Technology and Trends

A recent survey by a SEMI Environment, Health and Safety working group found that all responding companies had Business Continuity Plans (BCP) in place prior to the COVID-19 outbreak, nearly half had already developed pandemic playbooks and, as a whole, have mounted robust, effective responses to the pandemic.The Business Continuity Plans of the 19 respondents to the survey, designed to speed crisis response and mitigate business impacts, included countermeasures for any threat to company operations including IT, production, finance, public communications and, of course, health and safety.Nine businesses, or 48 percent, had previously established plans for responding to epidemics and pandemics cited the World Health Organization (WHO) among the most reputable authorities for advice on how to prepare for a virus outbreak. Asian companies significantly outnumbered businesses in the U.S. or Europe in having a pandemic plan in place.The SEMI working group launched the survey shortly after it was formed in early March to gather insights into how SEMI member companies are protecting their employees while adapting facilities and manufacturing schedules to sustain production. The working group, which has grown to include 20 members that convene weekly for virtual meetings, consists of companies spanning the global semiconductor supply chain. The survey also found the following: As of late March, 95 percent of companies had implemented a mandatory work-from-home policy for job functions that could be performed remotely. One company reported that adherence to the policy was voluntary but strongly encouraged. At the time of the survey, 90 percent of companies had not considered using electronic tracking devices for employees at risk of cross-contamination. Taiwan has deployed the technology effectively to track confirmed COVID-19 cases and their travel histories. Nearly 75 percent of respondents conduct temperature screening for employees, 84 test visitors and contractors, and about 75 percent use no-touch infra-red thermometers as their preferred testing method. In instances where an employee, family member or close contact is ill but not a confirmed COVID-19 case, 42% of companies instruct the employee to stay home until he or she and family members are both symptom-free for at least 72 hours. For 30% of companies, the employee is invited to stay home for at least 14 days until the worker and family members are symptom-free. Fifty-eight percent of companies offer limited field service engineer (FSE) support to customers based on the circumstances. At 21% of companies, FSEs and equipment installers are working without restrictions if government and customer policies allow. Three companies suspended service activities. Sixty-three percent of respondents allow only critical visitors to enter their facilities after they’ve completed a health questionnaire and their temperature has been checked, while 21 percent prohibit visitors from entering their sites. More than half of the companies maintain production with social distancing protections in effect.

As a leading TCAD provider, Silvaco has very deep SOI roots, reaching back over 20 years. When Oki* pioneered the first FD-SOI chips in 2000 (really? yes!), whose tools did they use? Silvaco's. And those early FD-SOI chips went into Casio's most advanced G-Shock watches in 2005. (Yes, ASN has been covering FD-SOI for a long time!) But note that while those earliest chips used fully depleted architectures, they were on regular – not ultra-thin – SOI wafers, as they are today. [bctt tweet="Deep Roots: When Oki pioneered the 1st FD-SOI chips in 2000 (really? yes! for #CasioGShock) look whose tools they used: @SilvacoSoftware #FDSOI #lowpower #chipdesign #semiconductor #semiEDA" username="@soiconsortium"] When we look at the IEEE Spectrum Digital Library, it’s clear that Silvaco is continuing to be very active in the SOI space. There are 72 conference and journal publications citing Silvaco for their SOI research simulations since the year 2000 and 27 in the last five years. They’ve supported all the SOI evolutions – including partially-depleted SOI up through and including today's FD-SOI on ultra-thin SOI wafers. There are two Silvaco presentations that were given in Japan last fall – they're now on the SOI Consortium website. A Bit More About Silvaco Headquartered in Santa Clara, CA and founded in 1984, privately-held Silvaco is a leading provider of TCAD tools. TCAD (short for Technology-Computer Aided Design) is the use of computer modeling and simulation in developing semiconductor devices and processes. As such, TCAD tools reduce the development cost and shorten the development time. Silvaco also provides a full suite of analog and custom design tools spanning schematic, layout, signoff and variation analysis. The portfolio also includes tools for power integrity sign off, reduction of extracted netlist, and