Silvaco

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

Here is our second post about the SOI Consortium’s Japan Symposium this past fall. This will provide summaries of eight very informative presentations on SOI in IoT and automotive by NXP, Dolphin Design, Leti, Silvaco, Arm, I-fuse and Secure-IC. There’s a lot of content to summarize, so this post is about twice as long as those we usually do. But you’ll want to read right to the end, for sure! In case you missed our previous post on the 5G/RF-SOI presentations given at the Japan event, you can read it here. Our next and final post on the Japan event will cover photonics presentations by Cisco/Luxtera, TowerJazz, GlobalFoundries, Leti, Cadence and Soitec. By way of reminder, the Japan SOI Symposium was a great success, with both days well attended. If your company is a member of the SOI Consortium, you can now access most of these presentations on our website. You can also click on the illustrations in this post to see them in enlarged versions. [caption id="attachment_28106" align="alignleft" width="366"] (Courtesy: NXP SOI Consortium)[/caption] The IoT World Enabled Through SOI - Jon Cheek, NXP Sr. Director, Front-End Innovation For NXP, FD-SOI introduced the ability to easily add different functionalities to the technology node like ULP, eNVM, support for high-voltage and embedding RF. For them, said Cheek, it’s about the range, and with adaptive back bias, you can “get crazy”, so you can really achieve amazing things. In fact, they think they now have the lowest leakage SRAM in the industry, thanks to body biasing. The i.MX 7ULP is finding significant success in wearables. Their “crossover” chips are the latest beneficiaries of FD-SOI with body biasing. The “new normal”, they offer huge improvements for real-time operating systems – which is of course key for edge computing. (As you can imagine, the audience was intently taking notes throughout -- this was a really excellent talk!) It also is great for machine learning, as it is designed to unlock the potential of voice-assisted end nodes. The IP they needed is now available from multiple vendors, noted Cheek, such as Tensilica and VeriSilicon. Another key play will be in visuals for industrial computing. He concluded by observing that the automobile is the ultimate IoT machine, with 10x the amount of code now found in leading edge airplanes. That’s where the i.MX8 and 8X come in. [caption id="attachment_28104" align="alignright" width="323"] (Courtesy: NXP SOI Consortium)[/caption] High-Voltage SOI – Enabling Automotive- NXP Jon Cheek gave this presentation on the second day of the Japan event. Long-time followers of SOI will know that NXP has been excelling in high-voltage (HV) SOI for well over two decades now (including the pioneering work done by Philips, now part of NXP: their EZ-HV SOI patent dates back to 1993). It’s probably safe to say that NXP's SOI-based automotive chips are used by virtually every carmaker on the planet. HV follows well behind the leading edge – it’s currently mostly around 130nm (the limits are related to metalization). Reason #1 it’s on SOI? SOI-based technologies are incredibly reliable, especially in the automotive culture targeting the three zeros (0 emissions, 0 accidents and 0 time wasted). Today’s car manufacturer’s are going to a distributed environment, and SOI still provides a huge advantage, making parts that are smaller, lower power and more reliable – so it drives a lower BOM for automakers.In conclusion, said Cheek, NXP’s leadership through SOI innovation enables scalable solutions, high voltage analog integration, sensor integration, and reliable safe passenger experience. [caption id="attachment_28101" align="alignleft" width="432"] (Courtesy: Dolphin Design SOI Consortium)[/caption] Improving SoC Energy-Efficiency with Dolphin Design Platforms – Nicolaus Gaude, BizDev Product Marketing, Dolphin Design Dolphin has a series of platforms, techniques and IP for increasing speed and drastically improving energy efficiency in SoC design. Gaude introduced their Speed Platforms, which include a Power Management Platform and a Processing platform, both of which make dramatic improvements in energy efficiency. The Power Management Platform keeps control of power management from architecture to design, resulting in a 10x improvement in energy efficiency. The Processing Platform comprises configurable RTL clusters for best-in-class (100x) energy-efficiency. Gaude then turned to the Dolphin’s Adaptive-Body Bias (ABB) IP for breakthrough energy-efficiency with FD-SOI. This is real-time, “on-the-fly” body biasing: the IP does it all. It is silicon-proven on GlobalFoundries’ 22FDX with Arm cores and Invecus standards cells SRAM, with breakthrough energy efficiency. [caption id="attachment_28108" align="alignright" width="363"] (Courtesy: Silvaco SOI Consortium)[/caption] Platform Infrastructure for SOI-IP Ecosystem – Thomas Blaesi, VP of Global Marketing, Silvaco The massive use of IP is both an advantage and a challenge, began Blaesi.

