For the second consecutive year the SOI Consortium will have a stand at the Networking Reception during the Samsung Foundry Forum (SFF). This important Silicon Valley event will be held on May 14, 2019 at the Santa Clara Marriott. We hope you’ll stop by to learn more about the SOI Consortium and the FD-SOI ecosystem.
There’s been a steady stream of news about Samsung’s FD-SOI offerings and support, including their highly successful 28FDS and coming very soon: 18FDS. (If you need to catch up, click here to read more.) As in the previous 3 years, Samsung will be making major announcements on their technology roadmap and application solutions. SFF is a unique opportunity to network with Korean and US based executives from Samsung Foundry as well as customers and ecosystem partners.
SOI Consortium members ARM, Synopsys, Cadence, Analog Bits, VeriSilicon and Xpeedic will also have stands, and NXP will be on the customer panel.
Seats are limited, so go to http://www.samsungfoundryforum.com/2019/ to register now.
That FD-SOI can be a key to achieving near-threshold voltage design was an important point made during a #55 DAC expert panel. Entitled How Close to Threshold-Voltage Design Can We Go Without Getting our Fingers Burnt? the session was organized by Jan Willis of Calibre Consulting. Turnout was excellent. Btw, Jan (herself an EDA expert) was one of the original advisors in the formation of the SOI Consortium, and while this DAC panel was not meant to be about FD-SOI, it turned out be a focal point.
Near-threshold voltage design* is an especially hot topic for IoT and edge-computing designers, for whom balancing performance, reliability and extremely low power is generally challenge #1. For them, the ability to get chips working at very low voltages translates into battery life savings.
The original goal of the panel was “…to explore how far below nominal voltage we can design, in what applications it makes sense and in what ways it will cost us.” The description in the #55 DAC program noted that “Energy consumption is the driving design parameter for many systems that must meet ‘always-on’ market requirements and in IoT in general. For decades, the semiconductor industry has attempted to leverage the essential principle that lowering voltage is the quickest, biggest way to reduce energy for a SoC. Some today contend sub-threshold voltage design is viable while others argue for near-threshold voltage design as the minimum.”
(Update 2 August 2018: a complete video of this panel is now available on YouTube — click here to view it.)
The panelists included:
Brian Fuller of Arm served as moderator.
Following the panel Jan published the following excellent recap on LinkedIn. She graciously agreed for it to be reprinted here in ASN, for which we thank her. So without further ado, read on!

Brian Fuller, Arm, skillfully guided a group of experts through the challenges of near-threshold design to conclude that the adoption is going to start gathering pace in a panel session at the 55th DAC in San Francisco on Monday, June 25.
Scott Hanson, CTO of Ambiq Micro, led off by saying the list of what’s not challenging is a much shorter list but that by taking an adaptive approach, they have been successful. It’s required innovating throughout the design process including test where Scott said they had create their own “secret sauce” to make it work. Later on in the panel, Scott described designers in near-threshold as “picojoule fanatics” to overcome the limitations in design tools which are geared towards achieving performance goals.
Lauri Koskinen, CTO of Minima Processor, agreed that adaptivity is key. Minima says it has to be done in situ in the design to make it robust for manufacturing while useful across more than one design. Later in the panel, Lauri indicated that FD-SOI is like having another knob available for optimizing energy in the Minima approach to near-threshold design.
Mahbub Rashed, head of Design and Technology Co-Optimization at GlobalFoundries, highlighted the need for more collaboration between EDA, IP, and foundries to support near-threshold design but noted a lot of progress has been made on FD-SOI processes. Mahbub cited models down to 0.4V for FD-SOI processes are available now and GlobalFoundries is able to guarantee yield.
Paul Wells, CEO of sureCore, validated that sureCore has bench marked their memories on GlobalFoundries FD-SOI with success. He reflected that FD-SOI has rapidly established itself as cost effective for a number of emerging markets. The panel all agreed that achieving quality on the memory at near-threshold voltage was much tougher than for digital IP. [Editor’s note: sureCore‘s CTO wrote an excellent summary of their SRAM IP for FD-SOI in ASN back in 2016 – you can still read it here.]
Paul went on to summarize at the end of the panel that near-threshold voltage is the way of the future and that it’s gathering pace. Mahbub called upon the EDA community to step up to improve the tools for low energy design. Lauri and Scott both summarized that there were drivers emerging that will grow the addressable market for near-threshold voltage design. Lauri pointed to growth coming from the applications that require edge computing which he thinks will require near-threshold voltage design. Scott concluded the panel by pointing out that there’s been a tremendous increase in performance of near-threshold voltage designs which will increase the addressable available market in the future.

