Find the entire series here.Chip traceability. It’s one of the next big things for the technology industry. The benefits are enormous, and the upsides — which include enhancing yields by identifying the sources of reliability issues, fighting counterfeiting, and growing the overall technology market by enabling new applications — are plentiful.But the implementation challenges of chip traceability are also big and will require considerable effort to overcome. Perhaps the biggest hurdle of all is that we need to transcend industry fears by demonstrating that we can secure IP when it is shared across the hardware supply chain. What will drive the technology industry to make the necessary investments in traceability? “Automotive will drive traceability,” asserted Doug Suerich, product evangelist at PEER Group and an active participant in the SEMI Standards Traceability Committee. “If I had to guess, the autonomous car in particular will drive a traceability-standard effort.”Where Reliability is CriticalWhen your laptop crashes, it’s annoying. But when a car crashes because of a system failure, the damages can be severe and catastrophic It’s also one that is poised to get exponentially larger as we see ever greater amounts of silicon content in vehicles.Fortunately, everyone can agree on the nature of the solution. The industry needs to create a standard for traceability throughout the supply chain. When lives are at risk, we must find and fix the manufacturing source of any defects that affect reliability. That’s understood. Now it’s the not-so-small matter of figuring out the details.Of course, it’s not just about cars. Manufacturers and users of medical devices and military platforms also put a premium on extended, high levels of reliability. In the technology industry, however, the automotive market represents such enormous growth potential that we view it as integral to future industry success.At a market size of more than $1 trillion, automotive is steadily becoming a high-tech market as cars transform into advanced technology platforms that offer partially or fully autonomous features. Vehicles are fast becoming semiconductors on wheels. With leaders from Google to General Motors investing heavily in chip advances, the automotive industry will demand a supply chain that requires chip and device traceability from all its participants.The SEMI Technology Communities and Standards Committee have made some inroads toward solving the traceability challenge with their development and publication of a SEMI Standard enabling traceable device-level identification (ID) throughout the IC manufacturing, test, and assembly processes to the point of use in the final system. The standard is a meaningful first step but overcoming the challenges of counterfeiting and information sharing remain and will require greater industry collaboration.“It comes down to a safety issue,” said Suerich. “We need the ability to collect data across the supply chain, so we can trace down the source of a reliability issue, analyze the data and take corrective actions around applications for which safety is critical. Automotive, medical and aerospace devices need to keep working over five, 10 or even more years. For the semiconductor industry, that means redefining yield.”Traceability Roadmap“It’s going to be a major challenge to share data throughout the supply chain, not just technologically, but culturally as well,” added Suerich. “It will take a concerted effort, and we’re just in the early stages of figuring out some of the IP protection issues.”While traceability is new ground for the culture of the semiconductor industry, the automotive industry has long embraced tracing the sources of defects. In some cases, automotive suppliers have issued wide-ranging product recalls due to safety concerns. The Takata airbag defect, for example, resulted in tens of millions of recalled airbags. As the automotive and semiconductor supply chains increasingly overlap, SEMI committees and task forces are in an ideal position to model traceability best practices in after those implemented by the automotive industry.“We’re going to need an organization like SEMI to coordinate and organize this,” observed Suerich. “While we’re still in the early phases of figuring this out, the market potential around automotive has attracted a critical mass of powerful companies who want a solution. We need to standardize a way to tag which information can flow up and down the chain, and which is protected. I think we’re looking at more than five years of hard work around new standards.”Semiconductor companies are understandably cautious about sharing data related to their proprietary processes because the value of the intellectual property and need to protect data is simply higher than in many other industries. “Automotive offers the perfect confluence of factors to drive traceability in semiconductors,” Suerich concluded. “There is increasing silicon content as well as lives and big money at stake, and motivated players at leading companies and within government institutions want to see progress.”Use your voice to affect standardization in and around the microelectronics industry.