[caption id="attachment_28103" align="alignleft" width="463"] (Courtesy: Leti SOI Consortium)[/caption] Ultra-low power, FD-SOI based IP, in the space of IoT, Health Care, Smart Connectivity 5G – Michael Tchagaspanian, EVP Industrial Partnerships, CEA-Leti This presentation began with a review of the explosion in devices with IoT and related investments, then connected all the ways in which innovations powerhouse Leti is contributing – from the SOI wafer level to the chip level – which is to say practically everywhere! Especially hot topics in FD-SOI included: the roadmap to sub-10nm; CoolCube monolithic 3D; new embedded memories; power amplifiers; Ultra-Wide Range DSP; smart sensing local processing (including haptics, imaging, infrared advanced processing); local processing with edge AI; and spike coding for deep neural networks. He showed information on two always-on/on-demand transmission 28nm FD-SOI IoT test chips that taped out in mid-2019: the Warrior and the Samurai. And finally, he covered silicon-proven IP that Leti has for FD-SOI including power management blocks, lots of RF IP (including low-power RF wake-up), sensor interfaces, clockless network-on-chip and new SRAM technologies. These and more will be covered at the next Leti Innovation Days in Grenoble (June 2020) – during which in parallel, btw, there will also be a European SOI Summit hosted by the SOI Consortium. [caption id="attachment_28099" align="alignright" width="475"] (Courtesy: Arm SOI Consortium)[/caption] FDSOI Enablement for a Total Compute Future – Manuj Rahor, Director Emerging Technologies Product Marketing, Arm Subtitled A perspective on system optimization with Arm FDSOI IP, this presentation reviewed how Arm is enabling system gains through optimization across IP boundaries. This is work happening in the Arm Artisan Physical Design Group (PDG), which provides logic, memory and POP (processor optimization package) IP as well as various products to help ease implementation challenges for advanced nodes. In this case the focus is on Total Compute enablers on Samsung 28nm FD-SOI (called 28FDS) – specifically three building blocks recently launched on FD-SOI. The first is the 128Mb Wide Capacity embedded MRAM (an eNVM to replace eFlash) compiler for storage delivered to Samsung in July `19. It was demonstrated in silicon in the Musca-S1 Smart IoT Device Demonstrator on 28FDS, an energy efficient IoT device with eMRAM secure boot on-chip storage. [Read our coverage from March 2019 here.] The second is a novel design developed with Spin Memory. It recently taped out on 28FDS and is slated for delivery in 2020. Adding an “Endurance Engine to the eMRAM that was delivered in 2019, the ARM-Spin innovation delivers RAM-like performance with increased speed and endurance. What’s at issue here is a change in use cases. Use cases served by eFlash were not written to that often; now with sensors (as in IoT) that continually gather and write data, eFlash endurance is not sufficient. The third is billed as an SRAM replacement compiler. Its MRAM as RAM in A-class systems, with significant energy and performance gains. Again, this is a use-case issue: retention is lower (this is for weeks months, whereas the other solutions are for 10 years). But you can get more RAM than SRAM into the same footprint, so you get a 60% reduction in DRAM traffic and increased performance. Delivery for this is marked as 2020+. [caption id="attachment_28100" align="alignleft" width="294"] (Courtesy: Attopsemi SOI Consortium)[/caption] I-fuse™: A Disruptive OTP Technology – Dr. Shine Chung, Chairman, Attopsemi I-fuse is a disruptive OTP (One-Time Programmable) technology without disrupting a fuse. The goal was a 100x increase in reliability at 1/100th of the cell size and 1/10th the power. It has now been demonstrated in GlobalFoundries’ 22FDX FD-SOI technology for energy harvesting applications. In the OTP IP technologies, explained Dr. Chung, they defied the conventional wisdom of breaking a fuse to maintain a permanent programmed state forever: Attopsemi’s I-fuse™ is actually a “non-breaking” fuse. “I don’t mind to break a fuse, but I do care about breaking a fuse by explosion”, said Dr. Chung. “The I-V curve of programming a fuse beyond the break point actually shows more like an