standards of social and environmental performance, transparency, and accountability. “Certified B Corporation standards align with our mission of being a company of the people, by the technology, for the customer, to achieve fulfillment,” said Dr. Terry Brewer, Founder and CEO of Brewer Science. “Becoming a Certified B Corporation exemplifies our commitment to our mission to continuously evolve our global footprint to the benefit of our employees, community, and customers, adding unexpected value throughout the world.” Certified B Corporations are held accountable for environmentally friendly business practices, being inclusive, and promoting local businesses. Besides providing a social benefit to our suppliers, customers, and employees, the certification also gives Brewer Science extensive opportunities to grow the business in collaboration with other mission-driven companies and people. For example, as Certified B Corporations, companies can attend the B Climate Collective and work synergistically with other B Corp companies to advocate for social change. How did we become a B Corp? Brewer Science completed a meticulous assessment process conducted by B Lab™, which examined over 170 factors in reviewing Brewer Science’s customers and vendors, record of inclusion, community involvement, corporate governance, and environmental impact. B Lab also analyzed average employee tenure, charitable giving, energy savings plan, recycling policies, employee volunteer service, and employee upward mobility. The process of becoming a B Corp begins with a self-assessment that the company’s Board of Directors must certify and ends with a 90-minute review call during which B Lab reviews the company’s responses and the company presents supporting evidence. The entire process is rigorous, with the company winning and losing points based on various criteria. These points are factored into weighing its strength as a candidate, and also in identifying opportunities where the company can improve. B Corp status is granted when the company earns at least 80 out of 200 points. But, this is just the starting point of an ongoing process of growth and improvement to uphold the values of the B Corp into the future. The assessment is more than a scorecard. It’s a thorough inspection of every facet of the company and helps guide it in making changes, since every question in the B Impact Assessment must be supported by an explanation and real-life example. A key part of the certification requires choosing a Business Impact Area, which requires the company to prevent evidence of processes it has implemented to influence that area. This component counts for 29 of the 80 points required to achieve Certified B Corporation status. Brewer Science pursued the impact area of environmentally innovative manufacturing, requiring us to provide detailed evidence of how we manage waste in manufacturing and minimize our carbon footprint. We earned an Overall B Impact Score of 88.7. Brewer Science also addressed other areas in the B Impact Assessment such as our human resource initiatives, community involvement, commitment to helping underserved communities, and seeking minority-owned businesses–just to name a few. The assessment incudes the five B Impact areas where Brewer Science scored the highest. Who was involved in the B Corp process? Brewer Science assembled an internal B Corp task force team of directors from departments across the company to provide a cohesive and complete view of the company – a step that was necessary for us to meet the requirements of B Lab’s extensive auditing of the company. B Lab encourages the use of an outside consultant that serves as a liaison between the company and B Lab. Brewer Science’s internal B Corp task force team held bi-monthly meetings with its consultant for nearly a year to answer the hundreds of questions in the questionnaire and gather evidence to corroborate each claim. “It’s a very extensive, but very rewarding process,” said Karen Brown, Project Manager at Brewer Science, also known as the B Keeper by B Lab since she led the certification process within the company. "B Lab is very thorough with the process. It is detailed with what it means and what the questions stand for. It is firm with its requests to ensure that the certification is taken seriously.” What’s next on Brewer Science’s B Corp Journey? Brewer Science’s B Corp certification is valid for three years, at which we point we will apply for renewal – a process that will require us to score even higher than on the previous certification. B Lab stresses continuous improvement, and B Corps must create an improvement plan that spells out areas they will enhance in the coming years. Brewer Science has already identified improvement areas for the recertification. Several of our new human resources initiatives – such as flexible and expanded work options – have not yet been committed to policy. Additionally, we have expanded our use of a cloud-based learning platform to increase training options for employees and hold performance conversations quarterly instead of annually. As part of the assessment, Brewer Science won points for community involvement and charitable giving. However, we are expanding our community engagement by providing employees with a monthly charity or cause to support. Brewer Science became a Certified Employee-Owned company last year. Since 2020 marked the launch of our employee stock ownership plan (ESOP) and shares had not yet been dispersed, B Lab didn’t fully recognize the program. These are just a few examples of how we plan to earn more points during the recertification. At Brewer Science, we hope we can inspire other industry leaders to apply for certification.