production-proven IP cores for automotive, consumer, and industrial applications. Silvaco provides a full TCAD to custom circuit design flow for vertical markets including: displays, power electronics, optical devices, radiation soft error reliability, analog circuits, library and memory design, advanced CMOS process, and IP development. They have 500+ customers in worldwide, and market leadership in TCAD design solutions for flat panel displays and power devices. Recent SOI Presentations Here's a quick recap of the two Silvaco presentations from the Japan SOI Symposium, October 2019, which you'll find on the SOI Consortium website. (To view the full presentations, however, your company needs to be a member of the Consortium.) Silvaco RF-SOI TCAD Solution was given by Sun Tao, Applications Engineering Manager, Silvaco. Silvaco positions itself as a “cost-effective partner to the FD-SOI community.” And as the presentation title indicates, it's a review of the tools Silvaco offers that support SOI – especially for RF applications. The presentation began with a review of recent updates to their TCAD simulation framework, including the TCAD design flow, Victory Process for speeding up 2D/3D process simulations, and Victory Device for device simulation. Under Silvaco’s DTCO – Design Technology Co-Optimization – flow, semiconductor physics are connected to circuit design, recognizing that each technology has specific requirements that need to be taken into account at every stage of the flow. [caption id="attachment_31635" align="aligncenter" width="589"] An example of how Silvaco Victory Tools Support Detailed Simulations of RF Devices on SOI (Courtesy: Silvaco and the SOI Consortium)[/caption] Tao then continued by showing useful TCAD simulations and analysis of SOI for RF applications. In trap-rich substrate simulations, for example, the Silvaco tools can predict the distortion from the active device, device biasing, and substrate, all of which can be co-optimized using Victory Process and Victory Device. In conclusion, he notes that Silvaco is offering TCAD to custom EDA solutions for predictive and comprehensive FD-SOI design work that can save money before committing to silicon. Platform Infrastructure for SOI-IP Ecosystem was given by Thomas Blaesi, VP of Global Marketing, Silvaco. "The massive use of IP is both an advantage and a challenge," began Blaesi. There are solutions out there, but they are disconnected. Typically SoC/IP designers, IP librarians, and support folks use various systems, while procurement, finance, and legal use others. This is a problem for both the providers and the consumers of IP. Silvaco has a system called Xena that centrally organizes all IP data: it’s an IP repository for tracking accounts, products, contracts, devices, support, compliance, and reporting. One of the first beneficiaries of Xena will be the SOI ecosystem, as providers of SOI IP are already signing on. [bctt tweet="One of the first beneficiaries of the Xena IP repository from @SilvacoSoftware will be the SOI ecosystem, as providers of SOI IP are already signing on. #FDSOI #RFSOI #semiconductorIP" #lowpower #chipdesign username="@soiconsortium"] Beyond the organizational advantages, Xena has patented “finger printing” and “DNA analysis”, so there is a digital representation of each IP on an SoC that cannot be reverse engineered. Each fingerprint contains list of unique signatures of each file in an IP or SoC. A file’s unique signature is created from the entire file content, and that signature is guaranteed to be unique to that content. [caption id="attachment_31634" align="aligncenter" width="591"] Silvaco's Xena Supports Audits of IP Usage in SoC Projects (Courtesy: Silvaco and the SOI Consortium)[/caption] It enhances support for all versions of common design files: hard IP, soft IP, and embedded software. Because it’s enterprise based, it will be particularly useful for large organizations. Fingerprinting and DNA analysis are vendor agnostic, universal, and easy-to-use tools and methodologies for IP lifecycle management, he concluded. -- *Oki's now part of Lapis Semi, btw, which is still active in FD-SOI

For five days in the latter half of March, the pall of the heavy human and economic toll COVID-19 has exacted in China appeared to be lifting. The epicenter of Wuhan reported no new coronavirus infections through domestic transmission. And in an initial step to loosen its nationwide lockdown, China began reversing restrictions on travel within its borders.Now, in another sign of progress, the region’s idled factory workforce is preparing to return to the production lines. Outside of Hubei province, home to Wuhan, most manufacturing workers are expected to be back on the job by the end of this month, with the proportion of manufacturing employees returning to work in Hubei cities except Wuhan reaching 70 percent by then, said Didier Chenneveau, Partner, Supply Chain