This article is the first in a series highlighting the vital importance of SEMI Standards to commemorate the publication of the 1000th SEMI Standard in July 2019. Find the entire series here. More than 40 years after establishing the SEMI International Standards program, SEMI recently announced its 1000th SEMI Standard – a safety guideline for handling energetic materials. Creating a resource for unpredictable changes in materials is the type of challenge the SEMI International Standards program is often called upon to tackle – where the standard is merely the end of the beginning. The semiconductor industry has learned to expertly control its facilities, equipment and components. The next logical step is materials. It’s common knowledge that the industry drives innovation with new process materials and enabling safer material exploration is critical to the industry’s success. Classification Schema The 1000th SEMI Standard provides three classifications of energetic materials and byproducts based on three criteria: Hazardously exothermic (large amount of heat released following a trigger event such as heating or a physical shock) Pyrophoric (self-igniting upon air exposure) Water-reactive (releasing a large amount of energy or flammable gas upon contact with water) Unsafe handling of any of these byproducts can, to put it mildly, result in a bad day for a fab or lab. The leader of the Energetic Materials Task Force and an expert in process and equipment risk assessment at his company Safety Guru, Eric Sklar recounted one of the stranger incidents. A cleaning crew detached a pipe from a piece of equipment associated with a process recipe that used no energetic materials. The team set it in a sink, sprayed some water to begin cleaning it, and the pipe ignited in flames. Remarkably, although the initial materials weren’t energetic, the process created new byproducts that were very much so. Standardizing on Shifting Ground Energetic materials are new ground for standards and that ground is shifting, with much more material innovation to come. The upshot is that it is particularly important that the energetic materials standard is dynamic. By design, all SEMI Standards are malleable – continuously shaped by the demands they aim to meet. The release of this document is nowhere near the end of the work, as the standard will evolve to keep pace with continuing materials innovation. Creating a Robust Materials Supply Chain SEMI Standards create the conditions for a more robust materials supply chain and sustain the needs of business. If the standards safeguards are too burdensome, they will never be adopted. Conversely, without protections, people and equipment are unnecessarily put in harm’s way and innovation slows. SEMI’s Energetic Materials Task Force members realized early on that the industry needed a standard that would be practical to implement and flexible enough to be optimized over time. They understood that collaboration and compromise, while time-consuming, are also essential for standards’ creation. They determined roles and responsibilities across the supply chain, and they struck delicate balances between sharing no information about the intended uses of potentially dangerous materials and sharing everything about proprietary process recipes. The sheer scope of this standard necessitated a multi-year timeline. “The effort began with SEMATECH assembling its members’ views about energetic materials safety,” said Eric Sklar. “It then required years of effort from SEMI to bring the key industry participants together to create pragmatic guidelines that address the challenges around energetic materials in the supply chain.” Only Getting Started Despite all the work, one certainty is that the standard isn’t perfect for the present and can’t reflect future demands. This is why the energetic materials standard is not a static document, but a living process that is in its germinal stages. Key players continue to shape the standard, and that’s fundamental to enabling future materials innovation and ultimately reducing the number of unexpected energetic materials reactions in fabs. The variables in standards development are numerous and ever-changing. Energetic materials only magnifies the need for the broad collaboration that SEMI has facilitated for more than 40 years. While the risks posed by energetic materials are substantial, the criticality for continued innovation is undisputed. Now, with its adoption, the work of adapting and modifying this 1000th SEMI Standard is only about to begin. Use your voice to help drive standardization in and around the semiconductor industry.

Post-Conference Report: SEMI Heterogeneous Integration SummitDemand for high-performance computing (HPC) chips is exploding. These super-speedy chips are critical for data centers and cloud computing infrastructures to support new performance-hungry technologies such as artificial intelligence (AI) and 5G. The challenge is for the devices and their multi-core architectures to couple high bandwidth density with low latency and high energy efficiency. Heterogenous integration offers a potential answer as an advanced packaging technology designed to meet these skyrocketing performance demands on HPC chips and open the door to a whole new world of 3D integrated circuits (ICs).So important are 3D ICs that Intel and TSMC representatives speaking at the recent Heterogeneous Integration Summit hosted by SEMI Taiwan in Taipei declared that the packaging technology will all but dictate the future of the industry. All told, 12 speakers from government, academia and a broad range of leading international companies from sectors including advanced packaging, design, manufacturing, silicon photonics, equipment and materials shared forward-looking strategies, the latest technologies and potential heterogeneous integration market opportunities. Koushik Banerjee, vice president, TMG, Assembly, and Test Technology Integration, at Intel pointed out that using heterogeneous integration for a single SiP (system-in-package) will deliver what the industry has long wanted by enabling multiple process nodes, more diverse silicon IP (intellectual property) and chip functionality, and chips that pair low energy with high frequency. Intel plans to announce its first Forveros 3D packaging product combining a 10nm HPC chiplet with a low-energy 22nm base die and stacked with memory on top. When asked about the future of advanced packaging technology, Banerjee said it will be very much about the combination of Foveros and its very own Embedded Multi-Die Interconnect Bridge (EMIB).For its part, TSMC, will continue to upgrade its CoWoS (Chip-on-Wafer-on-Substrate), InFO (Integrated Fan-out) and other 2.5D IC production solutions while developing 3D chip stacking technology such as SoIC and WoW (wafer-on-wafer). TSMC is ushering in a new age of 3D IC packaging, said Marvin Liao, Vice President, Backend Technology and Service Division, at TSMC. The company’s SoIC is based on Chip-on-Wafer concept, with the flexibility to support one-to-many or different process nodes, whereas its WoW integrates two wafers with solid yields that could be used for products of the same size or manufactured with mature process technology.Speakers also included representatives from ATOTECH, Lam Research, SPIL, Sigurd, Cadence, Grand Process Technology, ITRI (Industrial Technology Research Institute), Industrial Development Bureau, and Lee San-Liang, Distinguished Professor, Department of Electronic and Computer Engineering at National Taiwan University of Science and Technology all shared their perspectives on equipment, materials, and testing and how different industry value chains might contribute to the development of heterogeneous integration technology.Expected to be a key driver of the next wave of semiconductors, heterogeneous integration and related technologies – including 3D IC, FOWLP (Fan-out wafer-level packaging) / FOPLP (Fan-out panel-level packaging), silicon photonics, Micro LED, compound semiconductor, automated optical inspection and SLT (system level testing) – will be a key focus at SEMICON Taiwan 2019, September 18 to 20 in Taipei. The Heterogeneous Integration Innovation Zone – along with featured international programs such as SiP Global Summit, Strategic Materials Conference, the Smart Data Summit and the Smart Automotive Summit – will gather key industry players to reveal the latest technology breakthroughs and market trends.Emmy Yi is a senior marketing specialist at SEMI Taiwan.

