Join us! In partnership with our members, the SOI Consortium is co-organizing and participating in two key SOI events coming up in China over the next few weeks. On May 18th, we’ve put together an SOI Forum at the World Semiconductor Congress (WCS) in Nanjing. And on May 23rd & 24th, we’ve teamed up with our members SIMIT, Sitri and Leti for another in our series of SOI Academies, including an FD-SOI Training Day. (The last one this past winter was a terrific success – read about that here if you missed our coverage at the time.)
At WCS, the SOI Forum (sub-forum #8) is part of the afternoon Innovation Summit. We’ll cover the broader SOI ecosystem, including both RF-SOI and FD-SOI – from wafers to design through manufacturing. Presentations will be given by members of the SOI Consortium team, and by leaders from our membership, including Simgui, NXP, Incize, ST, IBM, Cadence and Xpeedic. Click here or scan the QR code for the full program and registration information.
Also at WCS, SOI Consortium member VeriSilicon will be participating in a morning session on AI and IoT Wireless Communications (sub-forum #4). They’ll be giving a presentation on their low-power Bluetooth design platform for GlobalFoundries 22FDX, and their CEO Wayne Dai will be moderating a round-table discussion. You can get more information on that (in Chinese only, tho) here, or follow VeriSilicon on WeChat.
The SOI Academy in Shanghai is an opportunity for experienced designers to gain solid expertise in FD-SOI. The event begins in the afternoon of May 23rd with a series of informative plenary talks by members of the SOI Consortium team, and by experts from our members Leti, Soitec, VeriSilicon, GlobalFoundries and NXP. The FD-SOI Training starts the next morning, on May 24th.. This is a hands-on event lead by top experts from Leti. The morning is devoted to digital design in FD-SOI, and the afternoon to RF design (including for 5G) in FD-SOI. Attendees will get a comprehensive understanding of design techniques for low-power chips leveraging the multiple benefits and flexibility of FD-SOI technology. Get more information here, or from the WeChat QR code.
We’ve got a busy schedule! To keep up to date with where we and our members will be promoting the SOI ecosystem, be sure to check our Events page regularly.
Key takeaway #2: If you need a Goldilocks process node – where you’ll get just the right balance between active power, unit cost and investment – look to FD-SOI. And, btw, the IP landscape has improved dramatically. Those were just some of the great points made by Huibert Verhoeven (shown above), GM/SVP of Synaptics’ IoT Division in his talk at the recent SOI Symposium in Silicon Valley.
BTW, if you missed part 1 of our coverage —Silicon Valley SOI Symposium a Huge Success. Key Takeaways (Part 1) Here. – you’ll want to be sure to read it, too. Almost all of the presentations are now posted on our website – click here to access them.
In this post here, we’ll cover presentations by Synaptics, GlobalFoundries, STMicroelectronics, Anokiwave and Dolphin Integration. It was a really full, day, so be sure to stay turned for Part 3 of our coverage to follow shortly: it will highlight the remaining presentations and panel discussions.
Synaptics’ Verhoeven’s presentation Revolutionizing User Experience Through Secure Neural Network Acceleration at the Edge was about Smart Home and using SOI. Synaptics is a human interface (HMI) company that’s been doing neural networks since 1986. They’ve always been on the leading edge, from their first shipment of PC touchpads to becoming a dominant force in all things HMI today: they now ship over a billion units annually.
They currently have SOI products shipping with dedicated neural networks for voice, he said. European [privacy] regulations have played a part in driving their use of SOI, as have challenges regarding power and heat. Things are getting smarter at the edge. For example, not only do users want their coffee machine to offer the usual morning espresso, Synaptics says that the next step is for your coffee machine to recognize you’re looking extra tired and ask if you might want a double?!
For them Smart Home and multi-modal applications are the primary area of interest, as well as some automotive. Although their biggest customers have resources, others need guidance. Voice is a critical component, but now you also need video and display.