Practice, McKinsey Company, in a late-March webinar presented by the business consultancy and SEMI.McKinsey is also “seeing evidence of a rebound in demand led by China’s online sales” as rising consumer confidence and a surge in the popularity of work-from-home policies spur strong spending on laptop computers, Chenneveau said.The turnaround stands in stark contrast to the unprecedented drop in demand McKinsey saw across retail and durable goods in China early in the year. Over the first two months, passenger car sales plunged 90 percent, smart phone receipts 40 percent and retail sales 21 percent, leading to what Chenneveau calls a whiplash effect that could disrupt supply chains as manufacturers and shipping companies scramble to meet pent-up demand once a recovery takes hold. As the outlook for China’s factories and suppliers brightens, concerns are shifting to the ripple effect of its deep manufacturing pullback on demand for goods in the United States and Europe. Sharp disruptions to global supply chains caused by labor shortages and knotty logistics challenges have also become worrisome. And while China is buoyed by the prospect of normalizing its workforce and manufacturing capabilities, parts shortages are bottlenecking production. In the United States and Europe, where 60 percent of air freight is carried in cargo holds of passenger aircraft, logistics concerns loom large with the widespread flight groundings. “Logistics must be a priority in any crisis war room because it’s a big challenge,” Chenneveau said.Asia Semiconductor Supply Chain ImpactsIn Asia, the semiconductor supply chain is working to overcome intractable challenges caused by COVID-19 including sourcing raw materials for chip manufacturing and maintaining assembly and test operations, Mark Patel, Sr. Partner Semiconductor Practice Lead, McKinsey Company, said at the webinar. Those problems cascade to foundries and IDMs even as they confront the compounding issue of a shortage of fab operators and engineers. Downstream, the inability to package, test and qualify products risks exacerbating the supply constraints.Patel said another acute challenge is that most semiconductor manufacturers and suppliers are operating under restricted practices, making it harder to sustain engineering activities vital to new product introductions, new process development and capital equipment expansion. In the longer term, the supply chain fallout hold implications for product life cycles and investments in capacity and next-generation technology – factors that analysts will need to monitor in evaluating the economic impact.Returning Workers Key to Economic RecoveryIssuing shelter-in-place orders have been an effective antidote to the spread of COVID-19 but a double-edged sword as nations worldwide sustain the economic blowback. Discretionary consumer spending on items such as automobiles has dropped by 45 percent globally so far this year, business investment has fallen and trade has seen a sharp slowdown, said Sven Smit, Chairman and Director at the McKinsey Global Institute, speaking at the webinar.A lockdown for as little as a month can slash aggregate global GDP by as much as 10 percent, a scenario McKinsey expects to play out in the second quarter of 2020. The drop would be the deepest since World War II and larger than the plunge in the first quarter of the Great Depression, raising the question of how long governments can afford to keep workers holed up at home.“The economic shock is unprecedented,” Smit said. “We’ve never sent people home to not work. Even in World War II, next to the front lines, people were harvesting food.”China offers a potential blueprint for economic recovery. McKinsey estimates that China’s rigorous containment efforts could help its economy bounce back in as little as six months – a V-shaped rebound. Western nations generally have not been as forceful with their containment measures. For them, the fight against the pathogen could be prolonged, deepening the economic damage.Yet even with the best protective lockdowns, a new challenge arises: The longer shelter-in-place orders remain in effect to contain the spread of the virus, the longer the economic impact drags on. “Until the path to return to work becomes clearer, people will not be confident to spend,” Smit said.Confronted with that reality, governments worldwide must strike the delicate balance between safeguarding the lives of people – critical forces of economic growth through consumer spending – and limiting the economic shock. The faster the virus can be brought to heel, the softer the impact to economies around the world. And the stronger the return-to-work protocols in place once COVID-19 has been brought under control, the faster workers can get back to their jobs. Smit believes resolving both issues simultaneously is not only possible but necessary for a return to normalcy.“That’s the imperative of our time,” he said.

