semiconductors

The automotive industry is changing. Our vehicles are getting electrified, connected and automated. As this trend is accelerating, it’s having an impact on how semiconductor devices, including MEMS sensors, are designed and qualified for automotive. As automotive semiconductor designers carefully consider product definition, product validation, and long-term reliability, MEMS sensor suppliers are responding to new opportunities created by electrified and automated vehicles by developing inertial measurement units (IMUs) for automated driving as well as battery pressure monitoring sensors for Li-ion EV batteries. The most complex MEMS device of all The automotive MEMS IMU is probably the most complex MEMS device that will be used inside a vehicle. This type of IMU is a System-in-Package (SiP) comprised of multiple gyroscope and accelerometer sensing elements plus a signal processing ASIC, integrated into one package that creates an inertial sensor able to measure up to six degrees of freedom (6DoF): yaw, roll and pitch for rotational movements, and lateral, longitudinal and vertical acceleration for linear movements. Degrees of freedom in a vehicle For vehicles with Level 3 autonomy and above (per SAE definition), the IMU is mandatory for taking over the trajectory control of the vehicle in case other sensors, such as the camera, radar or LiDAR, become impaired. Should such a failure occur, the IMU will function as a guidance sensor to bring the car to a safe stop within a short period of time and distance. The IMU is also used to control the regular movement of the car while driving in automated mode. While IMU technology already exists for aerospace applications, there are significant challenges to adapting it for automotive. The automotive IMU requires high performance at costs that are compatible with the automotive industry. Because automotive life cycles are long, MEMS sensor suppliers must produce the device in high volume for an extended period of time. They must also guarantee the sensor’s performance and reliability over a 10- to 15-year lifetime with no maintenance or recalibration of the sensor required. Only a few MEMS suppliers have the capability and willingness to embark on this kind of journey. Electrification is creating new applications for MEMS sensors The conversion from internal combustion engines to electrified propulsion is going to affect the powertrain MEMS market. For example, pressure sensors used in engine management for air pressure and fuel pressure will simply go away with electrification. However, the use of large Li-ion batteries in electrified vehicles has created a new application for MEMS sensors. One of the known risks of Li-ion batteries is the small probability for a battery cell to go into a thermal runaway situation that will lead to a fire. The press has reported multiple cases of EV batteries catching fire. Thermal runway effects When it comes to thermal runaway events, every second counts. Detecting the event as early as possible enables the vehicle safety system to take all necessary measures to warn occupants of an imminent fire and activate timely countermeasures (e.g., trigger fire extinguisher and call fire brigade) to mitigate the impact of the fire. Published studies have shown that measuring the pressure inside the battery pack is a good indication that a thermal runaway is starting. The outgassing of a battery cell, plus a sudden rise in temperature, will increase pressure inside the battery pack, which will generate a pressure pulse. To detect such a pressure pulse, a MEMS pressure sensor must permanently measure the pressure inside the pack. It must also report to the battery management system any suspicious change in pressure, independent of atmospheric pressure changes. It’s important to keep this kind of sensor on all the time to detect any pressure anomaly in the system, even when the vehicle is completely off. NXP has developed a pressure sensor to specifically address this new safety application in EVs, and several automotive manufacturers are already using this solution. NXP battery pressure management sensor The quest for zero defects While the automotive industry is targeting zero fatalities as its ultimate goal, the semiconductor industry and module suppliers are targeting zero defects for each and every semiconductor device. For safety-critical automotive MEMS sensors complying with the Automotive Electronics Council (AEC) Q100 qualification for semiconductors, it’s necessary but clearly not sufficient to guarantee a zero defects production launch and long-term reliability of the device. To boost the reliability and robustness of automotive sensors, NXP has developed Above and Beyond (AaB), a new methodology that studies advanced reliability and robustness well ahead of the device’s qualification and production release. Based on risk-mitigation analysis, AaB consist of extensive testing, such as test-to-fail, corner lot testing, and new use-case testing combined with advanced statistics, all of which help NXP understand how these different parameters interact with each other. As sensor suppliers must integrate AaB into their project planning, it does add time and cost to the project. The upside is that this early investment pays off as long as weaknesses in the device can be detected and corrected before a production launch. Field failures, on the other hand, can lead to unplanned redesign and requalification of a device. Worst-case, they can lead to a recall campaign that costs a huge amount of money. We’re systematically using the AaB methodology at NXP for safety-critical MEMS sensors because its potential benefits far outweigh its costs.

