While many pioneering women in STEM have made significant contributions to science and technology, they have not been given equal recognition for their work. Following is a short list of some of the many women who have been trailblazers in STEM and had an impact on the microelectronics industry.

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.

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.