On Saturday, March, 21, 2020 the U.S. Food and Drug Administration (FDA) gave emergency authorization to Cepheid, a California company, to sell a new test for rapid detection of the pandemic coronavirus SARS-CoV-2, which causes COVID-19. Cepheid’s Xpert® Xpress SARS-CoV-2 test gives healthcare workers results in just 45 minutes, with less than a minute of hands-on time for sample preparation.Cepheid, founded by Kurt Petersen, M. Allen Northrup and five others in 1996, is well known in the MEMS community for commercializing microfluidic chip-based polymerase chain reaction (PCR) analysis machines. This is not the first time Cepheid has responded quickly to a biological threat; after the 2001 terrorist attacks in the USA, Cepheid was the first to provide rapid anthrax detection capabilities to the U.S. Postal Service, and it still does today.At the heart of all COVID-19 test protocols (see the WHO protocol and U.S. CDC protocol) is the real-time reverse transcription polymerase chain reaction (RT-PCR) analysis technique. In a very simplified description, PCR uses thermal cycling to amplify the DNA present in a patient’s swab sample, and then using fluorescence optical detection, searches for the virus’s specific DNA. The test requires knowing the virus’s genome in the first place; the crucial work to sequence the full genome of SARS-CoV-2 was first published by Chinese scientists for public use on January 10, 2020.While traditional PCR machines take many hours to thermal cycle and reach a result, MEMS-based PCR systems can work much faster. Featuring scale heaters and reaction chambers that have a tiny thermal mass, they create a significantly faster heat-cool cycle, enabling a rapid result in minutes.The first MEMS silicon PCR chip, developed by Northrup et. al. at Lawrence Livermore National Laboratory and licensed to Cepheid (left) and the Cepheid test cartridge today (right). (Source: Northrup MA, Ching MT, White RM, Watson RT, “DNA amplification in a microfabricated reaction chamber,” Transducers 1993, Yokohama, Japan. pp. 924–926.) Research on MEMS-based PCR systems has continued steadily since the early 1990s. Today, researchers have been focusing on developing highly integrated, low-cost systems specifically for point-of-care use. One example of recent research: a team at Korea’s ETRI and Genesystem have developed a prototype low-cost, handheld PCR system having a polyimide chamber and microheater and an integrated CMOS detector for optical readout of results (figure below). Cross-section schematic of the chamber, heating module and integrated optical detector in a portable PCR prototype (left) and integrated test cartridge (right). (Source: DS Lee, OR Choi, and YJ Seo, “A Handheld and Battery-Powered Realtime Microfluidic PCR Amplification Device,” Transducers 2019, Berlin, Germany pp. 1063-1065.) Korea’s quick recruitment of its biotech companies and creation of novel drive-through testing sites helped it to successfully pinpoint its COVID-19 outbreak and to implement control measures. Let’s hope the Cepheid test can be similarly effective.Based on successive epidemics of SARS, MERS and now COVID-19, rapid PCR test machines, enabled by MEMS technology, are becoming essential medical tools in the fight against viral outbreaks. As continued development lowers the cost of such critical equipment, let’s hope we may soon have a PCR machine in every doctor’s office.Alissa M. Fitzgerald, Ph.D., founded A.M.

The seemingly simple act of commanding consumer devices by voice is a choice that nearly 118 million Americans now make every day, according to a recent report from eMarketer, the digital marketing research firm.While the voice interface is convenient for users, its implementation comes at the potential loss of individual privacy. The reason? Always-on, always-connected voice-first devices such as Amazon Alexa and Google Home require a wall plug and an internet connection to powerful cloud processors, making it possible for cloud companies — however benignly — to collect data on personal habits, location and conversation that were never intended for sharing. Move processing to the edgeTo address