In 2016, the then-Secretary-General of the United Nations, Ban-Ki Moon, stated “Saving our planet, lifting people out of poverty, advancing economic growth. These are one and the same fight. We must connect the dots between climate change, water scarcity, energy shortages, global health, food security and women’s empowerment.” The SEMI Talent Forum, 2-3 May, 2019 in Bristol, UK will explore new opportunities and challenges of the digital era and the industry’s need for talent and the knowledge and skills in automation, computerization and digitization to drive tech innovation. Serena Brischetto of SEMI spoke with professor Michael Czerniak, Environmental Solutions Business Development Manager at Edwards, about how digitalization impacts all these key areas and will be instrumental in helping humanity shape the future. SEMI: The preservation of the global environment and the talent shortage are probably two of the most critical challenges confronting the semiconductor industry. What is the Edwards position on these issues? Czerniak: When I started in the industry, climate change was a new concept and scientific investigation was in its infancy. Now it is a well-understood phenomenon and its impacts will only be minimised by the implementation of better technologies, nearly all of which depend on digital technology and a talented workforce to drive new innovation. This is mission-critical not only to Edwards, but also to the digital industry, and indeed our common future.SEMI: Edwards celebrates 100 years of empowering innovative people. How do you help electronics shape the future and advance life standards? What is your secret recipe?Czerniak: Edwards plays a key role in enabling semiconductor manufacturers by making the electronic circuits, also commonly known as chips, on which the Digital Age is built. Our secret recipe is: nothing! We literally have no molecules at all, i.e. vacuum, which enables the intricate processes like plasma chemistry taking place. Those are the processes used to sequentially deposit and remove the thin films that constitute a modern semiconductor device. We also remove harmful and global-warming gas exhausts from these processes to minimise the environmental impact of this amazing industry.SEMI: What is stimulating about semiconductors and could you give us an example of how Edwards is helping remove harmful and global-warming gases?Czerniak: I work in environmental science both at Edwards and also here in Bristol in the School of Chemistry. My least-favorite gas is called CF4. Not only is it thousands of times more impactful as a global warming gas, but also it has an atmospheric lifetime of 50,000 years. Using abatement technology pioneered by Edwards, emissions of this gas into the atmosphere produced by this industry, have been reduced by up to 95%. That’s certainly something to make you feel good about after a day at work!SEMI: Edwards was honored with the SEMI Diversity and Inclusion award and also for the company's 100th anniversary at the Industry Strategy Symposium (ISS) Europe in Milan in early April. What is particularly exciting about Edwards?Czerniak: Edwards is and always has been a very inclusive place to work, not least because it is a global company, reflecting the scope and geographical reach of the semiconductor industry as a whole. This provides a great variety of career paths locally at one of our many global manufacturing sites, or on a global scale, as we need to be where our customers are.SEMI: What are your expectations regarding the forum in Bristol, and for the future ahead? What is the status of the semiconductor workforce development scenario in your opinion? What can we do more?Czerniak: My main hope for the Talent Forum in Bristol is that the profile of the semiconductor industry will be raised amongst students considering their future career options to the point where they seriously consider applying for positions in this field. This applies to students from all disciplines as they are all needed to help develop the Digital Age, and more events like this can only help spread the message about the exciting opportunities and challenges available.Michael Czerniak started his professional career in the semiconductor industry with Philips, initially in the company’s UK R+D labs and subsequently in the fab in Nijmegen, Holland. He then held marketing roles at UK-based OEMs Cambridge Instruments, VSW and VG Semicon before joining Edwards 21 years ago. Michael has authored numerous published articles and patents, co-chairs a SEMI standards committee, participates in the IRDS, is a UK PFC expert on IPCC and has authored chapters on Vacuum and Environmental issues in the Semiconductor Manufacturing Handbook. Michael became a Professor in the School of Chemistry at the University of Bristol in September 2018. Serena Brischetto is a marketing and communications manager at SEMI Europe.