* As explained by Rich Collins of Synopsys in the TechDesign Forum: “Operating at near-threshold or sub-threshold voltages reduces static and dynamic power consumption, at the cost of design complexity. […] A transistor’s threshold voltage (Vth) is the voltage at which the transistor turns on. Most transistor circuits use a supply voltage substantially greater than the threshold voltage, so that the point at which the transistors turn on is not affected by supply variations or noise. […] In sub-threshold operation, the supply voltage is well below the Vth of the transistors. In this region, the transistors are partially On, but are never fully turned. Near-threshold operation happens between the sub-threshold region and the transistor threshold voltage Vth, or around 400 – 700mV for today’s processes.
RF-SOI is in every smart phone out there, and with 5G, there are lots more applications on the horizon. If you’d like to learn more about designing in RF-SOI, there’s a great short course coming up the day before and in conjunction with the EuroSOI-ULIS Conference in Granada, Spain.
The title of this short course is RFSOI: from basics to practical use of wireless technology. Program and registration details can be found here. The course runs for the full day on Sunday, 18 March 2018.
The talks, which are being given by a stellar line-up of experts, include:
BTW, this year marks the 4th joint EUROSOI – ULIS Conference. The EuroSOI Conference, which has been ongoing for decades, is well paired with the ULtimate Integration on Silicon Conference. The joint conference provides an interactive forum for scientists and engineers working in the field of SOI technology and advanced nanoscale devices. One of the key objectives is to promote collaboration and partnership between different players from academia, research and industry. As such, it covers technical topics, industry trends and updates from pertinent European programs.
EuroSOI-ULIS will take place 19–21 March 2018 at the University of Granada in Spain. For information on the program and how to register, see the website. Following the conference, the papers will be available at the IEEE Xplore® digital library, and the best papers will be published in a special issue of Solid-State Electronics.
The FD-SOI and RF-SOI events in Shanghai and Nanjing were absolute success stories. Over the course of five days, hundreds of executives and design engineers packed halls for talks by the leaders of the top ecosystem players, and for tutorials given by the world-renowned design experts.
These annual events have been ongoing in China now for a few years now. Citing the tremendous growth of SOI, Dr. Xi Wang, DG of SIMIT and head of the Chinese Academy of Science in Shanghai said in his keynote, “We’ve come a long way.” Five years ago, he recalled, very few people in China even knew what SOI was. Today the central government has recognized its value, and the ecosystem is riding a wave of growth and strength. A national industrial IC group has been approved for investment, and design/IP are ready. The industry has reached a consensus, he said, that FD-SOI is cost-effective and complementary to Finfet, while RF-SOI has reached an almost 100% adoption rate in front-end switches for mobile phones.
Many of the presentations are now publicly available on the Events page of the SOI Consortium website. Here are the links:
Over the next few weeks, I’ll cover the highlights of each of these events. Their success clearly represents a tremendous vote of confidence for the SOI ecosystem in China and worldwide.
“The success of these SOI events is a testament to China’s recognition of the great opportunity of SOI-based chip technologies. FD-SOI decreases power consumption and enables deep co-integration of digital, analog, RF, and mm-wave. RF-SOI enables 4G and 5G connectivity with even richer integrated functionalities. It allows the fusion of the RF switch, LNA, and PA, for supporting both traditional sub-6GHz but also mm-wave frequency ranges. SOI technologies also offer a means for China – already the world’s largest chip consumer – to leap to the forefront of chip design and manufacturing,” noted Giorgio Cesana, Executive Co-Director of the SOI Consortium.
The events were followed by top tech news outlets in China. Links follow below (the pieces are in Chinese; or you can open them in Google Translate or Chrome to read them in the language of your choice). Tip: in these pieces you’ll find lots of great pics of key slides, including some that have not been shared on the Consortium website.
FD-SOI coverage included pieces in top pubs such as EETimes China, EEFocus, EDN China (plus a focus piece) and Laoyaoba to name a few. Leading bloggers also posted excellent overviews as well as pieces about specific presentations, including those by Samsung, GlobalFoundries and Handel Jones.
The 2017 Joint International EuroSOI Workshop and International Conference on Ultimate Integration on Silicon (ULIS) will be held April 3-5 in Athens, Greece. Although EuroSOI has been ongoing for many years, this marks the third year it joins forces with the ULIS conference. Sponsored by the IEEE and EDS, the goal is to create an interactive forum for scientists and engineers working in the field of SOI technology and advanced nanoscale devices. As such, a key objective is to promote collaboration and partnership between different academia, research and industry players in the field. For more information, visit the EuroSOI-ULIS ’17 website.