With IP the lifeblood of today’s globally integrated microelectronics supply chain, protecting confidential information is vital to electronics companies around the world. Additionally, the industry’s central role in ensuring the national security and economic competitiveness of every country ups the ante. Yet the supply chain is fraught with security risks. Malicious actors never rest in their work to infiltrate factory systems or human resources databases with the intent to steal IP, disrupt production or embed malicious software that can open the door to future attacks. Cyberattacks in the financial and retail sectors typically draw much more public attention than IT security breaches in the semiconductor industry. While large microelectronics companies are not immune to these threats, they tend to deploy some of the world’s strongest security systems and implement robust security policies and protocols to help mitigate risks. Many of their small and mid-sized counterparts with modest IT budgets and limited expertise, on the other hand, struggle to maintain a similar level of cyberhealth – a critical gap in the microelectronics industry, one of the most strategically important in the world. SEMI is out to help change that by collaborating with cybersecurity experts to help members strengthen their cybersecurity defenses. SEMI plans to increase cybersecurity awareness within the microelectronics workforce and offer cybersecurity assessments to member companies through a third-party provider as part of its SEMI Works® program. Working with experts, SEMI will add cybersecurity-related competencies to the SEMI Works® Skills Portal database to help ensure educational and training programs address these skills. As part of SEMI’s recently launched Curated Content Initiative, member companies will have access to workforce training courses on how to raise awareness of cybersecurity risks and mitigate them. Strengthening IP protections across smart technologies and industries driving the next wave of microelectronics industry growth such as artificial intelligence (AI), 5G, medtech and mobility starts in chip design and extends through fabrication to packaging and ultimately end-use applications. Helping to establish a baseline understanding and awareness of cybersecurity risks and how to mitigate them throughout the supply chain is critical. Bolstering cyber protections at small and mid-sized member companies is a key step in that direction. Commercial success, national security and the security of the ubiquitous IT infrastructures at the center of how we work and live depend on it.

New treatments for vascular disease. Optimized agricultural production. Beefed up performance of wearable devices and flexible displays. Four students with their sights set on making the world a better place won Innovators of the Future awards at the 20th Annual FLEX Conference in late February after presenting novel ideas for advancing flexible electronics in the popular student poster event. It was clear that all of these young innovators are working on projects with the potential to impact our lives in the near future. Their work is critical to advancing products, devices and basic research in flexible electronics. Posters created by the 17 students who competed for the awards were judged by a multidisciplinary panel of industry experts. The posters reflected a broad range of applications enabled by flexible hybrid devices and covered technology for wearables, medical devices and precision agriculture. Innovators of the Future Award Winners Robert Herbert from the Georgia Institute of Technology won first place for his paper Smart and Connected Stent System with Nanomembrane Soft Sensors for Wireless Monitoring of Hemodynamics. Vascular diseases are the leading cause of death worldwide, accounting for over 30% of all fatalities. Early diagnosis and monitoring blood pressure and flow rates are critical to effective treatment. Herbert’s poster introduced a less costly, less invasive and more revealing (spoiler alert) sensor system that uses a flexible, wireless biosensor system with an inductive medical stent and capacitive pressure sensors. The laser-machined stent uses multi-layered material integration to function as an inductive coil for wireless communication while maintaining mechanical properties similar to conventional vascular stents. The stent and sensor system can be easily deployed using conventional catheter procedures. Watch his presentation. Jose Waimin from Purdue University’s School of Materials Engineering was one of two second-place winners for his poster that shows how real-time monitoring of ion concentration, moisture, pH, microbial activity and other key metrics in agricultural production can optimize crop yields while reducing environmental impacts. His work presented a scalable alternative for manufacturing low-cost flexible sensors that can be used in an array of applications. Electrodes are manufactured in a Roll-to-Roll (R2R) process to enables fast production at a very low cost per device. Watch his talk. Benham Garakani from Binghamton University, Center for Advanced Microelectronics Manufacturing (CAMM) was the other second-place winner for his paper Electromechanical Behavior of Flexible Silver Paste and Highly Stretchable Liquid Metal for Wearable Electronics. Garakani explored how to improve fabrication of reliable, comfortable wearable devices to boost performance and functionality using substrates such as nonwoven high-density polyethylene fibers (HDPE) and thermoplastic polyurethane (TPU). Garakani also examined the electromechanical reliability of screen-printed silver trace on HDPE fibers and stencil-printed liquid metal (Ga-In-Sn alloy) on TPU during isothermal fatigue cycling. Watch his presentation. Sridhar Sivapurapu from the Georgia Institute of Technology won third place for his poster Flexible and Ultra-Thin 30µm Glass Substrates for RF and mmWave Flex Applications. Sivapurapu’s poster addressed the increasing demand for maximizing the mechanical flexibility of flexible displays while maintaining or improving their electrical performance. Sivapurapu focused on both electrical and mechanical properties for determining the viability of ultra-thin glass stack-ups for flexible RF applications by benchmarking the electrical performance of the ultra-thin glass stack-up to 110 GHz. He also examined electrical characterization during bending tests using free arc bending. Watch his talk. The Innovators of the Future award was sponsored by FlexEnable, a technology provider that develops flexible organic electronics technologies and OTFT materials. All FLEX Conference 2021 presentations are available through March 26, 2021 by registering for the event. Gity Samadi is co-chair of the FLEX Conference student poster awards and program manager at SEMI FlexTech.