Semiconductor, electronics and equipment manufacturers today face a number of logistics and supply chain challenges that could be overcome by systems providing a secure, tamper-resistant, single source of truth. Chief among these challenges is limited data sharing due to data security barriers among suppliers, shippers, manufacturers and test houses, an impediment to achieving optimal product quality and regulatory compliance. Additionally, inefficient and inadequate processes for tracking goods make it more difficult to isolate shipping problems, track faulty parts and verify product authenticity. Counterfeiting has become a serious problem that costs US-based semiconductor manufacturers $7.5 billion annually.How Blockchain Can Help Clear Data Sharing BottlenecksBlockchain functions could help alleviate many data sharing pain points in manufacturing. Blockchain’s distributed functionality, bundled security measures, and associated features such as smart contracts have the potential to help manufacturers quickly trace goods, manage records transparently, and automate supply chain processes and payments. No isolated blockchain platform would solve all of these problems on its own. But, when combined with other solutions and applied to particular use cases, blockchain has the potential to optimize operations and foster an environment of trust and collaboration among consortium members. Three core features of blockchain make it a valuable technology for manufacturing: Distributed and immutable system of record. With a distributed system of record in the blockchain network, there is no "central" data store controlled by one organization. The distributed ledger provides all participants with a view into the data, thus increasing transparency, data distribution timeliness, information sharing, and data access. Security also improves as there is no single central data store open to external attacks. Once data is inserted onto the chain, it cannot be easily changed. Security and Trust. Blockchain integrates best-of-breed cryptographic mechanisms to guarantee the digital identity of the network participants and secure the privacy of the data stored to enable role-based data access. It brings trust to a potentially trustless environment without the need for a centralized third party. Smart Contracts. Smart contracts are embedded business logic that can be added to a blockchain. They enable the automation of many processes and the secure handling of contracts. Blockchain Use Cases in ManufacturingIn each stage of manufacturing, blockchain could be applied in a variety of use cases to expedite processes and alleviate security issues. A few examples that merely scratch the surface of what may be possible follow.In pre-production, manufacturers may implement blockchain solutions for Collaborative Planning, Forecasting and Replenishment (CPFR). These systems monitor inventory levels, enabling suppliers to replenish supplies before they run low. The expensive, proprietary B2B networks used today could be replaced with blockchain as the common sharing protocol, using non-proprietary or public networks.Suppliers may also combine blockchain with IoT sensors on shipping containers to provide a tamper-resistant record of shipping conditions. This could be used to ensure that temperature and humidity tolerances for chemicals and equipment are not exceeded during transit from the supplier. The identity and materials in components and subcomponents of manufacturing equipment could be collected on a blockchain to verify compliance with environmental and health regulations. During production, a manufacturing process machine can be registered on a blockchain with a unique identity; its performance and maintenance history can be recorded. A maintenance service provider could then be automatically notified, via a smart contract, when a predictive maintenance alert is written, allowing repair of machines before they fail. In the distribution stage, customers could search the ledger for a product’s complete history, reducing counterfeiting and solidifying the origin of properly sourced goods. When faulty product is identified, the manufacturer may search the ledger to quickly locate the faulty supplier or bad test results and alert all receivers of the defective product.ConclusionWith blockchain, manufacturing can become a more collaborative process among suppliers, manufacturers and customers. Blockchain can help streamline the supply chain and inventory replenishment, improve tracking and regulatory compliance, and reduce counterfeiting. Augmenting blockchain with IoT enables use cases like predictive maintenance and monitoring of goods during transit. Blockchain is not yet mature and its business value still needs to be proven. However, it is poised to help manufacturers decrease costs and fraud, and provide customers with faster, more secure delivery, increased visibility, and consistency.More Resources on Blockchain and ManufacturingTibco is an active member of SEMI’s Smart Manufacturing Technology Community, which holds regular meetings on this and other topics.