concerns over user privacy, device designers are attempting to do more of the audio processing within the consumer device, rather than sending users’ voices into the cloud. Moving more processing to the edge is a trend across the Internet of Things (IoT) industry, and not just for voice data but for other types of sensitive or proprietary data as well.Yet designers have realized limited success because the conventional approach to always-listening edge processing is notoriously inefficient: It digitizes and processes 100% of incoming sound data even though up to 90% of the data is irrelevant noise. This digitize-first approach wastes vast amounts of system power digitizing and analyzing the audio signal as it searches for a wake word when there isn’t even speech present, making it impractical for use in small, battery-operated devices.Workarounds don’t workTackling this power issue is critical to keeping private data secure. Unfortunately, it’s also exceptionally difficult. Design engineers have tried workarounds to decrease power consumption in an always-listening system, including duty cycling and reducing the power of each individual component in the audio signal chain that handles the data. The reality is that these kinds of approaches don’t address the root cause of the problem: too much data.To truly tackle the problem, we need to change our approach to a system solution, not a component solution. By moving to a more efficient edge architecture that intelligently minimizes the amount of data that moves through the system, we can focus the system’s energy resources on analyzing voice and not on searching for a wake word in irrelevant noise. Analyze, THEN digitize It’s time to move away from the digitize-first approach that has dominated voice wake-up device architecture since the invention of voice-first applications.Inspired by the way the human brain efficiently filters incoming information, differentiating, for example, a dog bark from a baby’s cry, an ultra-low-power analog machine learning technology is changing this paradigm. For the first time, device designers can use low-power analog machine learning to detect which data are important for further processing and analysis prior to data digitization.Leveraging an analyze-first architecture, a new analog neuromorphic semiconductor platform allows the higher-power-processing components in the system to stay asleep until voice has actually been detected, and only then does it wake them to listen for a possible wake word.Delivering a post-microphone audio chain that draws as little as 25µA of current when always-listening and collecting preroll data, this analyze-first architecture allows designers to extend battery lifetime significantly. That’s the difference between smart earbuds that run for weeks instead of hours or a battery-powered smart speaker that runs for months instead of weeks.More importantly, it’s the difference between the current always-listening devices that indiscriminately record and send all sound data to the cloud, and one that has the localized intelligence to select and send only the relevant data, reducing the user’s vulnerability to the loss of private data.Balance convenience with privacyThe trade-off between making our lives easier and keeping our personal information private is a choice that we are asked to make throughout our day in a hundred different ways. Bringing more audio processing capability to the mobile device without draining the battery is the first step toward delivering more secure voice-first solutions. But to succeed in this effort, we must shift to a bio-inspired architecture that determines which data are important and requires further processing at the earliest point in the signal chain. Once we move to the analyze-first approach, only a small fraction of the tens of zettabytes of data collected by the forthcoming generation of always-on IoT devices will require further processing in the device and in the cloud.A better balance between cloud and edge processing is a better balance between convenience and privacy, and that’s a win for everyone.About the AuthorTom Doyle is CEO and founder of Aspinity.