Despite the pandemic lock-down, demand for electronic products and services remains strong. Work-from-home, video conferencing, and remote learning are driving data center growth and laptop and tablet demand. 5G infrastructure rollout is underway and smartphone sales are returning to normal levels. Automotive sales are increasing. At the same time, the industry is experiencing acute shortages of substrates. The October 2020 fire at Unimicron’s IC package substrate plant in Taiwan exposed the serious nature of the capacity shortage for IC package substrates. Substrate makers have been reluctant to make large investments in capacity over the last few years due to the fear that demand could decline and they would have excess capacity. Relentless price pressures by customers and the resulting low margins have weakened the finances of substrate suppliers. With tight capacity, substrate prices have increased and lead times are 14 weeks or more. The most critical shortage is for flip chip ball grid array (FC-BGA) substrates. In addition to increased demand in units, applications such as servers and networking products are seeing requirements for larger body sizes and increased layer counts. Shortages will not improve very soon because it takes time to build a new plant. And equip it. Key equipment for substrate production has lead times of up to a year. SEMI and TechSearch International detailed the substrate makers and provide projections for the substrate market, trends, and a list of suppliers and their plant locations in the Global Semiconductor Packaging Materials Outlook report. The report also highlights the market and suppliers for leadframes, bonding wire, encapsulation materials, underfill, die attach, solder balls, wafer level package dielectrics, and wafer-level plating chemicals. In times of shortages the report is an important indicator of suppliers in the industry and trends. Jan Vardaman is President at TechSearch International Inc.

Nikki Zaahir joined SEMI last year as senior program administrator on the SEMI Works team after spending the last 15 years designing, coordinating and directing programs that help people develop job skills and find full-time employment. Her career includes roles at the Department of Defense, the National Security Agency, America Works and Vehicles for Change.I spoke with Nikki about her passion for workforce development as we celebrate Black History Month.Williams: What does Black History Month mean to you?Zaahir: Black History Month means to me an opportunity to highlight the overwhelming influence of the inventions that Black Americans contributed to this country. Of all the Black history shared this month, it’s the inventors that have always intrigued and excited me the most. I grew up in a home with parents that taught my siblings and me the history of our culture every day. However, each February I was allowed to research and share my own list of what we called “little known Black history facts.” A couple of my favorites from my childhood are Lonnie Johnson, who invented the Super Soaker water gun, and Alexander Miles, who developed automatic elevator doors in 1887. Frankly, Black History Month reminds me to be proud to be Black and to take a moment to pay homage to the excellence and fortitude of my people.Williams: Where are you from, and where did you go to school?Zaahir: I am from the suburbs of Maryland right outside of Washington, D.C. I grew up in a military family. My father was the first black 1st Sargent in his transportation company. His unit was responsible for transporting heavy artillery equipment around the world. I went to Meade Senior High School on the army base of Fort Meade.Williams: How did you get started in the semiconductor industry?Zaahir: While in the 11th grade, I was actively recruited by a semiconductor company that had recently won a National Security Agency government contract at Fort Meade to make semiconductors for the military.I excelled in English and Science and met the requirements for the work study, which allowed me to spend half of my day in school and the other half at a work study assignment. The company tested a couple of hundreds of students and I was one of the 34 chosen for the career development program. I worked as a technician responsible for the fabrication and processing of the semiconductor wafer. My favorite steps of this process were the spin on glass and gasses chambers in the fab. What lit a fire in me was the realization that there is a whole world of technology opportunities that people like me were unaware of.Nikki Zaahir, in her former role as National Director of Workforce Development and Training at Vehicles for Change, with interns training to be certified automotive technicians.Williams: Did you have any mentors or sponsors who were particularly meaningful as you developed your career?Zaahir: I’ve been very fortunate to be mentored and supported by many people on my professional journey. Peter Cove and Dr. Lee Bowes are a social activist couple who own America Works. They were instrumental in my understanding of workforce development by teaching me that self-sufficiency through gainful employment can change generational poverty. However, the most meaningful people to me are those whose lives I’ve had the absolute pleasure to help change. For example, at Vehicles for Change, I created a social enterprise designed to assist returning citizens (people formerly incarcerated) with training and job placement. In three years, we placed 200 men and women in the workforce with no one reoffending or returning to prison within three years. What made this group of individuals special is that I chose to focus on violent offenders that served 10 years or more in prison.Williams: What motivates you in your work?Zaahir: What drives me is helping people become aware of careers that could not only change their lives but the lives of their families, and waking up every day determined to be that conduit of information and job opportunities.Williams: What is wonderful and challenging about workforce development?Zaahir: Inspiring people to consider educations and careers that may have never been on their minds is the most rewarding aspect of workforce development. To see people who have felt left out of training and employment opportunities due to their backgrounds or lack of higher education take charge and pursue educations and careers that before were only a dream makes this work worth it. On the other side of that, convincing someone who has felt left behind or unworthy of a better life for themselves and their family can be challenging.Williams: Is there a particular story about someone you’ve worked with or helped that you’d like to tell?Zaahir: Eight-time Grammy award winning artist Lauryn Hill of the legendary hip hop group The Fugees once said “In my travels all over the world, I have come to realize that what distinguishes one child from another is not ability, but access. Access to education, access to opportunity, access to love.”I have been blessed beyond measure to work with and help so many people at this point in my career. What I’d like to share is while talent is abundant, access and opportunity are not. That is the story.Williams: What is something unusual about you that people might not know?Zaahir: I’ve studied at the Arthur Findlay College, the world’s foremost college for the Advancement of Spiritualism and Psychic Sciences. Oh! the ghost stories I could tell.Williams: What would you tell young people interested in working in the semiconductor industry?Zaahir: In this industry, you will develop transferable skills for almost any career in manufacturing or production and the ability to make a salary that will provide the opportunity to afford living in safe neighborhoods, reliable transportation and vacations! You can pursue a wide range of skills, training, education and other professional development opportunities in this industry – all while maintaining a healthy work-life balance.Michelle Williams is deputy director of the SEMI Foundation.