Why SOI? Their HMI vision requires low power, significant computation and dedicated neural network hardware, explained Verhoeven, so FD-SOI with RF meets their needs. “22nm SOI is a Goldilocks IoT Process Node,” he proclaimed. It gets the combination of active power, unit cost and investment just right. What’s more, he said, “The IP landscape has improved dramatically. Our choice of SOI was not an accident.” Be on the lookout for more products leveraging FD-SOI over the next six months, he concluded.
At this point on SOI, they’ve got 1 TOPS products with dedicated NPU for speakers, soundbars, Wi-Fi mesh, appliances, STBs and smart displays. These products have voice and sensor real-time (RT) AI. Next up is >4 TOPS on SOI with dedicated NPU, targeting STBs and smart displays with voice, video, imaging and RT AI.
“Our clients are at the forefront of changing the world,” declared Mark Granger, VP of the Automotive Product Line at GlobalFoundries. His presentation, Capturing High Growth Market Opportunities with SOI, detailed how mobility, automotive and IoT are the growth markets for SOI. So not unsurprisingly, GF’s 22nm FD-SOI technology, 22FDX, is seeing particular traction in mobile, edge, wearables and automotive.
They’ve got twice as many tape-outs this year as they did a year ago, he noted. GF’s SOI portfolio includes 22FDX®, 45RFSOI and 8SW/7SW RF SOI for 5G/mobility; 22FDX for automotive (fully qualified for automotive Grade 2, with Grade 1 on the way); and 22FDX, 130RFSOI and 8SW/7SW RF SOI for IoT.
GF has announced a stream of good news recently:
You might have heard about the Dolphin Integration news, as we covered it recently here at ASN (if not, be sure to read it here). Dolphin’s IP and methodology solutions address energy efficiency challenges. Automated transistor body biasing adjustment can achieve up to 7x energy efficiency with power supply as low as 0.4V on 22FDX designs. At the Silicon Valley event, Dolphin Integration CEO Philippe Berger provided additional information in his talk, FD-SOI IP Platform for Energy-Efficient IoT SoC.
In another GF-related talk, Nitin Jain, the CTO of longtime GF RF-SOI customer Anokiwave presented Unleashing the mmWave Phase Array Using SOI for 5G & Satcom. Anokiwave is a fabless semi IC company (you’ll find a good technical discussion of mmWave phase array written by their Chief Architect here). They do active antennas (aka phased array), something the military’s done for a long time, but now Anokiwave is bringing it to new markets and applications including radar, satcom and 5G. What they’ve been able to do is planarize the active antennas. They use GF’s 45RFSOI process technology for phased array systems because of the cost, performance, scalability and system enhancements it enables. 45RFSOI, he explained, is ideal for beam-forming FEMs (including the switches, LNAs and PAs). The move to 5G/mmWave is going to require a lot of antennas, so these Anokiwave ICs are headed to high volumes, concluded Jain.
As Roger Forchhammer, Director of Business Development at STMicroelectronics pointed out in his presentation, Automotive FD-SOI Microcontrollers with Embedded PCM, ST pioneered FD-SOI (and that was almost a decade ago, btw). Then in February 2019, they announced a world first: they’d begun sampling 28nm FD-SOI microcontrollers (MCUs) with embedded non-volatile memory (eNVM) based on embedded Phase-Change Memory (ePCM) to 10 alpha customers. These MCUs target powertrain systems, advanced and secure gateways, safety/ADAS applications, and vehicle electrification.
(In case you want technical details, the breakthrough ePCM eNVM was first presented at IEDM in December 2018 – you can get the presentation that accompanied the paper, Truly Innovative 28nm FDSOI Technology for Automotive Microcontroller Applications embedding 16MB Phase Change Memory, from the ST website.)