Ischemic stroke is the leading cause of long-term disability worldwide, affecting over 13 million people each year and costing tens of billions of dollars. Sensome, a French medtech that offers connected medical devices, has developed micrometric AI-powered impedance sensors that can identify the biological nature of the tissue they touch in real-time. Integration of this proprietary technology into a probe to guide medical devices in arteries (a guidewire) has given rise to Sensome’s first product, Clotild®, which recognizes blood clot types in ischemic strokes so clots can be treated faster to improve patients’ chances of a full recovery. The Sensome technology also helps transform the current standard of care in oncology.SEMI spoke with Franz Bozsak, CEO and co-founder of Sensome, about innovative medical technology trends and how microelectronics plays a crucial role.SEMI: When did your adventure with Sensome start? Bozsak: My former Ph.D. advisor Abdul Barakat and I spun-out Sensome from the Ecole Polytechnique in Paris in early 2014 after receiving a 200.000 Euro grant from the French government. We then developed a micrometric impedance sensor that coupled to machine-learning algorithms to identify biological tissues on contact. We are still integrating this sensing technology with existing medical devices in order to create a new category of smart medical devices that provides physicians with relevant insights during their interventions and treatments. These additional insights aim to render healthcare treatments more effective by reducing the risk of complications and the cost of interventions while improving patient monitoring.SEMI: How are strokes typically treated? Bozsak: Before 2014 the almost exclusive way of treating ischemic stroke was by injecting tissue plasminogen activator (tPA) intravenously in order to chemically dissolve an arterial clot. This treatment approach has severe limitations and can only be used in the first 4.5 hours following the onset of a stroke. In 2015, several randomized clinical trials demonstrated the efficacy of a new treatment modality: mechanical thrombectomy.Medical devices that allow a clot to be removed mechanically either using a grid-like structure (a stentriever) or by aspirating the clot using an aspiration catheter completely changed the paradigm in the treatment of ischemic stroke for up to a third of all patients. This new intervention removes the clot in up to 90% of all cases and can for certain patients be used up to 24 hours after the onset of the stroke.Mechanical thrombectomy is now one of the most effective medical treatments in the world. The clinical data gathered over the past years also shows that, in order to maximize the patient’s chances to lead a life free from disability after a stroke, it is not only a question of getting the clot out but also about how the clot was removed. Removing the clot on the first attempt significantly increases the patient’s chances of recovery – the first-pass-effect that is now the objective when treating ischemic stroke patients. And this is exactly where Sensome wants to help since clot removal after several attempts increases risk for patients. SEMI: How did you improve mechanical stroke treatments?We have integrated our sensor technology into a guidewire, the first device to enter a patient’s blood vessels for navigation to the clot. Once in place, the smart guidewire – called Clotild® – guides the thrombectomy device to provide the physician with information on the clot to help the physician choose the thrombectomy device with the highest chances of achieving the first-pass-effect. SEMI: Medical technology has made astonishing advances over the years. How did Sensome develop the micrometric AI-powered impedance sensors?Bozsak: The development of a product like Clotild® would have not been possible five years ago, and many people considered what we wanted to achieve simply incredible. Today, we can answer those same people: We knew it was almost impossible and therefore we just did it. By combining diverse semiconductor technologies, we were able to build the smallest impedance meter in the world. This was then integrated into a guidewire that can be connected via a transmitter to a tablet that serves as the interface with the physician. The guidewire provides impedance measurements that can be analyzed by a machine-learning algorithm, which in turn identifies the tissue in contact with the sensor. A very diverse team of people, collaboration and several different disciplines such as micro-electronics, data science, biology and engineering were required to make this happen.Our ambitious team has been able to flourish and accomplish their ideas in the very stimulating and resourceful environment of the Ecole Polytechnique, while being embedded into the rich and fertile start-up ecosystem of Paris. It is the combination of all these factors taken together that have made our innovation possible.SEMI: What are the main challenges and what are the market opportunities? Bozsak: Bringing semiconductor technology into the medical field is not a straightforward process. The primary hurdle is the simple fact that medical device production volumes are not comparable with consumer electronics volumes and that development cycles are much longer due to regulatory constraints. Both factors are, at first sight, not necessarily compatible with today’s business model of the semiconductor industry. At the same time, this is also a unique opportunity for the semiconductor industry to diversify and expand into a new field – sensors and, in particular, their seamless integration into the healthcare workflow, are a key driver for the healthcare sector of the future. And to achieve this objective, semiconductor technologies are key. What is beneficial, in my opinion, is that the quality standards and requirements of the semiconductor industry are highly compatible with the needs of the medical device industry.SEMI: Are market fragmentation and the high level of regulation making medtech innovation harder?Bozsak: Both are challenging but very rewarding to pursue since the impact on a patient’s life can be profound. Innovation is harder because many stakeholders are involved in ensuring the success of a medical device launch. The involved, milestone-driven, highly regulated process of developing a medical device and bringing the device to the market assures its eventual success. The development process differs very much from those for normal consumer devices. In our case the beneficiary, the patient, is not necessarily the user of the device but rather the physician. The physician is not necessarily the buyer of the device, but the hospital. The hospital is not necessarily paying the device, but ideally the government.The interests of all these stakeholders need to be satisfied to bring a successful device to the market.SEMI: What are your expectations regarding the future of medtech digital innovation? Bozsak: This is the right moment for the medical device and semiconductor industries to come together. The healthcare sector is not low on medical needs for which innovative ideas exist, and the semiconductor industry has many technologies that can enable these ideas to generate solutions. But to make this happen, both sectors need to collaborate. Working together requires both sides to understand their respective needs and constraints. The earlier the knowledge exchange starts, the more powerful the solutions. SEMI MedTech Forum at SEMICON Europa last year was a wonderful opportunity for Sensome to get this discussion going. We are looking forward to continuing the exchange and push the frontiers of the possible further to create the future of digital healthcare.Franz Bozsak, CEO and co-founder at Sensome, obtained a M.S. in Aerospace Engineering from the University of Stuttgart and a Ph.D. from the Ecole Polytechnique in Biomedical Engineering on the optimization of stents. He is a graduate of the Stanford Ignite/Polytechnique business program. In 2014, he co-founded Sensome and has since built a team of renowned scientists, engineers and doctors to realize his vision of connected medical devices. He was named Innovator Under 35 by the MIT Technology Review in 2016. Serena Brischetto is a marketing and communications manager at SEMI Europe.

