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:
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? If you hover your cursor over the Events tab at the top of our home page, you’ll get a drop-down menu of events for the last five years (we’re working on adding more – we’ve been doing these events for over a decade!). Click through to any past event and you’ll land on a page where you can download most of the presentations that were given there. Of if you’re looking for past presentations given by any particular company, use the search engine at the bottom of any page on our website.
You’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.
And 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:
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:
Suddenly they’re everywhere: opportunities to learn more about FD-SOI and RF-SOI. Over the next couple of months you can find them in China, Europe and Silicon Valley. Some are organized by the SOI Consortium, others by foundries and partners.
Here’s a quick listing with links for more info on how to register for upcoming China events.

Now in its 5th year, this conference has grown very quickly: last year it was in a ballrooom with standing room only (note that RF-SOI chips are now found in pretty much every smart phone on the planet). The focus this year is on IoT, mobile, 5G connectivity, and mmW. Keynotes are from TowerJazz, Sony and China Mobile. Presentations from RDA, SMIC, Simgui, Will-Micro, GF, Soitec, Silvaco and Screen.
BTW, for events organized by the SOI Consortium, many of the presentations are available on the website (from Tokyo this summer, for example, and Silicon Valley last spring – and going on back through 2015). Scroll down through Events to Past Events to find them.
The FD-SOI ecosystem is strong. This was made clear at the recent Tokyo SOI Workshop, organized by the SOI Consortium. The event was spread out over two days, and most of the presentations are now posted (click here to access them). To cover the full scope of the workshop will take (at least) a couple ASN posts. So let’s start with Day 1, which was billed as the “FD-SOI Ecosystem” day.
It kicked off with a full-house for an afternoon session in the Yokohama Landmark Tower hosted by Silvaco, with presentations from some of the key players in the FD-SOI Ecosystem.
David Sutton, CEO of EDA provider Silvaco opened the session with his talk, TCAD, EDA & IP to Support FD-SOI. Silvaco has deep FD-SOI roots, having supported Lapis Semi (formerly Oki) in its first forays into the technology – and that was back in 2002! The company is on a growth run this year, having acquired four companies, including IPextreme.
FD-SOI, he said, has been shown to be cost-effective. The capacity is in place, and it’s getting design wins. Silvaco’s full suite of EDA and custom CAD tools for FD-SOI cover the complete design flow from TCAD to sign-off. Their IP is very strong, he said, especially in automotive (including CAN IP), and their partnerships with key players like IBM and NXP are long running. In fact, Silvaco commercializes IP from NXP and others.
We got some great insights from Gregg Bartlett, GlobalFoundries’ SVP of the CMOS Business Unit, in his presentation FDX (FDSOI) Goes Mainstream – Roadmap for Product Competitiveness (it’s posted – click here to download it). “It is primetime for FD-SOI,” he said, and since one technology does not fit all, they’re redefining the mainstream. GF’s first FD-SOI offering, 22FDX, was qualified in March, and 12FDX will be taping out in the second half of 2018. They’ve currently got over 80 active engagements.
FD-SOI will be strong in China, he said. GF and the Chengdu municipality recently announced they are investing more than $100 million to build a world-class FD-SOI ecosystem including multiple design centers in Chengdu and university programs across China. This will lower the barriers to entry and increase IP availability even further, he said. They’re looking to put 500 design engineers in place. Customer tape-outs of 22FDX will begin at the new fab there in 2H2018, with volume production expected to start in 2019.
He went on to drill down on FDX applications, focusing on four main areas:
mobility: application processors that need high performance, RF integration and significant power reduction
IoT: this was the target when FDX was first conceived, and it continues to be a point of significant investment by the company
RF and mmWave: for BLE (Bluetooth Low Energy), WiFi, ZigBee and integrated PA’s (aka power amplifiers – where they’re seeing some impressive numbers, he said)
automotive: Grade 2 is done, and Grade 1 is underway (these are industry ratings related to reliability at the high-temperatures you get under the hood and in hotspots in the passenger compartment).
Citing a slide of customer testimonials, he concluded that the ecosystem is really starting to work, adding that they’ve got the right technology for the right applications, and it’s the right path for them to be on.
Invecas has been working on 22FDX since 2015 through a strategic partnership with GF. They’ve optimized IP and offer ASIC services, explained Bhaskar Kolla, the company’s Sr. Director of BizDev & Customer Engineering. His presentation, Invecas IP Portfolio in 22FDX is posted – click here to get it. It’s full of detail (standard cells, memories, analog & IO, and interface), so you’ll really want to check it out. The IPs are silicon proven and validated; the results are available, he said.