In his Silicon Valley presentation, Forchhammer said they’re now doing Stellar, a whole family of automotive products on FD-SOI. To do it, they’d taken an existing device and moved it to 28nm FD-SOI with ePCM, which they manufacture at their fab in Crolles, France. A major advantage for automotive he cites is that in software updates it’s bit-level programmable. “ST is fully behind FD-SOI,” he concluded, adding that we’re see more automotive as well as IoT products coming soon.
Well folks, that’s all for this post. We’ll finish up our coverage of the SOI Consortium’s 2019 Silicon Valley Symposium in the next ASN post (there was so much to cover!). So please stay tuned.
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. Topics will include circuit design, device fundamentals, simulation and characterization of RF devices, test, CMOS technology and substrate technologies enabling FD-SOI. In addition, the workshop will include an overview about how FD-SOI technology is benefiting current and future end user applications.
Here’s the agenda:
Following the immense success of last year‘s FD-SOI training day in Silicon Valley, the SOI Consortium has another one planned for the end of April this year. If you want to start learning how to leverage FD-SOI in your chip designs, this is a great place to start. Click here for information on how to sign up.
ST Fellow Dr. Andreia Cathelin has put together another great line-up. World renowned professors and experts from industry will deliver a series of four training sections of 1.5 hours each, focused on energy efficient and low-power, low-voltage design techniques for analog, RF, high-speed, mmW and mixed-signal design.
You’ll learn about design techniques that take full advantage of the unique features of FD-SOI, including body biasing capabilities that further enhance the excellent analog/RF performances of these devices.
Each section of this training day will take you through concrete design examples that illustrate new implementation techniques enabled by FD-SOI technologies at the 28nm and 22nm nodes – and beyond.
The design examples will cover basic building blocks through SoC implementations. A global Q&A session will close the day.
Here’s a little more info on how the day will unfold. Click on the slides to see them in full screen.
FDSOI-specific design techniques for analog, RF and mmW applications – Andreia Cathelin, Fellow, STMicroelectronics
Andreia Cathelin is ST’s key design scientist for all advanced CMOS technologies, and is arguably the world’s leading expert on leveraging FD-SOI in high-performance, low-power RF/AMS SoCs. Her course will first present a very short overview of the major analog and RF technology features of 28nm FDSOI technology. Then the focus moves to the benefits of FD-SOI technology for analog/RF and millimeter-wave circuits. She’ll give design examples such as analog low-pass filters, inverter-based analog amplifiers and 30GHz and 60GHz Power Amplifiers, as well as mmW oscillators. There will be particular focus on the advantages of body biasing and special design techniques offering state-of-the-art performance.
Circuit Design Techniques in 22nm FD-SOI for 5G 28GHz Applications – Frank Zhang, Principal Member of Technical Staff, GlobalFoundries
Frank Zhang has designed chips using GF’s 22nm FD-SOI (22FDX) process for WLAN, 5G cellular and automotive radar applications. His course will focus on how to take advantages of FD-SOI’s high-frequency performance at relatively low-current density to design high performance RF/mmWave circuits. Examples circuits include a 28GHz LNA, a 28GHz PA and an RF switch for 5G applications. The FD-SOI advantages such as low capacitance, high breakdown voltage and high-output impedance will be exploited in these design examples. This course will also discuss how to extend these techniques to applications at higher frequencies and/or higher current densities that are subject to extreme temperatures and EM requirements.
Energy-Efficient Design in FDSOI – Bora Nikolic, Professor, UC Berkeley
Borivoje (“Bora”) Nikolić is known as one of the world’s top experts in body-biasing for digital logic (he and his team have designed more than ten chips in ST’s 28nm FD-SOI.) If you missed it, his team’s RISC-V chip was cited as one of Dr. Cathelin’s “Outstanding 28nm FD-SOI Chips Taped Out Through CMP” – read more about that here. His talk at the training day will present options for energy-efficient mixed-signal and digital design in FD-SOI technologies. He’ll explain how to generate body bias and use it to improve efficiency, with examples in RF and baseband building blocks, temperature sensors, data converters and voltage regulators. The techniques will be presented in the context of UC Berkeley’s latest RISC-V-based SoC, designed to operate in a very wide voltage range using 28nm FD-SOI.