Ride the Wave of Smarter Manufacturing The year 2020 sparked a tremendous acceleration in the digital transformation worldwide, driving a sharp rise in demand for semiconductors and escalating pressure on chip factories to reduce manual functions on the shop floor. The mindset of the semiconductor industry saw a remarkable shift as it recognized with heightened urgency the need to deploy data-driven visualization, analysis, scheduling and dispatching solutions to increase automation to improve production speed and efficiency. Amidst the new excitement around Industry 4.0, chip manufacturers are rapidly deploying new technologies including IIoT, big data, machine learning and Autonomous Intelligent Vehicles (AIVs). Yet for many chip manufacturers, the path to building a smart factory is far from clear because they lack an overall digital transformation strategy. Smart manufacturing is a broad concept covering an array of technologies and solutions, making a holistic, mid- to long-term digitalization strategy rooted in the overall business strategy crucial. There are no shortcuts that can move a manufacturer instantly to Industry 4.0. Instead, this transformation is a step-by-step undertaking with a natural evolution. Some Factory Tasks Must Remain Manual – For Now The semiconductor industry has reached a point where manual processes are no longer efficient enough to support mass chip customization and remote operations. The many technological and standardization advances behind automation can help streamline some of a factory’s most labor-intensive tasks including the loading or unloading of machines or lot tracking and data collection while reducing operational costs. Still, some tasks remain very difficult to automate. For example, handling errors and exceptions presents the greatest challenge since some errors are hard to anticipate. What’s more, the cost of automating error handling can be prohibitive. Eliminating Gaps in Connectivity Often, critical data sources aren’t available due to lack of equipment integration, incomplete product quality monitoring or gaps in material tracking. Closing these gaps in connectivity enables the collection of data and provides rich, reliable information for analysis and reporting that can drive continuous operational improvements, optimizations and efficiencies throughout a factory. But keep in mind that data integration alone can be a challenging task. The selection and proper enrichment of relevant data is, in many cases, not just a technical problem but requires a detailed and in-depth knowledge of the manufacturing steps to be analyzed and optimized. Even when data is available, it might be still difficult to make decisions or implement improvements if it is in siloed systems that require manual processes to integrate and translate into useful information. Problem solving at this level is possible but extremely time-consuming. Manual integration is not only ineffective but costly, draining time, human resources and money from the factory. The right contextual information for the data is vital to unleash its potential and make improvements possible. Dispersed solutions cannot control processes because they span functional areas and people, physical and business entities. Backbone software for shop-floor operations that controls all other applications is central to smart manufacturing. Data-Driven Manufacturing The semiconductor industry is expert in data collection and leads many other industries in this area. The problem is often that chip companies use only a fraction of the information they collect for the analysis and insights needed to improve operational efficiency. By comprehensively integrating all distributed data into a single version of truth – in one location where it is always available – companies can make data analysis and problem solving almost frictionless. Keep in mind that data platforms and edge solutions, within the context of manufacturing, will not be adopted as part of a greenfield initiative. Building a solid automation architecture is only feasible and beneficial by deploying new technologies such as machine learning and artificial intelligence (AI). Analysis of historical data provides important context and reveals deviations such as unexpected process time, uncommon material accumulations or issues with material transport. By integrating swift control actions for new data point collected, manufacturing operations can shift from reactive problem-solving to proactive analysis and operational improvements. The tremendous increase in interest and investment in AI for manufacturing automation only became possible with the availability of low-cost sensors that generate huge volumes of data and solutions for storing and processing that at low cost. AI and other leading-edge technologies transform the tedious but critical process of extracting insights from data, making it instantaneous, streamlined and achievable for every manufacturer. The maturity of smart manufacturing hinges on the extent to which a factory is data-driven. This requires foundational investments to improve traceability, connectivity and real-time operations – and finally making sure that data helps us what to do and when to do it. Ricco WALTER is managing director of SYSTEMA Automation in Singapore.