In the two months since the COVID-19 outbreak in January, the Chinese economy has shifted from shock to ongoing recovery under the guidance of the Chinese government. China has worked tirelessly to restore production at its chip manufacturing facilities, a core strategic industry in the region, and the effort is paying off. Operations at several fabs and OSATs – the domestic semiconductor industry’s chief growth engines – have begun to stabilize.As of mid-March, SMIC had restored its manufacturing lines to over 90% of production capacity and expects to be operating at full bore in the next few weeks, while the company’s R D line has returned to full operation. Huahong Grace reestablished normal supplies of various equipment parts and production raw materials. At Huahong Fab2, 12 new pieces of equipment went online to help increase production capacity, and production at Huahong Fab1 and Huahong Fab3 is now stable. JCET said the company's overall return rate has exceeded 90%. Meanwhile, IDM maker Silan Microelectronics' 6-inch and 8-inch lines maintained 90% production.Production lines at Huahong Group, SMIC, CanSemi, GTA Semiconductor, Samsung (Xi'an) and other mainland China chip manufacturers have been generally operating at normal capacity since the Spring Festival. Lines at YMTC, Tianma, CSOT, and BOE, all in the Coronavirus epicenter of Wuhan, have also returned to normal operations. China’s chip industry is finding its footing, and an impressive host of semiconductor companies are gearing up to participate at SEMICON China 2020, rescheduled to June 27-29. The list includes the major domestic wafer foundries such as Huahong, the major packaging and testing companies such as JCET, TFME, Huatian, and large domestic and foreign equipment companies, among them TEL, ASMPT, DISCO, ULVAC, VAT, ASML, KLA, NAURA, AMEC, Anji, CETC, Sinyang, SMEE, CAS, CANON and SPIROX.DigiTimes, a daily newspaper covering the semiconductor, electronics, computer and communications industries in Asia, interviewed SEMI China President Lung Chu in mid-March about what’s ahead for China’s semiconductor industry. Following is an English translation of the interview. DigiTimes InterviewAs China continues to ramp back up to normal activity, SEMI China is making every effort to hold SEMICON China 2020, a leading international semiconductor industry platform for promoting growth and innovation in China's semiconductor industry supply chain. SEMI China president Chu emphasized that the strong support of SEMICON China 2020 exhibitors and the Chinese government made rescheduling the event to June possible.Chu, a semiconductor industry veteran who has experienced numerous economic and industry upheavals over his career including the SARS shock in 2003, said current global economic uncertainty stems from two black swans – the global COVID-19 pandemic and how long it will take to contain it, and the sharp drop in oil prices triggered by the recent geopolitical dispute between Russia and Saudi Arabia. In China, the government responded with strict containment actions and promoted public awareness of self-isolation, resulting in effective domestic containment as of mid-March. As a major oil consumer, China sees the lower prices as relatively favorable to its economy. Those dynamics should allow China to recover sooner than many other regions, and it could emerge even stronger once the pandemic is contained, despite the current slump in global semiconductor demand, Chu said. Once the epidemic has passed, China is in a position of "turning crisis into opportunity," and the semiconductor industry will recover from the trough, he said. Companies in semiconductor supply-chain sectors face various challenges in restoring normal operations. IC design companies experienced relatively low impact since employees can work from home and most companies are located in major cities in China, where epidemic prevention control is strict. For most chip manufacturers, production has not stopped but is hampered by manpower shortages from restrictions on employees returning to work. IC packaging and testing companies are suffering bigger impacts because of the more labor-intensive nature of their operations. However, all companies in the supply chain will be affected by the decline in demand for electronic products and ICs in 2020. As the COVID-19 threat recedes in China, the region remains unwavering in its commitment to semiconductors as a strategic industry with its continuing efforts to evolve sustainable and reliable localized supply chains, Chu said. Investments in “new Infrastructure” for 5G, the Internet of Things (IoT), data centers, as well as public health services should help drive semiconductor demand for smart applications and devices associated with the new infrastructures as are all powered by ICs, benefiting companies in the global supply chain. The COVID-19 outbreak triggered a slowdown in new factory construction after the Chinese government implemented restrictions on the flow of people resulting in a worker shortage. SEMI has revised downward its forecast of wafer equipment spending in China to just a 3% increase this year.Market analysts revised downward forecasts for 2020 annual global semiconductor revenue growth from 7-10% to 0-5%, while some expect negative growth. The recent COVID-19 outbreaks in Europe, the United States and other regions have created more uncertainty. Declining end-user demand for electronics will drive down spending on upstream equipment for both memory and logic IC device makers. For Chu and his SEMI China staff, the postponement of SEMICON China 2020 has been a “major challenge,” he said. “It is a huge project to communicate and coordinate with the government and to reconfirm with exhibitors and industry leaders.”As a leading industry platform, SEMICON China attracts a large number of global customers and suppliers each year. The major China domestic suppliers, leading foundries and OSATs have confirmed their attendance in SEMICON China 2020. Most key foreign suppliers are planning to staff the event with local teams in case some executives are unable to enter China by June due to travel restrictions if the COVID-19 virus has not been brought under control in the United States, Europe and other regions. To assure the success of the concurrent Forums, SEMI has prepared multiple contingency plans, including live broadcast, video and slide presentations. SEMI will also hold the grand opening session at a larger venue than last year’s event to accommodate more attendees with more sitting distance apart. SEMI will follow government guidelines to implement appropriate public health and safety measures during SEMICON China. "Ensuring the welfare of all exhibitors and guests and providing a safe exhibition environment is SEMI’s top priority," Chu said.Cherry Sun is a marketing manager at SEMI China.