The foundation IPs are sponsored by GF, so they’re free to customers and cover a broad array of calibrations. They include forward and reverse body biasing (FBB and RBB) and body bias generator IP. Customers are really taking advantage of this, he said, citing as an example one that’s going for 2.5GHz by leveraging FBB.
Custom IP for analog & IO is a place they’re seeing a lot of interest, he continued, and on which they’re doing more and more work with clients. And their Interface IP is in a lot of silicon, especially for customers that are area sensitive. In fact, they’ve developed their own Interface IP demo platform in-house, from build through test and compliance checks.
In moving to FD-SOI, customers are seeing significant PPA improvements, he said. In one of the customer use cases for a high-level IoT product he cited, the customer requirements were easily achieved: cutting leakage in half, dynamic power consumption by roughly a third and area by 20%.
There’s so much technical detail on performance boosters in Laurent Grenouillet’s presentation, FD-SOI: a Low Power, High Performance Technology Scalable Down to 10nm, you really just have to look at it yourself – click here to get it. A CMOS & Memory Integration Expert at Leti, he did a quick review of 28-22-14nm, then took a deep dive into the myriad of performance boosting options for 10nm, including impressive benchmarking regarding the effectiveness of mobility boosters on FD-SOI vs. FinFET.
Here are the boosters he detailed for 28-22-14nm:
Interestingly he noted that with each node, the thickness of the insulating BOX layer of the SOI wafer scales down, and as it does, back bias efficiency improves even more.
Here’s what he then covered for 10nm (and detailed with data packed in the 20 slides that followed):
FD-SOI is the sweet spot when you need lower power, lower cost, more sensing (analog), more comm (RF), more flexibility and more energy efficiency, he concluded – and he provided powerful data to back that up.
I-fuseTM: the best OTP of Choice for FD-SOI and sub-14nm nodes was the topic of a talk by Attopsemi Technology’s Chairman, Shine Chung (you can get the ppt here). The company recently joined GF’s FDXcelerator partner program. OTP stands for one-time programmable memory, and I-fuse is different from other OTP technologies (notably NVM and e-fuses), he explained, in that it’s a non-breaking fuse with ultra-high reliability even in high-temp conditions. It’s been qualified by companies worldwide and is in volume production.
He’s a big fan of FD-SOI because it offers the best RF integration, small form factor, ULP and low cost. Want to make a cellphone as small as a watch? Then you need FD-SOI, he quipped with a tip of the hat to a Dick Tracy image. The fact that FD-SOI has a lower junction breakdown than bulk makes I-fuse the best choice for it, he said. You just program a gate as a fuse.
During breaks (on both days!), everybody was talking about the terrific Product Design Methodology presentation by Christophe Tretz, the SOI Consortium’s design guru (and longtime IBM guy). In fact, Christophe has agreed to write it up for ASN in the weeks to come, so don’t miss that. You’ll want to look at the whole presentation — click here to get it. In the meantime, here are some highlights.
He suggests designers consider an incremental approach in which FD-SOI benefits accrue. “No, you don’t have to know everything about the technology to use it,” he began (especially addressing those in smaller design teams and houses). “The ecosystem is there. Everything you need to use it is there.”
He used a number of cases to explain.
Case 1: a simple, digital SOC – you get significant power savings just by reusing existing library blocks and doing minor recompile.
Case 2: RF/mixed-signal – turnaround time is very fast (Analog Bits, for example cut leakage by 5x in a port that took just three months). FD-SOI gives analog designers a great new thing to play with for big power savings – and they learn fast.
Case 3 (= Cases 1 + 2): “complex” SOC with RF blocks – rework the RF blocks, but reuse library elements for the digital part without a lot of design effort. You get significant power savings very easily.
Case 4: a more complex SOC – in this case, you optimize or customize a few blocks in the first design pass, but then optimize/customize more blocks in subsequent design passes. It just keeps getting better and better.
Case X: a fully optimized SOC. This takes more time, but you can do parts in parallel and get dramatic results – especially if you use body biasing.
He then looked at the state of the ecosystem:
three fabs are ready
we have the tools (Synopsys, Cadence, Silvaco)
the libraries are there and ready to use
“You don’t have to learn everything to get your product out the door,” he concluded. “You don’t have to do it all at once: you can do it incrementally. Within a few months, you’ll have a nice product, and as you do new products every six months, each time you can re-use, but also tune for more improvements.”
In short: just do it!
So that’s a recap of Day 1. Next post (or posts?) I’ll recap Day 2. Stay tuned!