explosion. The anti-fuse OTP also ruptures gate oxide by explosion. On the contrary, I-fuse™ is a disruptive OTP technology without disrupting a fuse.” He concluded, “By using MOS as switches to enable discharging two capacitors, through cell and reference cell respectively, and compare the discharge rates, the resistance in the cell can be determined higher or lower than the reference resistance so as to convert into logic data. The read energy consumed is only 1/100 of the conventional sensing, which is good for energy harvest IoT applications. Eventually most IoT devices will be battery-less.” [caption id="attachment_28107" align="alignright" width="398"] (Courtesy: Secure-IC SOI Consortium)[/caption] AIoT Embedded Security Using FD-SOI – Yan-Taro Clochard, Japan Sales Director, Secure-IC In addition to opportunities, the impact of AI on IoT (aka AIoT) adds new threats to edge devices. Design for security and in-depth security is required, down to the physical layer. For example in automotive, sensors gather data and AI analyzes it – but the enabler is security. The challenge of AI is the increase in data and connectivity with unsecured devices. FD-SOI is a key for Secure-IC’s Securyzer security module: it leveragesFD-SOI properties to secure the AIoT world. It is flexible, and tuned for each customer. Here, FD-SOI enables the creation of physically secure systems, with secure boot and firmware updates, cryptographic services, key management and secure storage.

The SOI Consortium’s Japan Symposium this past fall covered a wide array of topics over two days. The first day was devoted to IP and products for RF and ultra-low-power (ULP) on SOI. The second day covered high voltage and photonics. It will take several posts to summarize all the presentations. In this post, we’ll cover presentations related to 5G. In the next posts we’ll cover IoT/ultra-low-power/automotive and photonics. (BTW, if your company is a member of the SOI Consortium, you can now access most of these presentations on our website.) The Japan SOI Symposium was organized for the 4th time at the Yokohama Landmark Tower (from which there was a fabulous view of Mount Fuji). It was a great success, with both days well attended. The event followed the day after (and in the same location as) Silvaco’s SURGE user event, so there were plenty of opportunities for synergy there. (Samsung Foundry talked about their partnership with Silvaco, for example, and their work together on RF and eMRAM on 28nm FD-SOI.) STMicroelectronics [caption id="attachment_27068" align="alignnone" width="589"] From “5G Deployment Driving RF and SOI Technology Opportunity” (Courtesy: ST SOI Consortium)[/caption] As noted in the ST presentation, 5G standards are getting a big push in the Asia-Pacific region, and by China in particular, which is leaping ahead especially in sub-6GHz. It’s a complex standard, noted John Carey, the company’s director of Digital RF for the A-P region, and it’s disruptive, demanding new silicon architectures and technologies. Next year’s premium phones, he said, will include over $30 in RF components, 40mm2 of which will be based on SOI. ST has been working on RF-SOI for over two decades, and offers a range of technologies and foundry services supported by three high-volume fabs. The key benefits with RF-SOI, he explained, stem from RF FEM integration of switches, LNAs and PAs. RF-SOI technologies are here now and are successful in the markets: ST has a long-term technology roadmap and is making continued strategic investments, he concluded. Toshiba [caption id="attachment_27069" align="alignnone" width="410"] From “RF-SOI Switch LNA for Mobile Applications” (Courtesy: Toshiba SOI Consortium)[/caption] Another long-time RF-SOI user is Toshiba, although this marked their first participation in a recent Consortium event. As Group Manager Kazuyuki Uchida talked about RF techology trends, there was lots of note- and picture-taking in the audience. He pointed out that the character and size of the switch LNA modules are particularly important in the move to 5G. They’ve been leveraging their TaRFSOI(tm) process, which he said achieves the industry's lowest insertion loss, for about a decade now. The latest version, TaRF11 will be launching in Q1 of 2020. TaRF10 integrated