SEMI spoke with Andreas C. Zimmer, Executive Search and Selection Consultant at ZIAN Co industrial consulting and recruitment, about strategies for attracting and retaining talent and promoting careers in semiconductor industry. Zimmer shared his views ahead of his presentation at the SEMI Fab Management Forum, 17 February, as part of the SEMI Technology Unites Global Summit, 15-19 February 2021, an online event. Join us to meet experts from ZIAN Co. and other key industry influencers. Registration is open. SEMI: What makes the semiconductor industry such a great career destination? Zimmer: The semiconductor industry is an interesting world for anyone involved in or just fascinated by high-end technology. But if we think about our mobile phones, personal computers or cars, we should all ask ourselves what technology is behind these devices we use in our daily life. The classical Newtonian physics does not reveal the source of the pixels in our mobile phones or why a navigation system knows where I currently am and how I’m supposed to drive to avoid the traffic jam ahead. The semiconductor industry truly is the technological pacesetter. The technologies and applications developed by SEMI and its members are the multipliers directly impacting our daily life. Moore's law not only affects the development of chips themselves, but also how we use the applications and devices they enable. Think about the size-performance ratio of modern smartphones compared to the first- and second-generation devices in the 1970s and 1980s, or compare today's BMW with one from the 1960s. The problem is that the industry is too hermetic. We perceive a lack of willingness to go out and tell in a generally understandable way what this industry is all about! Everyone knows Apple, Samsung, Nokia, but who, besides the specialists, knows NXP, Infineon, TSMC or LFoundry? Many companies are largely unknown to the general public! So why should a graduate from a technical university choose a company such as Applied Materials, TEL or ASML? During their studies students will inevitably have come in touch with IC or MEMS companies, but do they also know what is behind them? Do they really know the value chain that leads to the end product? SEMI: What can the chip industry do to better attract talent? Zimmer: Our industry is extremely attractive for anyone who is interested in technology and would like to push things ahead, but unfortunately access to this industry is almost reserved to the initiated who, in whatever way, came in touch with the industry at some point. Let me get this straight: This is not a conscious, willful attitude. It is just the result of our industry’s hermetic attitude. In my opinion, there is no overarching, uniform strategy in marketing, communications or advertising to promote the potential of the semiconductor industry to a wider audience. That’s why SEMI and the cooperation of its members in attracting talent is essential. SEMI: What concrete actions do you suggest for attracting and retaining talent? Zimmer: In German there is the saying “Do good and talk about it!” – and this is exactly what should be implemented. It is not enough to place an ad when necessary, to promote something here and there, perhaps to sponsor a chair or to provide a device free of charge. These are certainly all reasonable actions, but rather random and not long-term or strategic. Furthermore, these actions will reach only a relatively small group of people. The industry should organize structured recruitment activities under a long-term plan, over 10 years or even extending to the next generation. This shouldn't be a rigid corset, but rather a guideline closely informed by the chip industry’s technology roadmap and companies across the supply chain. If it is the task of an organization’s board and the management to define the strategic direction and to set specific goals, it should be the task of technical management to ensure that these goals can and will be achieved. However, this will only succeed if human resources is involved from the very beginning and can plan appropriate personnel resources accordingly. Employees retire, quit and change employers. New materials, technologies, applications and processes are being developed and require new, specific knowledge. Market requirements change. All of these components need to be recognized and considered in early planning. SEMI: What is your experience as a consultant? Zimmer: As consultants, we experience how organizations literally fall out of the clouds when the situation within the organization itself drastically changes, because a strategically important colleague is retiring or suddenly leaving the team for whatever reason. Then, quite surprisingly, the question “Where and how quickly can we find the suitable replacement?” arises. Instead, that departure should be considered as a possible development up front in overall talent planning – a plan B to keep in the drawer. Developing and implementing a long-term HR development roadmap, aligned with the technology roadmap, enables a company to anticipate when specific resources are needed, identify the right people and get them onboard without gaps. It is also important to keep your team informed and involved in all decisions and process changes, and to make sure they get the respect and appreciation they deserve. Employer-employee cooperation over the long term only works when the relationship is a win-win for both parties. If an organization sees the relationship as one-sided to its exclusive benefit, sooner or later the worker will be terminated or quit at the expense of the organization. Truly live the statement “Our people are our best and most valuable resources!” SEMI: When should organizations start attracting young talent? Zimmer: The sooner, the better! Communications aimed at attracting future employees should be designed to reach people of all ages and levels of education. For many years, the tobacco industry targeted young people by demographic, considering their age, education and cultural mindset to ensure they perceived cigarettes as cool. The result? Many people became addicted, mostly for life, just because some clever communications expert touched the right spot! Our industry will not attract teenagers like tobacco corporations did, but the strategy is basically the same: arouse the curiosity of your target group and speak their language. A possible scenario: A company starts and establishes a relationship with neighboring technical, middle and high schools by providing equipment, documentation, and employees who serve as teachers or coaches, and organizing guided tours, seminars and workshops in coordination with the school management. The cooperation continues with the university, where the respective chairs are supported and financed. With a little creativity there are endless possibilities! In