SEMI met with Jay Zhang, business development director at Corning Incorporated, to discuss recent innovations at Corning that allow fine granularity CTE engineering as well as high Young’s modulus. We also talked about the impact of this work on in-process warp control, as well as the associated production methodology that provides rapid prototyping and high-volume manufacturing. We spoke ahead of his presentation at the 3D Systems Summit, 28-30 January, 2019, in Dresden, Germany. To register for the event, please click here.SEMI: What is Corning’s mission and vision and your role within the company?Zhang: Corning is one of the world’s leading innovators in materials science with a track record of 165+ years of life-changing innovations. We excel in glass science, ceramics science, and optical physics and succeed through sustained investment in RD E. Our products include Corning® Gorilla® glass, a durable material used on more than six billion mobile devices worldwide, and industry-leading LCD glass for display applications. We have recently dedicated a unit of the company called Precision Glass Solutions to address the emerging need for glass in the semiconductor industry. Here we apply Corning’s long history of glass science expertise and deep customer relationships in consumer electronics to support cutting-edge applications like wafer-level optics for precise 3D sensing and carrier solutions for temporary bonding applications in semiconductor manufacturing. It’s our most recent work in the Carrier Solutions product line that I’m excited to present: a new carrier glass product optimized for fan-out, called Corning Advanced Packaging Carriers.SEMI: What projects are you currently working on that you think will make a difference in 2019?Zhang: My team is excited to introduce Corning Advanced Packaging Carriers this year. This is a new line of product within our portfolio of Carrier Solutions. These ultra-flat glass carriers are specially developed to reduce customers’ challenge of in-process warp by up to 40 percent, which in turn helps advanced packaging customers achieve better yield.Corning Advanced Packaging Carriers feature high-stiffness properties and are available in a wide range of coefficients of thermal expansion (CTE) in fine granularity. These attributes help customers select an ideal glass carrier that will minimize in-process warp for their package. Furthermore, we make sample quantities of these carriers available in just four to six weeks to help maximize efficiency during customers’ R D process.My team is excited about the potential of this new product, but also encouraged by our results. We have already supplied this product and have heard from one of the largest semiconductor companies in Taiwan that it has reduced in-process warp by as much as 150μm.SEMI: Your presentation at the 3D Systems Summit will focus on Agile Manufacturing of Glass Carriers for Advanced Packaging. What exactly will you be sharing?Zhang: There is a lot of interest right now in using glass as a carrier substrate in temporary bonding applications in advanced semiconductor packaging – especially in fan-out processes. We also know that in-process warp is a significant challenge to companies pursuing advanced packaging because different CTE materials are added during the process. My team has done a lot of work to understand the impact that an ideal CTE glass carrier substrate can have on minimizing in-process warp. We have studied the available levers – both theoretical and in real-life fab environments – that can help address this challenge. I will present our findings on how it is possible to select a glass carrier with the ideal CTE and Young’s modulus to reduce in-process warp by up to 40 percent, and how Corning has developed an agile manufacturing platform to support customers with these ideal carriers from their R D stage through mass production.SEMI: What do you think will be a hot topic in the next few years?Zhang: We expect high-end fanout technology to address more applications beyond just mobile APs. There is also an interesting dynamic playing out between wafer-level and panel-level fan-out technologies. Corning is active in both areas. In developing and offering high performance glass carriers, we hope to help enable our customers to expand the fan-out applications space.SEMI: What are your expectations regarding the summit in Dresden, and why do you recommend your members and other industry leaders to attend the 2019 3D Systems Summit?Zhang: Europe is where some of the most advanced packaging technologies are born. Fan-out also saw early commercialization there. I hope to meet many scientists and technologists at 3D Systems Summit and exchange technical and business ideas. We also hope to get early feedback from other attendees about the value of our new product offering. Serena Brischetto is a marketing and communications manager at SEMI Europe.