the LNA with the switch and control circuitry in a single chip. TaRF11 will feature performance improved by about 25%. Incize [caption id="attachment_27065" align="alignnone" width="405"] From “RF Characterization” (Courtesy: Incize and SOI Consortium)[/caption] During the Incize presentation, the company’s CEO Mostafa Emam affirmed that RF-SOI is a very good business opportunity. Incize works with the complete supply chain. For foundries and wafer suppliers, they measure harmonics and output with very high precision, which is especially critical for switches. For the wafer suppliers, it’s predictive. For the foundries, it’s measuring noise for models and PDKs. While RF may be an art, second tier foundries using Incize services are now able to compete with the first tier players, he noted. He sees trap-rich RF-SOI wafers as being especially important for 5G. GlobalFoundries [caption id="attachment_27064" align="alignnone" width="599"] From “RF Reliability for SOI CMOS Si-based Power Amplifier for 5G applications” (Courtesy: GlobalFoundries SOI Consortium)[/caption] The focus of the GlobalFoundries talk was reliability in RF processes. In 5G, you need technologies that are viable for both mmWave and sub-6GHz across handsets, wifi and automotive, noted Purushothaman Srinivasan (who goes by SP and is a senior member of the company’s technical staff). In SOI, you can stack FETs (which you can’t do in bulk) for PAs, which is a big advantage in mmWave. However, delivering scalable, linear, efficient and reliable RF power technology is more challenging than digital, and requires a holistic, collaborative approach that includes the foundry, the customers and the test equipment suppliers. GF has used its RelXpert simulation tool on aging simulations and lifetime predictions for both their 22FDX and 45RFSOI processes. They have observed good RF model-to-hardware correlation, and have built Safe Operating Maps that provide guidance to RF designs. This first-in-industry RF reliability evaluation provides “highly differentiated” solutions for GF. Silvaco [caption id="attachment_27066" align="alignnone" width="606"] From “RFSOI TCAD Solution” (Courtesy: Silvaco and SOI Consortium)[/caption] Silvaco is a leading EDA provider of software tools used for process and device development and for analog/mixed-signal, power IC and memory design. Their presentation began with a review of recent updates to their TCAD simulation framework, including the TCAD design flow, Victory ProcessTM simulation for speeding up 2D/3D process simulations, and Victory DeviceTM simulation. Under Silvaco’s DTCO – Design Technology Co-Optimization – 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. Applications Engineer Sun 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 harmonic balance from the active device, device biasing and substrate, all of which can be co-optimized using Victory Process and Device. SITRI [caption id="attachment_27067" align="alignnone" width="305"] From “NB IoT FEM based on SOI” (Courtesy: SITRI SOI Consortium)[/caption] Shanghai Industrial μTechnology Research Institute – aka SITRI – is an international innovation center, focused on globally accelerating the innovation and commercialization of “More than Moore” technologies to power IoT. SITRI Director Wenwei Yang’s talk focused on their narrowband front-end module for IoT (NB IoT FEM). NB-IoT is especially meant to handle small amounts of data from remote places over long periods. There are a lot of players in this market, so taking a “good-enough” approach to performance wherein cost is primordial is key. SITRI’s low-cost NB-IoT FEM integrates everything on a single chip, including the power amplifier (PA) and integrated passive devices (IPD), so packaging costs are low. Putting it on SOI (either trap-rich or high-resistivity) gives them better isolation and simplifies integration. ~ ~ ~ Our next post will continue our coverage of the Japan Symposium. Note: 2019 marks a decade of SOI Consortium events – yes, our first one was in 2009! Because a lot of the presentations in the past were so forward-looking, many of them are still of great interest today. Currently the presentations from 2015 through to the beginning of 2019 are available freely to everyone – and are well worth perusing.