our day-to-day business, we observe that large, well-known companies such as Bosch and Daimler are practically sitting on the lap of students in key universities and institutes, yet are unable to identify talent very early and bind them to their company. SEMI: How can organizations capitalize on shifting retirement patterns to help narrow their talent gap? Zimmer: The answer to this arises from considerations related to personnel planning in connection with a company’s technology roadmap. If the roadmap is linked to HR plans, you automatically have an overview of the time-critical moments when personnel gaps might arise. Then you can easily close these gaps, for example by arranging the onboarding of a successor for a specific position long before the job holder leaves. Considering notice periods and approval processes, a period of at least two years should be planned in order to be prepared for personnel changes. Of course, much of this varies depending on the importance of the position to the organization and the size of the talent pool. For example, it will probably be easier and faster to hire and train a sales engineer than the successor for a development manager, when you know there are maybe only 10 people worldwide who are, professionally speaking, at his level. And this is equally true for internal promotions: Always keep an eye on your own people and try to discover their greatest talent! Senior people tend to look outside the organization rather than just around the corner. Maybe the right talent is sitting next to you. Stay tuned and talk to your people to implement a strategic knowledge transfer as part of your organizational culture. Another aspect that is often overlooked is the deputy function: We often find functions in organizations that literally have a unique selling proposition. But there is no deputy, no one who can step in case of an emergency, because no other colleague possesses the knowledge and information to take over if necessary. Usually this is not a problem during a vacation or illness, but what do you do if a key job holder suddenly cannot work from one day to the other? SEMI: What is the role played by artificial intelligence? Zimmer: AI is both a risk and an opportunity. A new technology can always mean danger if it is used incorrectly, and I am not talking about job losses! This has always proven to be a mistake in the past. On the contrary, new technologies create new jobs! New technology accelerates communication, creates new platforms for interaction, shortens decision-making processes, and turns the world into a small village. In your interview with David Meyer CEO of Lynceus, he hits the nail on the head: The great advantage of AI in our industry is likely to be the management, handling, analysis and drawing of conclusions from an incredible amount of information at an unbelievable speed. Without AI, information cannot be controlled to this extent, not to mention accurately evaluated in real time. The mastery of these processes and the learning curve that results from them – for example for the determination of quality levels – should set completely new manufacturing standards. SEMI: How can technology unite us? What do you expect from your participation at SEMI Technology Unites Global Summit? SONAR GmbH has been in this industry as a personnel and business consultant firm for 25 years now. We have experienced many pig cycles since 1995 and accompanied our customers through all the ups and downs, only to have learned one thing in the end: The semiconductor industry is unfortunately still too fixated on technology and overlooks the fact that this technology is made by people for people. The EU's latest Pact for Skills, which was presented at end of November 2020 by Commissioners Schmidt and Breton, foresees 2 billion € investment to generate 250,000 new jobs in the electronics industry throughout Europe! In 2013, we aimed to sensitize semi industry executives, managers and CEOs to the importance of human resources to the well-being and success of organizations. It’s vitally important to invest in day-to-day relationships with your employees to foster their careers and address their needs. The SEMI Fab Management Forum will feature leading game changers of semiconductor operations to highlight best practices for achieving sustainable operations beyond 2020 and exploring the latest solutions for smarter tools and smarter processes.

Materials science – a field that includes elements of applied physics, chemistry, and mulit-disciplinary engineering applied to magnetics, metallurgy, ceramics, polymers and silicon – serves as the foundation for technologies that have driven much of the tech sector’s economic growth for the past 50 years. As our devices grow smaller, faster and smarter – while also requiring higher performance and greater energy efficiency – we’re reaching the limits of what can be accomplished with these fundamentals. The technology sector needs renewed research and investment in new materials to help address the challenges we face in a rapidly changing world. Leading TDK Ventures, the investment arm of TDK Corporation, I’m happy to report that a number of young companies have stepped up to the challenge of innovating materials science for the 21st century. In the past 18 months, we invested in multiple startups dedicated to reimagining the basic building blocks of materials science and identifying new ways to push technology forward – in fact, three of them have successfully gone public or been acquired over the last year. This demonstrates not just a renewed interest in materials science research but also highlights the momentum for healthy returns on materials science investments. Or, as I like to say, it’s the return of materials science returns. Materials science at the atom level For high-tech investors, materials science went out of favor the past 10 or 15 years, because investment in software development companies began to deliver very healthy returns in relatively short time frames – often in as little as two or three years. Product development in materials science traditionally requires much more capital and takes a lot longer to generate returns than software startups. Today’s hardware innovators are making it clear that we’ve only begun to scratch the surface of what’s possible in the materials sciences. Unlike 20 years ago, we can develop products like graphene, which consists of a single layer of carbon atoms that is about 200 times stronger than steel and an excellent conductor of both heat and electricity. Nanometer-scale materials like this enable the design of ultra-low power, high-performance components that can integrate multiple functionalities onto very small devices and create opportunities that were impossible only a few years ago. With advances like this, the future of materials science is regaining its luster.