mm-Wave and Fiber-Optics Design in FD-SOI CMOS Technologies – Sorin Voinigescu, Professor, University of Toronto
Sorin Voinigescu is a world renowned expert on millimeter-wave and 100+Gb/s ICs and atomic-scale semiconductor device technologies. His lecture will cover the main features of FD-SOI CMOS technology and how to efficiently use its unique features and suitable circuit topologies for mm-wave and broadband SoCs. He’ll begin with an overview of the impact of the back-gate bias and temperature on the measured I-V, transconductance, fT, and fMAX characteristics. Then he’ll compare the maximum available gain, MAG, of FDSOI MOSFETs with those of planar bulk CMOS and SiGe BiCMOS transistors through measurements up to 325 GHz. Next, he’ll provide biasing, sizing and step-by-step design examples for VCO, doubler, switches, PA, large swing optical modulator drivers and quasi-CML circuit topologies and layouts that make efficient use of the back-gate bias to overcome the limitations associated with the low breakdown voltage of 20nm and 12nm FD-SOI CMOS technologies.
With over 100 attendees filling every chair in the auditorium, last year’s training day was sold out. Although it was in Silicon Valley, people actually flew in from all over the world to be there. During the Q&A at the end, most everyone prefaced their questions by saying, “Thank you. I really learned a lot today.”
2018 will be no different – except that it’s sure to sell out even faster. Please note, though, that this is not a free event, so only the attendees will get copies of the slide decks.

This is the second part of ASN coverage of Day 2 of the recent SOI Workshop in Tokyo, which was dedicated to the “Convergence of IoT, Automotive through Connectivity”. Many of the presentations are now posted and freely available – click here to see the full list.
Peter Rabbeni, GlobalFoundries’ Sr. Director of 5G BizDev and Product Line Marketing focused on mmWave and why/how 5G. In his talk, Delivering on the Promise of 5G: Semiconductor Solutions for the Next Wave of Data, he pointed out that there’s not one solution for all use cases – but there is an SOI solution for all the opportunities.
You need mmWave for latency, simultaneous connectivity, energy-efficiency and mobility, he explained. mmWave addresses the trade-off between distance and data rates. In a phase array, the beam is steered, but because of atmospheric absorption, you have to do multiple beams at high frequencies.
RF-SOI technology is already found in virtually every smartphone in the world. Now, he sees two main benefits in RF-SOI (a partially depleted technology that uses “trap-rich” substrates, btw) in the move to 5G and mmWave. One is device stacking, which you can do in SOI to overcome the Johnson Limit (a tradeoff between breakdown voltage and frequency). The other comes from the benefits inherent in the substrate: high-resistivity, high-Q and isolation. It means you can have smaller arrays for each element, and fewer chips per array. That’s key: you need those smaller arrays for handsets and customer premises equipment.
Different designers are taking different approaches to RF, he notes. There are those doing FEM-centric designs, which integrate from the antenna back toward the transceiver. And then there are those that are doing integration-centric designs, which target integration from the transceiver/BB toward the antenna. The first approach is being driven by those customers with unique IP and presence in the front-end module space. The other is being driven by folks with IP and presence in the SOC space. Both will exist in some form, he contends. 45RFSOI is well aligned with the first case and focused primarily with FEM leadership performance and integration. 22FDX, on the other hand, is very well suited for transceiver/baseband ADC/DAC integration and can integrate the FEM functionality as well. Pathfinding on the FEM integration component is on-going for 22FDX.
SOI is “…the perfect solution to our needs”, said Steven Yeung, Design Manager with MIPS/Imagination Technologies in his talk, MIPS Leading Heterogenous Compute in Automotive & IP. The cost of failure is increasing he noted, citing the ISO standard 26262 for functional safety in road vehicles, and SOI “helps a lot”.