The SOI Consortium’s China 2019 event ran for two days, and it’s taken four (!) posts to cover all the presentations. In this final post we cover the afternoon RF-SOI sessions, which were dedicated to the China RF-SOI ecosystem and the RF value chain. In case you missed them, our previous posts recapped: 1. major keynotes from both the FD-SOI and RF-SOI days; 2. the FD-SOI presentations; 3. the morning sessions of the RF-SOI day; and 4. (this post) the RF-SOI day afternoon sessions. As we noted in Part 1 of our RF-SOI coverage, there were over 500 attendees for the RF-SOI day. And impressively, the room was still packed right through to the very end of the afternoon. Read on! SESSION 2: CHINA RF-SOI ECOSYSTEMSuzhou HunterSun Electronics: Super Opportunity for Integrated RFFE (“Jacky” Yujun Ding, COO)This talk had two parts. First, how is 5G changing the world, and second, what are the RFFE opportunities? He cited IHS data indicating that 5G will create tens of millions of jobs. New products include NB IoT, cellular V2X, as well as traditional PC/tablets and smart phones. But you still need to cover 2/3/4G with 5G. Major growth will happen in 2025-27. In terms of opportunities for RFFE, you've currently got 550mm2 going for $8; in 5G, you'll need 600mm2, but it will cost $16. You need RFSOI for filters and antenna switches, which are in high demand. Parts of the supply chain have no China players. Revenue for BAW is higher than SAW, but there's more SAW. He sees the industry moving heavily into integrated FEM (versus chip-on-board). He finished by itemizing different parts of the RFFE, indicating where the opportunities are (citing some data from Yole), with a special emphasis on integrated products for Chinese companies, with continued investor confidence. SmarterMicro: RF-SOI: Key Technology of Smart Connection (Yangyang Pen, Director) RF-SOI is an enabler of smart connections. However he sees GaAs as better for power, so SmarterMicro has a solution combining RF-SOI and GaAs. They've developed the world's first mMTC RFFE for high-performance upgrades on a single die and software reconfigurable. He notes that for IoT, lifetimes will be longer than 10 years, and that terminals are becoming more powerful. CanaanTek: Critical SOI CMOS Blocks in the 5G NR Sub-6GHz RF Front-End Architectures (Wayne Ni, CTO Board Chairman) CanaanTek is a fabless company working in consumer markets, with switches, tuners and LNAs in SOI-CMOS. He wants to capture 10% of the market with a focus on sub-6. The antenna/tuner is a must, and they've developed solutions for switches here. The figure of merit is RonCoff. He showed a product roadmap on SOI-CMOS. Xpeedic: Innovative EDA Solutions to Enable Differentiated RF-SOI Designs (Feng Ling, CEO)RF-SOI is growing, but there are still design challenges in process, models, filters and packaging. To design a good front end, you need better models and filters. People think passives are easy, but you need accurate models here. Xpeedic has developed design flows that include the effects of packaging early in design. Their products include IRIS, iModeler and Metis (for packaging). They've also introduced substrate modeling in partnership with CWS in France. The product is called SiPEX: it can address linearity in switch or PA designs. You need accurate substrate models to do this. Customers indicate they're seeing big improvements as well as reductions of 25% in chip area. IDP filters is another place they're working, to provide RF filters to fabless IC or module companies. No single filter technology can fit all the needs – IDP is one of them, so they have a broad portfolio of IDP filter technologies. He closed by saying that especially in China, the SOI ecosystem is really growing. SESSION 3: RF VALUE CHAINTowerJazz: Specialized RFSOI Foundry Technology to Support Rapid New Product Development (Paul Hurwitz, Director of RF Technology Development)This presentation gave a full overview of what TowerJazz offers in terms of RF-SOI foundry services with its fabs in Isreal, the US and Japan. What's new in 2019 is a diversifying of 200mm and 300mm. 200mm is best for power handling (for infrastructure/basestation antenna tuners and switch power handling, for example). 