The recent global pandemic redefined well-established paradigms in healthcare. The classic model involving frequent hospital visits is no longer viable due to the risk of contagion. The focus is now on remote and pervasive vital sign monitoring solutions and automated data processing for health assessment. Social-distancing-friendly technologies, such as wearables, implantables, insertables and ingestables that enable long-term monitoring, can help detect medical abnormalities both in individuals and large populations. SEMI spoke with Carlos Agell, program manager and principal member of Technical Staff at imec, about remote vital sign monitoring using innovative form factors and methodologies. imec’s healthcare technology vison for remote care systems will be the focus of Agell’s presentation at the SEMI MedTech Forum, 19 February, as part of the SEMI Technology Unites Global Summit, 15-19 February 2021, online event. Join us to meet experts from imec and other key industry influencers. Registration is open. SEMI: What is driving innovation in diagnostics and what is the role played by the semiconductor industry? Agell: There is a clear need for remote diagnostics triggered by the COVID-19 pandemic. Two examples are respiration monitoring and SARS-CoV2 testing technologies. The fact that some of the more obvious symptoms of COVID-19 are respiratory has revealed a big gap in medtech: the need for low-friction, ambulatory, continuous and pervasive respiratory monitoring solutions. At imec we have been working on bioimpedance-based technologies (from chipsets to smartphone-enabled sensing devices) that can provide feasible solutions in that space. Hence, novel sensing modalities from the semiconductor industry can make a difference when it comes to remote ambulatory respiratory monitoring. On the other hand, SARS-CoV2 diagnostic technologies have become paramount during the health crisis. In this space there is a clear need to simplify, speed up and lower the cost of testing. Additionally, from a practical perspective society needs to prevent virus spreading. imec is spearheading an innovative semiconductor-based solution aimed at simplifying SARS-CoV2 testing by collecting aerosols from subjects’ breath using a silicon-based solution for analysis using the polymerase chain reaction (PCR) method, the gold standard in COVID-19 testing. Determining viral load in exhaled breath is a clear indicator of infectiousness, and detecting subjects with a high viral load is key when developing these rapid tests to facilitate economic recovery. A cost-effective and speedy though reliable SARS-CoV2 testing solution opens up possibilities for its use as gating mechanism (such as testing to allow access to facilities and prior to boarding a plane) to help jump-start some of the hardest-hit sectors in the economy, such as travel and hospitality (hotels and restaurants) by enabling more in-person interactions. SEMI: Please share more about imec’s commitment to improving the healthcare sector. Agell: imec R D is active in the field of remote unobtrusive respiration solutions, which are vital in treating respiratory system conditions such as asthma, chronic obstructive pulmonary disease (COPD) and COVID-19. These solutions rely on a combination of silicon chipsets, sensor integration and algorithms to interpret sensor data. As part of our effort to understand biological fundamentals, imec’s multi-electrode array (MEA) platform for heart-on-chip applications offers unparalleled capabilities to acquire high-density information (4444 electrodes/mm2) to enable extra- and intracellular recordings, electrical stimulation and impedance gauging to study patient-derived cardiomyocytes, cells that make up the heart muscle. imec is developing a rapid, low-cost SARS-COV2 test based on breath analysis (aerosol capture) aimed at a 5-minute analysis. Such tool is a key to economic recovery, and imec is planning large-scale testing of the prototype device at Brussels Airport later in 2021. imec has recently supported spinoffs and external companies that develop social distancing tools for usage during the pandemic. Healthcare is a key strategic area at imec, with multiple departments working on complementary topics, ranging from cell-sorting technologies and multi-electrode arrays, through sensors and systems for non-invasive cardiorespiratory and neurological monitoring, all the way to advanced processing of medical data and tooling for trials. SEMI: How is the pandemic impacting remote diagnostics? What’s new in that field? Agell: The pandemic has accelerated advances in remote diagnostics for healthcare – for example making remote doctor visits possible and launching telehealth into a successful sector. But in my opinion, this is just the starting point. Telehealth doctors will soon need to collect health data points such as body temperature, weight, or blood pressure remotely, the same information they collect during an office visit. Soon thereafter though, doctor’s will need more and more data, sparking the next stage of advances in remote diagnostics as algorithms are developed to analyze sizeable amounts of data. All in all, it will result in a big move from doctor-centric paradigms to more patient-centric solutions. Hopefully that jump will also drive a more proactive approach to health, enabling prevention and keeping people healthy, and leaving behind the era of curing the sick. imec research tools for respiratory monitoring will come in the form of a health patch. SEMI: Besides infectious disease diagnostics, what solutions will enable a paradigm shift? Can you name two global market trends related to the rising need for remote diagnostics? Agell: The paradigm shift in healthcare will be largely fueled by the hyperconnectivity trend. Communications are fast and far-reaching. The pandemic has proven that healthcare, similar to retail, banking, trading and business in general, can also be done partly remotely through a communications line. The need for proof of performance in the case of diagnostics has been proven