FD-SOI makes sense for China. That was the key message SOI wafer leader Soitec made in a press conference on FD-SOI for a select group of journalists just before Semicon China this spring. News then quickly spread, and resulted in over 150 FD-SOI articles in the top China technology and business press.
Soitec also put together a super FD-SOI resource page, with lots of information in Chinese (you can see it here).
Soitec execs Thomas Piliszczuk, SVP of Marketing & Biz Dev and Christophe Maleville, SVP of the Digital Electronics BU joined forces with the CEO of the Chinese wafer company Simgui and the VP of the National Silicon Industry Group (NSIG). They made the case that FinFETs, bulk and FD-SOI will co-exist, FD-SOI is an excellent technology for China on two fronts:
It was a powerful set of messages and clearly resonated throughout the press. Here’s a quick look (with a little help from Google Translate…) at what some of the top publications had to say.
The ChinaByte article was one of many that reported on the key points that the Soitec folks made at their press conference, leading with the headline that FD-SOI can help the China innovation blueprint. Other points included:
With a daily page views of over 1.7 million, CCINET is an influential site. The headline they ran was about how Soitec has promoted the ecosystem of FD-SOI and shares its innovate engineered substrates in China (link here). The thrust was that FD-SOI represents an opportunity for China. It covered the basics of FD-SOI, Soitec’s role as the leading global engineered substrate expert and partnerships in China with Simgui and Sitri, and FD-SOI’s strong ecosystem.
In a long and detailed piece, EETimes-China documented Soitec’s decade-long history in China, explained the special role of Soitec’s Smart CutTM technology in manufacturing the ultra-thin wafers for FD-SOI, then covered the scope of the ecosystem and the value propositions. There was also a follow-up piece by International Editor Junko Yoshida in the global edition of EETimes (see here).
Many publications focused on how Soitec and FD-SOI supports China’s innovation plan. They include: Power System Design; ECCN; Electronic Products China; 21ic; Electronic Engineering & Product World; EC.HC360; Microwave Journal; and China Electronic Market
China Electronic News noted how FD-SOI supports “Made in China 2025”. The headline of the China Business Journal article (which got a lot of WeChat attention) positioned FD-SOI as a new choice for the semiconductor industry, and a chance for China become an industry leader. EEWorld cited Simgui’s and NSIG’s affirmation that FD-SOI adoption is moving fast and will have a bright future in China. EEFocus looked at how FD-SOI compares with FinFETs (very well!), and cites Soitec’s Maleville as saying FD-SOI represents a 6 million wafer/year opportunity in China by 2020.
SST/China called FD-SOI the best choice for mobile and IoT. Of course we can’t cover all the other articles here, but with the Soitec press conference having generated over 150 pieces in the China tech and biz press, that message is now clearly out there.
The SOI Consortium has lined up an excellent, comprehensive FD-SOI Symposium on April 13th in San Jose. They’ll be highlighting the tremendous progress of the FD-SOI ecosystem. Headliners include Cisco, Sony, NXP, SigmaDesigns, ARM, Ciena plus the big FD-SOI foundries, EDA companies, design partners, chipmakers and analysts. There is a special session dedicated to RF and analog design innovation on FD-SOI with STMicroelectronics, Stanford and others. In short, we’re going to get a chance to see the FD-SOI ecosystem in action.

EDI CON China 2016, taking place April 19-21 in Beijing at the China National Convention Center (CNCC) will feature a keynote talk by GlobalFoundries‘ Peter Rabbeni, Sr. Director, RF BU Business Development & Product Marketing. The talk, entitled, “RF SOI: Revolutionizing Radio Design Today and Driving Innovation for Tomorrow”, will kick off the newly added RF-SOI Technology Track. The SOI Track will also feature talks and workshops from Peregrine Semiconductor, TowerJazz, Simgui, AnalogSmith and Shanghai Jiao Tong University. The talks will cover substrate engineering, design enablement, CMOS power amplifier design techniques and highly integrated control devices.
Mr. Rabbeni’s keynote talk will cover how there has been dramatic growth in RF SOI over the last several years in its continued march in driving performance improvement, cost reduction and architecture innovation between the transceiver and the antenna in mobile radios. No other radio technology in recent memory has had the impact that RF SOI has had in this respect. With standards becoming increasingly more challenging and the pending introduction of 5G, RF SOI is expected to continue to play an important role in the development of innovative architectures. His presentation will explore where we have been, why and where we may be headed with this technology. Substrate engineering and SOI device technology is reviewed in detail in Microwave Journal’s October 2015 cover story at http://www.microwavejournal.com/articles/25255.