As noted in the presentation title, research powerhouse Leti sees that the Future of the Automotive Industry is Paved With SOI. Vincent Roger of Leti’s Corporate Business Development made convincing arguments as to why FD-SOI is the right solution for automotive:
you need advanced digital circuitry for all computational tasks in the automotive environment
the 3-generation node gap between automotive and consumer is closing
FD-SOI is more power efficient than planar bulk (both at 28 and 22nm) or FinFET (16nm)
it’s simpler in terms of design and IP portability than FinFET
it’s a proven solution, with better reliability and lower design costs
it addresses all performance levels and communications
it simplifies integration of control electronics for distributed sensors
Leti is actively working on getting RF capabilities in FD-SOI adopted more quickly. For example, they are developing RF models for their UTSOI-2 modeling suite for FDSOI, including back bias effects. And they’re also developing innovative basic design blocks that prove the technology validity and add new functionality.
He also sees an even bigger role for RF-SOI, the technology of choice for RF Front End Modules for connected vehicles and 5G applications. With Soitec, they’re working to keep improving existing substrates and introduce new concepts.
SOI wafer suppliers (Soitec, SEH and Simgui) are expanding capacity, said Soitec EVP Thomas Pilisczcuk. His talk, The Role of Substrates in Accelerating Mass Adoption of SOI Technologies, reviewed the various SOI substrates and partners across FD-SOI, RF-SOI, photonics, power, image sensors and more.
Soitec is launching a program called FIRST (for First Integration Ramp of SOI Toolbox) to help customers reach competitive yields fast. They are also help customers facilitate SOI integration into design and manufacturing.
There are still more talks that are now posted on the SOI Consortium website. IHS/Markit made a very interesting high-level presentation on LIDARs & Sensor Fusion ECUs Advancing ADAS Architectures Toward Automated Driving, which called for chipmakers to integrate more features. Nokia Future X Network for 5G & IoT looked at infrastructure (they use their own chipsets). ST looked at smart cities in Sensor-to-Cloud Connectivity for IoT.
Equipment makers are also eager participants in the FD-SOI ecosystem. Screen’s presentation was entitled Full Participation Within the SOI Consortium. The Applied Materials talk, Enabling SOI and IoT: An Equipment and Materials Engineering Perspective, covered how they’re working with their customers and their customers’ customers to understand the trends and enable the device roadmap.
Mark your calendars: the next workshop sponsored by the SOI Consortium will be in Shanghai this September 26th and 27th (one day is all about FD-SOI, the other about RF-SOI). You can now register or ask for an invitation: see Events on the SOI Consortium website. Last year’s Shanghai event was really dynamic and absolutely packed, so you’ll want to make sure you register early. (But if you can’t make it, you can of course read about later it in ASN!)
GlobalFoundries has announced availability of its 45nm RF-SOI technology (read the press release here). Dubbed 45RFSOI, the company says it’s the first 300mm RF solution for next-gen mmWave beamforming applications in future 5G base stations and smart phones.
The technology supports mmWave spectrum operation from 24GHz to 100GHz band, 5x more than 4G operating frequencies.
Skyworks’ CTO Peter Gammel says that the 45RFSOI process, “…is enabling Skyworks to create RF solutions that will revolutionize emerging 5G markets and further advance the deployment of highly integrated RF front-ends for evolving mmWave applications.”
The news was quickly picked up by publications across the industry, with EETimes noting that RFSOI has been a big GF success story.
Production will be at the company’s East Fishkill fab. The PDKs are available now.
The 45RFSOI news follows hard on the heels of GF’s announcement a few days prior that the company is teaming up to build a fab offering 22nm FD-SOI in western China, that it’s expanding its Dresden FD-SOI capability by 40 percent, and that it’s adding new RF-SOI capabilities to its fab in Singapore.
GlobalFoundries is a member of the SOI Industry Consortium.