challenging, due to the highly regulated medical field and the general conservativeness of this market. There is a clear trend underway in which algorithms and automated diagnostics are slowly gaining the trust of the medical community. Trials and regulatory submissions will help here, but the clear proof will be the general trust of the medical community (and general population) in solutions that have been on the market for a while. Similar to what happened with GPS navigation technologies back in the day, it would require a critical mass to reach general acceptance. As far as the healthcare market is concerned, there is a forecast bounce back from telehealth into hybrid models (a mix between in-office visits and telehealth) as a first post-pandemic scenario. Although this is perceived as the best of both worlds, its effectiveness and survival within the market is still to be proven. A clear market trend accelerated by the pandemic is the commoditization of health and wellness features in consumer electronics. A glimpse into consumer electronics venues reveals that watches, smartphones, weight scales and even your office chair or mattress will soon be collecting healthcare information. imec MultiElectrode Array (MEA) chipset SEMI: What is imec’s role in addressing the challenges and trends in healthcare? Agell: As an R D organization, imec offers expertise in the semiconductor, integration, data interpretation, data management and health-specific application domains. Thanks to our experience in horizontal technology and multiple application domain verticals (including healthcare), imec provides solutions to partners that push the boundaries of performance in health-tangential fields such as communications, consumer electronics, automotive and energy. imec is part of big European initiatives aiming to tackle the challenges of the pandemic. For example, we recently started working on the Digipredict project, which aims at early intervention in infectious diseases. We’re working with key players in the research domain within the EU such as École Polytechnique Fédérale de Lausanne, University of Twente and Eidgenössische Technische Hochschule Zürich. Additionally, imec has worked for market leaders in the healthcare sector such as Philips and Biotelemetry (recently integrated in Philips) and can help partners make the next health solution a reality. SEMI: How can technology unite us? What do you expect from your participation at SEMI Technology Unites Global Summit? Agell: I am a big optimistic on this pandemic. I believe technology has played a key role in putting boundaries around damage caused by the global health crisis. Technology does not only unite us, but it arguably saves lives! My personal expectation for the SEMI Technology Unites Global Summit is for us to get a better understanding about how the semiconductor industry reacts to a pandemic and upcoming post-pandemic scenario. I am curious to see if health-related trends emerge, and whether this is a transitory effect. During the last global pandemic, the semiconductor industry was not even existing, so there is no clear precedent for the current situation.

As the Biden administration begins to advance its policy goals through U.S. government agencies, SEMI is eager to work with these new officials and appointees to advance innovation and strengthen U.S. leadership in the microelectronics industry. SEMI President and CEO Ajit Manocha today sent a letter to Commerce Secretary-Designate Gina Raimondo advocating for strengthening American manufacturing, investing in research and development and pursuing multilateral rather than unilateral U.S. export controls. SEMI also “requests Commerce perform a comprehensive review of recent policies and formally seek industry input via publication of a Notice of Inquiry (NOI), giving industry its first formal opportunity to provide its views on these significant regulations.” The letter discusses the importance of how export controls are implemented, advocating that “multilateral controls – where items of concern are controlled by all major producing nations – create a level playing field, maximize effectiveness, and minimize harm to U.S. national security and economic competitiveness. Unilateral U.S. controls over items for which there are comparable non-U.S.-origin items are generally ineffective in supporting national security goals and are likely to erode any technological advantages enjoyed by U.S.-origin items.” Foreign availability of semiconductor manufacturing equipment, materials and design software is an important consideration for U.S. export control policy related to those items. In an appendix to the letter, SEMI provided charts detailing the foreign availability of major types of semiconductor manufacturing equipment and materials. For nearly all items, there are competitive alternatives to U.S.-origin items available from non-U.S. sources. With many semiconductor technologies concentrated in a handful of key exporting nations, the letter encourages a unified approach via a plurilateral export control regime instead of unilateral U.S. controls for these technologies. SEMI provided a framework of issues that need to be considered and properly addressed in negotiating a plurilateral agreement related to semiconductor industry export controls. The previous administration created several unilateral controls that were implemented with little or no opportunity for public or industry comment and which created several unintended consequences. In addition to the request to publish an NOI, the letter asks Commerce to correct unintended controls related to the August 2020 expansion of EAR General Prohibition Three and reduce the backlog of license and classification requests. SEMI is pleased to work with the U.S. Department of Commerce and other policymakers by providing industry data, trends and perspectives to ensure export controls effectively serve national security interests without undue harm to technological development and leadership in this dynamic, globally competitive industry.