SEMI met with Erez Halahmi, vice president at 0eC SA, to discuss a new way to transfer information not only between chips but also between servers to reduce power consumption while boosting performance. The two spoke ahead of his presentation at the 3D Systems Summit, 28-30 January, 2019, in Dresden, Germany. To register for the event, please click here.SEMI: What is Zero energy connection’s (0eC) mission and vision and your role within the company?Halahmi: Prof. Naaman of the Weizmann institute of Science (Israel) and I founded OeC SA and invented the Zero energy connection (0eC) technology. OeC SA offers a completely new and innovative solution for interconnections, which dovetails with the current technological trend of “less is more.” In fact, we constantly search for a reduction in energy consumption in favor of capacity, all while simplifying manufacturing processes. We try to look at things differently. This is why our technology is so out of the box. It is a completely new way to transfer information, not only between chips but also between servers.SEMI: What projects are you currently working on that you think will make a difference in 2019?Halahmi: I am working on several diversified exciting projects including the development of a planar field emitter and a rechargeable battery with energy density higher than 1KWh/Kg. Planar field emission is a field emitter made with standard FAB processes that enable a pixelized matrix of emitters at the resolution of photolithography. The rechargeable battery is a novel battery type that delivers unprecedent energy density.SEMI: Your presentation at the 3D Systems Summit will focus on a new way to transfer data. Why is this a key topic?Halahmi: Metals have been used to transfer data since the realization of the first integrated circuit by Jack Kilby in 1958. What happened next? Photonics slowly entered the market supported by huge investments, and the global market grew over the years. However, even with such enormous growth, photonics is not easily integrated with CMOS processes and the market also faces the conversion energy issue on top of the rising costs of process change. Integrating photonics with CMOS requires converting an electrical signal to a photonic signal and back. This costs energy and adds circuitry complexity. What to do? We identified a need to create something out of the box – on one hand using the same CMOS processes without conversion, and on the other hand significantly increasing performance. More details will be released at my presentation at the 3D Systems Summit in Dresden. I am certain that you will find our invention very intriguing. SEMI: What do you think will be the main focus in the future?Halahmi: My belief regarding many aspects of our life is that history repeats itself. Look for example at the comparison Gallium Arsenide (GaAs) versus Silicon (Si). GaAs was never able to defeat the simplicity of Si. The same applies to data transfer. However, for a solution to overtake the metal interconnect, it is not enough to offer many advantages, but the same order of production simplicity should apply. Consequently, big companies will continue to focus on metal solutions for transferring data, though some smaller companies might adopt our technology due to its relative simplicity of production and great benefits.SEMI: What are your expectations for the summit in Dresden, and why do you recommend other industry leaders to attend the 2019 3D Systems Summit?Halahmi: The summit is a great opportunity to learn about new technologies and meet the people behind these innovations. It is a unique chance to meet and question the inventors themselves and learn more about your competitors. See you soon in Dresden!Serena Brischetto is a marketing and communications manager at SEMI Europe.

New SEMI Taiwan Testing Committee to strengthen the last line of defense to ensure the reliability of advanced semiconductor applications.Mobile, high-performance computing (HPC), automotive, and IoT – the four future growth drivers of semiconductor industry, plus the additional boost from artificial intelligence (AI) and 5G – will spur exponential demand for multi-function and high-performance chips. Today, a 3D IC semiconductor structure is beginning to integrate multiple chips to extend functionality and performance, making heterogeneous integration an irreversible trend. As the number of chips integrated in a single package increases, the structural complexity also rises. Not only will this make identifying chip defects harder, but the compatibility and interconnection between components will also introduce uncertainties that can undermine the reliability of the final ICs. Add to these challenges the need for tight cost control and a faster time to market, and it’s clear that semiconductor testing requires disruptive, innovative change. Traditional final-product testing focusing on finished components is now giving way to wafer- and system-level testing.In addition, the traditional notion of design for testing, an approach that enhances testing controllability and observability, is now coupled with the imperative to test for design, which emphasizes drawing analytics insights from collected test data to help reduce design errors and shorten development cycles. Going forward, the relationship among design, manufacturing, packaging, and testing will no longer be un-directional. Instead, it will be a cycle of continuous improvement.This paradigm shift in semiconductor testing, however, will also create a need for new industry standards and regulations, elevate visibility and security levels for shared data, require the optimization of testing time and costs, and lead to a shortage of testing professionals. Solving all these issues will require a joint effort by the industry and academia. "With leading technologies and $4.7 billion in market value, Taiwan still holds the top spot in global semiconductor testing market," said Terry Tsao, President of SEMI Taiwan. "When testing extends beyond the manufacturing process, it can play a critical role in ensuring quality throughout the entire life cycle from design and manufacturing to system integration while maintaining effective controls on development costs and schedules. Taiwan's semiconductor industry is in dire need of a common testing platform to enable the cross-disciplinary collaboration necessary for technical breakthroughs."The SEMI Taiwan Testing Committee was formed to meet that need, gathering testing experts and academics from MediaTek, Intel, NXP Semiconductors, TSMC, UMC, ASE Technology, SPIL, KYEC, Teradyne, Advantest, FormFactor, MJC, Synopsys, Cadence, Mentor, and National Tsing Hua University to collaborate in building a complete testing ecosystem. The committee addresses common technical challenges faced by the industry and cultivates next-generation testing professionals to enable Taiwan to maintain its global leadership in semiconductor testing.The SEMI Taiwan Testing Platform spans communities, expositions, programs, events, networking, business matching, advocacy, and market and technology insights.