Tracking and quickly diagnosing COVID-19 infections, working from home and telemedicine recently came into sharp focus as technology executives and other subject matter experts from microelectronics heavyweights recently gathered for the first-ever virtual SEMI CTO Forum to explore how the microelectronics industry and their own companies can leverage future technology trends to drive growth. Themed Intelligent Medtech and Wearable Technologies, the forum drew CTOs from ARM, Babblelabs, Brewer Science, Dell, Dow/Dupont, E-Ink, Hewlett Packard Enterprise, Intel, Lam Research, KLA, Microchip, ON Semiconductor, Qualcomm, Tokyo Electron, Ulvac, Veeco and Xilinx. The event is designed as a strategic driver of pre-competitive innovation. Following are key takeaways from the forum. Microfluidics Promises to Speed COVID-19 Diagnosis More than 240 companies worldwide are developing microfluidics solutions to improve diagnosis and treatment of COVID-19 and other conditions, said forum speaker Dr. Kurt Petersen, a member of Band of Angels, Silicon Valley's oldest angel investment group, with an illustrious background1 in technology. And their innovations are bearing fruit. Cepheid, a company founded by Dr. Petersen, has developed a disposable microfluidic cartridge, Xpert Xpress SARS-CoV-2, used by doctors to swab the inside of a patient’s mouth. Highlighting the vital role of MEMS in medical electronics, the tiny powerful devices are behind a test that can detect COVID-19 infection in under 40 minutes. Dr. Petersen also cited a few examples of implantables and injectables under development, including: In vivo chemical sensing: Profusa developed a continuous glucose monitoring sensor via an optical patch. Glaucoma pressure monitors: Injectsense built a silicon chip the size of a grain of rice that is embedded in the eye to measure eye pressure. Retinal implants: Second Sight implanted a 60-electrode array chip that projects images onto the retina to improve vision. Microelectronics Takes Aim at Battling COVID-19 The event’s CTO roundtable, a platform for discussing societal and technology issues, revealed microelectronics technology will likely give rise to solutions for combatting pandemics and new business opportunities both in the short and long run. Areas of the greatest interest included: Tracking and Security: Infection tracking accuracy is key to limiting the spread of viruses yet comes with inherent privacy and security challenges. The consensus view of the executives was that developing trusted hardware capabilities is critical for adoption of accurate infection-tracking technologies. Remote Operation: Executives expect working from home or the use of telehealth to continue building momentum long after pandemic. To give staying power to the remote communications at the heart of these trends, microelectronics ecosystems will need to boost compute performance, both at the edge and in the cloud, while increasing bandwidth to enable applications such as augmented reality/virtual reality (AR/VR), artificial intelligence (AI), machine learning and advanced data analytics. Edge intelligence: The challenge of remote communications spans both people and the Internet of Things (IoT). Questions persist about how hundreds of billions of sensors will connect to the cloud and how much power they will consume. The need to push computing to where data is generated – at the edge – is rising and the necessary underlying technologies will only come by combining various forms of distributed computing and analytics. The microelectronics industry’s ability to seize these opportunities will only be possible with huge strides in innovation, raising concerns among the CTOs about the financial viability of cutting-edge devices because of increasing device complexity and R D costs. Technology partnerships and collaborations – an area where SEMI is contributing and will continue to expand its efforts as it works with the CTO community – will be critical to containing R D costs. SEMI will help the executives identify and mobilize the resources key to future innovation. Improving Home, Work Productivity and Experiences Key to AR Adoption Smart wearables also offer great promise. In just over a decade, AR and VR have grown from science fiction to practical uses such as AR applications for smart contact lenses, said Dr. Mike Wiemer, Co-Founder and CTO of Mojo Vision2. Dr. Wiemer said that while many AR applications remain under development, the technology will only see widespread adoption once it starts to improve productivity and efficiency at home and work and the quality of other experiences. The smart augmented reality contact lens developed by Mojo Vision is a step in that direction. The product’s built-in display gives users timely information about everything they see while remaining invisible by packing 70,000 pixels into a space smaller than a half a millimeter across, making it the smallest and densest dynamic display ever made. The contact lens is powered by an ARM-based processor, with later versions adding an image sensor, eye-tracking sensors and a communications chip.