300mm is best for SW and LNA integration and higher digital densities. They've got new SOI models for the latest technology generations, and physics-based modeling of RF breakdown for accuracy. With more die being flipped, they needed new substrate modeling. For LNA and switch integration in 300mm, they invested in RF modeling. They also have an in-house MPW (multi-project wafer) program. He noted that customers in China are moving quickly in response to their customer requirements. Okmetic: Tailored Silicon Substrates for RF Applications (Atte Haapalinna, CTO)Okmetic Oy is a niche player in the substrate materials market, with specialties in sensors and MEMS, where they are the market leader. Now part of China’s NSIG group, they are expanding their manufacturing facility in Finland. In this presentation, their CTO talked about their current offerings as well as what they have under development. They do 150-200mm wafers, with a special emphasis on thick SOI. In terms of silicon substrates for RF, ultra-high resistivity is key. Their wafers are also used in IDP – integrated passive devices – for RF and acoustic filters. They are continually improving their high resistivity Magnetic Czochralski (MCz) silicon wafers, and are developing substrates for RF passives for automotive V2X. For RF beyond 6 GHz, they are looking at customized high resistivity silicon wafers for mmWave with researchers and customers. For sensors, they do SOI wafers with built-in cavities. Incize: RF SOI Ecosystem – History Challenges (Mostafa Emam, CEO)The world is exceeding expectations in terms of data usage. While the CAGR for devices is 27%, for data it’s 46%. Therefore each device needs to be faster and more power efficient. Incize recognizes RF as an art, with each piece hand crafted. But artists need to see the whole picture: at Incize, they help 17 companies – including wafer suppliers, foundries and fabless – see that big picture, especially in measurement, characterization and modeling for RF. For wafer suppliers, they do very high-power and very precise on-wafer testing to determine things like intermodulation distortion and substrate interference. For foundries, their specialty is in RF switches, for whom they do harmonics testing and thermal noise management. With those insights, Incize foundry customers have drastically increased the performance of the RF chips they’re manufacturing on trap-rich, high-resistivity SOI wafers. Meanwhile, Incize is also preparing PDKs for future potential substrate generations including GaN-on-Silicon, silicon-on-porous, and new contactless testing techniques for piezoelectric-on-insulator (POI – used in filters in 4/5G). “There’s a really big business opportunity for RF-SOI,” concluded Emam, “and room for everyone.” Cadence: SOI Technology in Intelligent and IoT/Vision/AI Systems (Jonathan Smith, Senior Director)Cadence does SOI enablement at advanced nodes. Smith shared three recent success stories. First, there’s the Musca-S1 test chip they did with Arm, Samsung and Sondrel this past spring. Second, there’s the Tensilica DSP for automotive vision on GlobalFoundries’ 22FDX, which uses 1/10th of the power of existing solutions and was demonstrated at CES. And finally there’s the i.MX line from NXP. In recent news, there’s a new version (18.1) of Virtuoso RF. Though it’s been on the market for 30 years, they’ve added advanced methodologies so that system design and analysis are on the same platform. They’ve also announced National Instruments’ analysis solver, the Clarity 3D solver for next-gen 3D solutions, the integration of multiple electromagnetic (EM) solvers, and advance SiP options. Silvaco: Xena-IP Management Infrastructure for the SOI Ecosystem (Babak Taheri, CEO)Every multi-core SoC today has as many as 200 IPs, if not more. How do you manage that? Tracking and traceability of IP is complicated but important. For IP providers, how do they track where its being used? And for IP consumers, they need to know what they’ve used and where. What’s required is an IP management system to keep track of the different functions and different concerns. Today’s tracking systems don’t talk to each other. Silvaco’s Xena IP management solution organizes all IP data, accounts, products, contracts, devices, support, compliance and reporting. For compliance in particular, they do IP “fingerprinting” and “DNA analysis”, which they’ve patented. The fingerprint is a digital representation of the IP: it’s not just software. It is secure, and can’t be reverse engineered. It’s not a tag: a tag is inserted into the IP, whereas fingerprints are extracted. DNA analysis flags discrepancies and quickly identifies where they are and which files to look in. Xena works in the cloud, enterprise systems or hybrids. The SOI ecosystem will be hearing a lot more about this. ~~ Please note that the China event presentations are all available on our website to anyone whose company or organization is a member of the SOI Consortium.