I really don’t know clouds at all. – Joni MitchellThe semiconductor industry is finally on the cusp of joining the cloud revolution. The cloud has offered the promise of greatly expanded resources for years, but adoption has been slow due to lingering concerns. The biggest contributing factor for the concern over moving from on-premise EDA servers to cloud-based servers is, surprisingly, the rise of third-party IP. In the old days, if you were developing 100 percent of your own IP, and if you put that IP on a public cloud, and it somehow leaked out, well shame on you. That would certainly be bad for business. It might hurt your reputation a bit. But these days, with so much third-party IP being embedded into chips, if that third-party IP leaks out, that’s a lawsuit-fest in the making.Consequently, semiconductor companies now have even more incentive to protect IP with advanced security. Surprisingly, cloud-based security is far, far better than on-premise security. Why? Because keeping customers’ data secure is the central mission of cloud service suppliers, so they’ve developed a rich set of security tools to protect the data that’s entrusted to them by their clients. In many ways, you can maintain much better security in the cloud than you can with on-premise tools. Image credit: Markus Spiske temporausch.com from Pexels Amazon Web Services: Exemplifying the benefits of cloud computingTake Amazon Web Services (AWS) as an example. (Note: AWS is not the only vendor in the cloud space, but it’s one I’m very familiar with.)AWS has developed the concept of security groups – firewalls that you throw up around any network interface to allow only specific traffic into that secured network. You can do that for just one server or for a fleet of servers, in just seconds. Most on-premise server networks won’t let you work that quickly, or as easily, or with such fine control because most such networks lack the security tools to do this.In addition, AWS allows you to encrypt every bit of data stored on and flowing through its cloud-based storage systems. You can encrypt data at rest in on-premise storage but it’s a lot harder to encrypt data flying through the on-premise network. Amazon’s Elastic File System (EFS), a managed NFS file service, offers the ability to easily encrypt NFS traffic on the wire, a difficult feat at best with an on-premise solution.AWS built-in encryption key-management service can rotate encryption keys automatically. The cloud also allows you to have key policies that are easy to implement and maintain.Internal corporate networks rely heavily on perimeter firewalls for security. Perimeter defense just cannot deliver sufficient security against determined hackers and everyone realizes this. We’ve built big, open, on-premise networks that are just not well-suited to implementing adequate security protocols. Trying to retrofit these network architectures with additional security is time-consuming and costly, and it hurts engineering productivity. Moving to the cloud gives you a greenfield opportunity to right some of the wrongs of the past.Continuing with AWS as an example, here are some additional advantages of EDA in the cloud: AWS provides physical security that’s far above and beyond on-premise security. It doesn’t publish the physical locations of its data centers. It also has professional security staff 24/7, keycard access, and additional security features that far exceed typical on-premise physical security. AWS automatically manages security patches and access controls for their managed services such as database services. AWS gives you plenty of security tools to automate security processes, audits, and so forth to protect your data. AWS gives you so much flexibility that you can get yourself in trouble in you are not careful. If you want, you can create the same sorts of security holes that already exist with on-premise networks. You shouldn’t of course, but you can if you’re not thoughtful about things. You just need to hire the right people to implement and maintain your cloud security.Here are five very big differences between AWS (cloud-based) and on-premise server networking: Elasticity: Cloud-based systems enable you to scale up in minutes. That ability has pluses and minuses depending on how disciplined you are. On the plus side, you can quickly grow your EDA infrastructure as big as you want and then shrink it back down when you no longer need the additional capacity. All you need to do is tell the cloud service that you need more capacity and it will bring that extra capacity online for you in minutes – and will charge you for it. (That’s the minus side.) When you’re done, you can turn off the extra capacity (and stop paying for it) with the same speed. If you want to provision more EDA capacity for your on-premise network, you’ll need to beg, borrow, or steal existing capacity from someone else on your network, or you can order more servers, get the vendor to build and ship them, install them in your server room, provision them, and bring them online. That will take months. Fault tolerance: On-premise networks rely on large, monolithic service architectures, which saddle EDA vendors with more than 30 years of technical debt. The cloud operates on a different model, one that’s based on containers and microservices. This is inherently a redundant, fault-tolerant computing model if you write your code correctly. The difference between redundancy in the cloud and in on-premise networks is night and day. There’s no comparison. No private networks can match the available and growing redundancy of cloud systems, which have redundant servers inside of a data center and redundant data centers in multiple, worldwide geographic locations, which protects your data from natural and man-made disasters. Network segmentation: Many semiconductor developers have several design centers distributed around the world and there may be IP in