Flexible hybrid electronics (FHE) is innovation and modern technology at their best, giving rise to lighter, more malleable sensors that better conform to the human body while breeding new applications across a number of markets. For the semiconductor industry, FHE technology is enabling the development of a new generation of chips with the high performance, light weight, scalability, softness and flexibility usually seen in printed electronics. The technology is a boon to chipmakers, giving them novel ways to innovate for the Internet of Things (IoT) market.“The global printed electronics market is expected to garner 14.9% GAGR from 2018 to 2023,” said Stanley Wong, Director of Asia Business Development, Brewer Science, said in his presentation at FLEX Taiwan 2019 in late May. Representatives from industry, government, academia and research institutions gathered at the event in Taipei to explore flexible electronics innovation and growth opportunities.One shining star of FHE innovation is the foldable smartphone. So bright is the future of the bendable devices that not even recent trade tensions between the United States and China have dimmed prospects for the fledgling industry.“While the US-China trade war might slow down shipments of Huawei’s phones, the industry remains bullish on foldable phones,” said Stacy Wu, Principal Analyst at IHS Markit. “When the first generation of flexible AMOLED displays was launched in 2016, the rolling radius was 3mm and it could be folded 200,000 times.”For foldable phones, the 200,000 mark was a major milestone – the industry’s consensus standard for foldable phone display reliability. The industry reasoned that phones capable of being folded and unfolded 200,000 times without distorting color or images or the display itself cracking was a safe bet for consumer adoption. Earlier this year, both Samsung and Huawei announced foldable phones using the thin-film-display technology, ushering in the era of mass-market availability of the devices. Steve Chiu, Division Director for Electronics, IC package, Industrial Technology Research Institute (ITRI), believes that breakthroughs in the next generation of flexible AMOLED technology will allow thin films to be folded 100,000 times with a rolling radius up to 30mm and electric resistivity of less than 10 percent. The rolling radius of 30mm, 10 times higher than today’s phones, will give foldables a higher bending radius, while the lower electric resistivity will help maintain the brightness of the AMOLED panel after tens of thousands usages and extend the service life of foldable smartphones.The biggest challenge facing the foldable phone industry remains developing new materials that are flexible yet durable, stressed Francesco Lemmi, Business Development Director, Flexible Display, at DuPont. Today, the prevailing practice is to layer polyimide (PI) and hard coating on the display module. These stacked protective films replace traditional glass panels but present technical challenges related to impact resistance and the durability of the display as it is folded and unfolded over time.Smart clothing market is another hot market, with 33 percent global growth annually and revenue expected to reach US$ 3.26 billion in 2026. Yet for all the promise of smart clothing, reliability and accuracy remain a big challenge chiefly due to a lack of industry standards. Another gap is the unanswered question of whether consumers will embrace light and energy-efficient products.FLEX Taiwan 2019 speaker Satoshi Maeda of Toyobo is confident they will, pointing out that in the future consumers will enjoy a wide selection of comfortable smart clothing products and applications. The industry is still working to better understand how to develop human-machine interfaces, the essential seam between the human body (the outer layer of skin) and electronics, said Dr. Reinhold H. Dauskardt of Stanford University. Still, he sees great promise in an innovative somatosensory communications platform involving human skin. Human-computer interactions have historically been defined by human touch and vision (for example, typing at a computer keyboard and checking our monitor for the accuracy of our inputs). Dauskardt believes that, in the future, electrical impulses from the skin (conductance) will interact with signals from electronic devices to establish a more intimate human-machine interface that could be adapted one day to extend the visual and auditory abilities of humans.David M. Yeung, co-founder and CEO of Lionrock Batteries, pointed to another challenge in wearables: battery size. Today, large and heavy batteries account for 50 percent to 70 percent of the space in wearable devices, making many of the products too cumbersome to wear. Nanofiber lithium-ion batteries now under development can be as small as ultra-thin 2mm with a rolling radius of up to 20mm in radius and support for high electrical currents, significantly lightening their weight and improving comfort.Nardev Ramanathan, Lead Analyst, Digital Health and Wellness at Lux Research, predicts that, of all flexible electronics products, smart watches will win the largest market share and with the fastest rate of adoption. The devices will get a boost when they shrink as flexible batteries are integrated with the bands. The next wave of smart wearables will feature devices for exercise or medical monitoring. Already, FHE materials have led to advances in medical devices. One example is that smaller hearing aids are now possible thanks to flexible electronics and dressings used to promote skin regeneration, reduce wrinkles and remove scars.Gillian Ewers, VP Marketing at PragmatIC, sees fertile ground for FHE applications in IoT solutions. As FHE manufacturing costs drop, she believes IoT technologies will significantly deepen their penetration into a broad range of industries. For example, the number of electronic tags used in convenience stores worldwide will exceed 100 billion in 2025. Thinner than human hair and more durable than traditional wafers, these tags are expected to spawn a host of new business opportunities. FLEX Taiwan attracted more than 270 attendees from more than 30 fields including smart healthcare, e-paper, displays, system integration, automotive electronics, textiles, wearables, and avionics. On the first day of the event, industry, academia and research center representatives from the United States, Japan, China, Singapore and Taiwan gathered to discuss common goals on a range of FHE-related issues and deepen cross-regional cooperation. Like the FHE industry itself, SEMI-FlexTech remains focused on the future by strengthening cross-border cooperation to help manufacturers find killer applications and test profit-making models. For Taiwanese companies, the event will continue to provide insights on market trends, equipment, materials, advanced manufacturing technologies, product applications and new business opportunities, helping the organizations hone their competitive edge in the global market.Emmy Yi is a marketing specialist at SEMI Taiwan.