The SOI Consortium’s next annual event in Japan takes place on the 30th and 31st of October in Yokohama. Both days of the SOI Design Symposium will take place in the Yokohama Landmark Tower.

2019 will be a busy fall for the SOI Consortium and our members.First off are the SOI Consortium events in Shanghai and Tokyo, which are very popular indeed. We now have the dates locations locked in, so you’ll want to mark your calendars:Shanghai: 16 17 September 2019, FD-SOI Forum / RF-SOI Workshop. Both days will be held at the Pudong Shangri-La Hotel in Shanghai. The first day will focus on FD-SOI. The second day is all about 5G and RF-SOI. These are huge events – to get an idea of the magnitude, you can read our coverage of the 2018 event. Tokyo: 30 31 October 2019, Japan SOI Design Workshops. This year both days of workshops will take place in the Yokohama Landmark tower. The first day will be devoted to FD-SOI; the second day turns to More-Than-Moore – especially photonics and MEMS. Last year’s workshops were packed with excellent presentations and panel discussions, which we covered here. The SOI Consortium and members will also be giving talks at Semicon Europa, which is being held 13 – 15 November 2019 in Munich, Germany. The programs are currently being finalized. As soon as they’re ready, we’ll be sure to let you know so you can register and/or share the news with your colleagues and clients. But in the meantime, make sure you save the dates.Would you like to check out the presentations given at Consortium events in previous years?

S3SYou’ll also find many of our members at the IEEE/EDS S3S Conference in San Jose, CA, October 14 – 19th. S3S (formerly known as The SOI Conference) has been running in various forms for over 30 years. They always have an excellent line-up of speakers, plus it’s a great opportunity for networking with researchers from across the worldwide SOI ecosystem. BTW, while the deadline for general paper selection has already closed, papers of exceptional merit are currently being accepted for their Late News Sessions. See the 2019 Call for Papers for more information – those Late News papers need to be received by 23 August 2019 for consideration. Also, IEEE S3S Conference will once again host a full-day short course and a half day tutorial. These are very popular. The short course this year will be on SOI Design and Technology for Analog and Mixed Signal. As of this writing, the program is still being finalized, but more will be announced in the next few weeks, so check back on their website soon for updated information.Member EventsAnd finally, don’t forget to learn more about the offerings from and in support of the SOI ecosystem at our members’ events around the globe, including: GlobalFoundries – GTC | Samsung Foundry – SFF | ST – Technology Tour | Synopsys – SNUG | Cadence – CDNLive | Silvaco – SURGE | Arm – TechCon | NXP – Tech Days | Leti – Events | imec -Events |

FD-SOI for RF and mmWave communications is a hot topic. In high-data rate communications like RF and millimeter-wave devices in particular, FD-SOI delivers high-performance with numerous unique advantages, making it most likely the fastest RF-CMOS technology on the market. If you’d like to take a deep dive and learn more about it, Soitec and Incize are sponsoring a free, full-day workshop in Grenoble on April 4th, 2019. Click here for registration information. The workshop follows the day after the IEEE/EDS EuroSOI-ULIS conference there (you can read about the full conference in a previous ASN post). This technical workshop will cover the FD-SOI technology platform with a focus on its compatibility with RF mmWave communications. Attendees will hear from notable FD-SOI leaders and experts from leading industry and research institutions presenting updates on key developments and building blocks across the semiconductor value chain.