use on a project that cannot be shared with certain geographic locations either by law or by contract. Cloud networks are already set up with automated tools for network segmentation that can enforce geography-specific rules through VPCs (Virtual Private Clouds), which are easy to set up. VPCs allow you to set up subnets with restrictions based on routing tables so that IP management and control become highly automated. Removal of single points of failure: The typical EDA grid configuration has several built-in single points of failure. For example, a central job dispatcher generally runs on one single node. If that node dies, all EDA work halts. The same is true for EDA license servers and for configuration-management and version-control servers. Again, because cloud networks are based on the microservices concept, the cloud simply doesn’t need to have the same single-point-of-failure vulnerabilities that on-premise networks have. On-premise networksTo get these same advantages with on-premise networks, the grid architecture must fundamentally be changed, starting with the replacement of NFS. EDA systems need to replace huge, monolithic file systems specifically developed for EDA with object storage. That's a tall order – one that requires the rewriting of fundamental assumptions that serve as EDA software’s foundation.In the 1980s, 1990s, and early 2000s, small EDA startups appeared to fill gaps in the offerings of the large EDA players. If they succeeded and grew, they’d eventually be gobbled up by a larger EDA vendor. That flowering of EDA startups seems to have damped down. The market has really matured.Next wave of EDA startups to offer cloud-first toolsGoing forward, I expect the next wave of EDA startups will be offering cloud-first tools that are not burdened by three decades of technical debt. They’ll be able to architect their tools specifically for the cloud.We’re starting to see this happen. For example, Metrics, a Canadian EDA startup, offers a pay-by-the-minute, cloud-based simulator and verification manager. Although one job on one cloud server might run slower than a monolithic simulator running an on-premise server, Metrics has architected its tools so that you can throw more servers at the problem, allowing you to run all of your jobs at once. Here, multiple simulation jobs running concurrently on multiple servers will ultimately finish faster than running the jobs serially on one slightly faster on-premise simulator.That’s the kind of innovation that we’re going to see. That’s the future of EDA.Derek Magill is executive director and president at HPC Pros. Derek has 20 years of experience supporting semiconductor engineering functions.

4 Key Takeaways from SEMI Taiwan Member ForumThe rapid development of artificial intelligence (AI) has accelerated the digital transformation in various industries and has now fused with Internet of Things (IoT) to exploit the value of both technologies in reshaping the electronics industry value chain. As it emerges from the shadows of its parent technologies, AIoT is giving rise to new opportunities in manufacturing, healthcare, transportation, and even energy. AIoT is fast rising in prominence as an enabler of key electronics manufacturing process improvements and the creation of add-on value to existing products – both critical to the success of many businesses.SEMI and the SEMI MEMS Sensors Industry Group (SEMI-MSIG) held a technical forum on smart sensing and its applications in AI and AIoT, inviting renowned experts in sensors and edge computing to share in-depth insights into the latest AIoT technologies and applications with more than 100 industry professionals in research and development, marketing and sales. Here are four key takeaways from the SEMI Taiwan member forum.1. Steady Growth for Global Sensors MarketThe global sensors market’s steady growth is expected to expand at a CAGR of 6.6 percent from 2017 to 2023, with Asia driving the biggest gains and automotive leading the segments – including healthcare and education – with the strongest growth. Automotive alone is expected to reach US$34 billion in 2023.2. Integration Critical to MEMS Sensors DesignsWith AI booming, MEMS sensor designs need to drive toward greater integration —not only integrating data collection with sensors, but also streamlining data processing on the backend – making 3D models of today’s MEMS mechanical designs critical. The differences between 3D and entrenched 2D models are dramatic, elevating the importance of specifying manufacturing steps in MEMS designs. As new sensors and applications continue to emerge, companies that develop the most powerful integrated designs will win. 3. Growth of Smart Voice-Control Applications to ExplodeAIoT is also accelerating the development of smart voice-control applications and the rise of new related business opportunities. Just 50 million voice-controlled devices shipped worldwide in 2017, a number predicted to swell to 436 million in 2021 with smart home devices such as set-top boxes and smart TVs the major growth drivers.4. AIoT Eyed to Make Human-Robot Collaboration SafeSafety is an essential feature for human-robot collaboration. Tactile sensing technologies give robots a layer of “skin” with capabilities rivaling human touch. To ensure humans and robots work together safely in work environments, sensors on this layer of skin are concentrated – less than 8mm apart, equivalent to the width of a human finger, with a response time of less than 5ms on contact. More than 4 million robots worldwide are expected to be upgraded with these sensing technologies and are on track for deployment in pilot plants in the next three years.SEMI-MSIG is committed to strengthening connections across all sectors in the MEMS and sensors supply chain, working closely with the industry to accelerate the development of related technologies and applications in both mature and emerging markets.