In the future, electronics-related gear including advanced driver-assistance systems (ADAS) will account for a whopping 50 percent of automotive costs. More importantly, with more control of vehicles shifting to automation, the margin of error in component performance and reliability will become vanishingly small as zero defects become the new safety standard.SEMI spoke with Antoine Amade, Senior Regional Director EMEA, Entegris about zero defects as a new collaborative approach necessary to shape the car of the future and the automotive industry.SEMI: The next generation of automobiles will be more electric, autonomous and connected. What is the most pressing next step for automotive players to pursue this goal? Amade: The automotive ecosystem faces many challenges. For example, when cars become autonomous, their interaction with the cloud and the massive amount of data computed simultaneously could be vulnerable to cyberattacks capable of seizing control of the vehicle.Another example is the use of artificial intelligence (AI) as there is a big opportunity to explore and define the right architecture while also meeting automotive quality requirements. The quality challenge will be amplified by advanced nodes. Reliability is also critical since 90 percent of device failures are extrinsic, or unrelated to device design. Today, the top priority should be to eliminate latent defects, those that remain undetected until the product is in use. These latent defects may appear at some future point in the life of vehicle – 1 month, 1 year, 10 years, etc. This is the vital focus of the carmaker and the supply chain.SEMI: With in-line metrology tools reaching their detection limits, how will the industry reduce latent defects? Amade: Minimizing latent defects is now a top priority in semiconductor fabs. However, there is a gap between visible and non-visible defects. Although fabs can detect small defects, human intervention is still needed to manage them. We are witnessing a fundamental shift in the contamination control strategy in auto chip production, from contamination control for yield to contamination control for reliability. The shift is born of the recognition that all particles, regardless of size, and parts per trillion (ppt) concentration levels of contaminants matter, impact both defectivity and reliability. Contamination management will play a key role in enabling the industry to reach parts per billion (ppb) failure rates at the component level. SEMI: How will the industry reach the goal of zero defects? Amade: A sound contamination management strategy that follows three main axes of actions will be one key to reaching zero defects: the ambient air in the fab, the wafer’s environment over its lifetime, and the integrity of the materials in the clean chemical delivery pathway.Contamination management in each of these three areas presents opportunities to limit process variability. The first step in limiting variation is detecting it, which can be difficult when the contaminants causing the variation are hard to identify or caused by an unexpected event. When a contaminant signature can be detected, it leaves clues to its root cause. Careful scrutiny of these signatures can inform a contamination control strategy to eliminate the root cause and reduce overall defectivity.SEMI: What collaborative engagement model do you see as the best for reaching zero defects? Amade: Entegris sees the SEMI Global Advisory Automotive Council (GAAC) as the perfect collaboration platform for the entire automotive semiconductor ecosystem, from car manufacturers to material suppliers. Entegris is also a member of the Platform for Automotive Semiconductor Requirement Across the Supply Chain (PASRASC). Both forums help raise the visibility of key challenges and potential solutions.Collaboration starts with agreement on a definition of automotive based on existing standards and guidelines that must be communicated across the value chain. Another important element for collaboration is standardizing on how new materials such as SiC Semiconductors (silicon carbide) should be used. Entegris plays a leading role in contamination management for defectivity reduction through its New Collaborative Approach (NCA) platform, which brings a new level of knowledge sharing to all those involved in detecting and improving defectivity.SEMI: Can you explain the New Collaborative Approach in more detail?Amade: During the SEMI Smart Transportation Forum at SEMICON Europa, we presented the process and tools we have been developing in collaboration with car makers and are implementing with chipmakers as part of our New Collaborative Approach. Our data-driven tools compare current contamination solutions practices and identify optimization opportunities. A good indicator of the maturity of the ecosystem, the tools allow chipmakers to compare the contamination mitigation practices of peers with their own and identify hot topics for advancing contamination management strategies. Every year, during Entegris Technology Days, we share best known methods, case studies, and review fab processes in order to propose customized solutions. It is all about improving defectivity.Mr. Amade joined Entegris in 1995 as an Application Engineer in its semiconductor business. In his current role as EMEA/NA Sr. Director, Mr. Amade is focused primary on growing the semiconductor business in Europe and Middle East through market strategies, and the management of sales, customer service, and marketing teams. Mr. Amade held leadership positions at Entegris in functions including gas microcontamination market management, strategic account management, and regional sales management. Mr. Amade has a degree in Chemical Engineering from ENS Chimie Lille and is a member of the SEMI Electronic Materials Group and the Global Automotive Advisory Council for Europe (GAAC).Serena Brischetto is a marketing and communications manager at SEMI Europe.