SEMI’s annual FLEX Conference Exhibition returns to Monterey, California, February 18-21, 2019, bringing together nearly 100 speakers on the major developments at the leading edge of printed/flexible/hybrid sensors and electronics technology.The maturing technology for smarter sensors, in a wider range of flexible formats, is enabling new opportunities across a wide range of applications, from healthcare to agriculture. And that means sensor suppliers need to connect with a broader range of users to build the next generation of innovative outside-the-box solutions. SEMI gathers the flexible/hybrid integration supply chain, leading researchers and potential customers at this annual event to help advance the sector.Collaborative efforts for sensors emerging markets: global health, faster crop development, military monitoringThere’s huge potential for smarter, more accessible sensor systems to detect infectious diseases and aid decision-making for community health workers around the globe, but new technologies and manufacturing methods alone will not be enough to meet the needs of these resource-constrained environments, argues Arunan Skandarajah, program officer at the Bill and Melinda Gates Foundation. He’ll introduce the foundation’s funding and partnering priorities for sensing and imaging for diagnostics and decision support and discuss potential paths forward for development.Recent advances in plant genomics and high-throughput phenotyping have big potential to enable faster development of crop varieties that better withstand adverse conditions – but that will depend on getting fast feedback from sensor data from the field. There’s immediate need for robust, high-efficiency, low-cost sensor technologies to collect on-the-ground microclimate and resource-use data from tractor-based sensors to field scanners, says Nadia Shakoor, Danforth Plant Science Center. She’ll discuss the sensors researchers need to develop high-yielding, energy- efficient crops that are resilient to variable climates.Military interest in biosensor patches to monitor human physiology and performance, and other sensor solutions for flexible imaging and point-of-care diagnostics, are also drivers of collaborative research between industry and universities. The Nano-Bio Materials Consortium (NBMC), a SEMI strategic association partnership with the Air Force Research Lab, will offer a workshop to discuss its potential needs, and how to get involved in its development program to create an integrated suite of nano-bio materials and production technology. Progress in scaling printed/hybrid flexible electronics manufacturing technologyThe maturing manufacturing supply chain continues to make progress towards scaling volume manufacturing of higher performance products, with recent innovations in materials and assembly technologies.Cal Poly researchers will report results from the recent FlexTech benchmark study of the flexible hybrid electronic industry. The study looks at the current state of maturity of the technology, its manufacturing processes, and its main applications while projecting the roadmap for future development.

The Advanced Lithography TechXPOT at this year’s SEMICON West will explore progress in extreme ultraviolet lithography (EUVL), its economic viability for high-volume manufacturing (HVM) and other lithography solutions that will address the march to 5nm and onward to 3nm.As a prelude to the event, SEMI asked Mary Ann Hockey, director for Advanced Emerging Lithography at Brewer Science Inc., and a speaker at the TechXPOT, for insights into the status of directed self-assembly (DSA) as it applies to the industry’s march to patterning for the 3nm node and beyond. For a full list of speakers and program agenda, visit http://www.semiconwest.org/programs-catalog/lithography-5nm-and-below.Mary Ann Hockey, director for Advanced Emerging Lithography at Brewer Science Inc.SEMI: What is the current status of materials development for DSA?Hockey: We are currently working with strategic customers to implement high-quality DSA chemical material solutions. We are both addressing near-term implementation of standard PS-b-PMMA block copolymers (28-30nm Lo) by leveraging our strategic partnership with Arkema, France, and building a library of high-chi block copolymers for long-term device requirements (Figure 1). SEMI: How do those developments prepare the technology for 5nm, 3nm or beyond?Hockey: We have engaged the strategy of engineering a library of novel high-chi block copolymer (BCP) platforms for next-generation DSA technology requirements of 3-5nm devices. One key objective is a global focus on easing implementation into a manufacturing environment. This objective requires large process windows for guided alignment (accommodating pitch and guide size target variability), minimizing BCP microphase anneal times (short anneal time supports high throughput), and streamlining the total number of process steps required for volume production (Figure 2).SEMI: How will industry’s use of DSA be intertwined with immersion lithography?Hockey: We envision immersion lithography as the foundation enabler with strategic use of optical lithography for generating consistent critical dimension (CD) sizes of DSA guides/templates for low cost of ownership.SEMI: What about the combination of DSA and extreme ultraviolet lithography (EUVL) to fabricate devices at 5nm, 3nm, and beyond?Hockey: EUVL and DSA can potentially work in harmony to support next-generation device technology. DSA can be made with the capability of lithography rectification or enhancing EUVL photoresist sidewalls and targeting low line-edge roughness and line-width roughness (LER/LWR) values.Debra Vogler, SEMI
