There’s been a significant uptick in patents related to fully-depleted SOI, according to a new report by KnowMade (click here to get the report brochure). The report looks at both FD-SOI and SOI-FinFETs (both of which are fully depleted technologies). More than 740 patent families have been published to date, of which planar FD-SOI accounts for 340 families. Following a rush of activity about 10 years ago there was a dip, but activity over the last couple of years has once again been very strong.
The report provides a comprehensive overview, essential patent data for fully depleted SOI, plus a searchable database with links. It identifies more than 30 patent holders of FD-SOI related intellectual property, providing in-depth analysis of key technology segments and key players. “The major proponents of the FD-SOI technology have strong IP arms, but other unexpected players known as not supporting FDSOI [including TSMC and Intel] are also present,” notes the report.
AMD has made two new 32nm SOI-based product announcements:
The 38th annual SOI Conference is coming up in just a few weeks. Sponsored by IEEE Electron Devices Society, this is the only dedicated SOI conference covering the full technology chain from materials to devices, circuits and system applications.
Chaired this year by Gosia Jurczak (manager of the Memories Program at imec), this excellent conference is well worth attending. It’s where the giants of the SOI-related research community meet the leading edge of industry. But there are also excellent courses for those new to the technology. And it’s all in an atmosphere that’s at once high-powered yet intimate and collegial, out of the media spotlight.
This year it will be held 1-4 October at the Meritage Resort and Spa, a Napa Valley luxury hotel and resort, set against rolling hills with its own private vineyards. Finding the right spot for this conference is key. One of the things that people really like about it is that in addition to the excellent speakers and presentations, the locations are conducive to informal discussions and networking across multiple fields. This year’s spot looks like the perfect setting, with easy access to Silicon Valley.
The Conference includes a three-day Technical Program, a Short Course, a Fundamentals Class, and an evening Panel Discussion. Here’s a look at what’s on tap for this year.
(To register at the discounted rate, be sure to send in your registration by September 17th. You can get the pdf of the full program & registration information from the website.)
ARM’s SOI guru Jean-Luc Pelloie chaired this year’s Technical Program committee, which selected 33 papers for the technical sessions. There will also be 18 invited talks given by world renowned experts in process, SOI device and circuits design and architectures and SOI-specific applications like MEMS, high temperature and rad-hard.
Here’s a rundown of the sessions:
Short course: Design Enablement for Planar FD & FinFET/Multi-gates (chaired by UCL & Leti) The conference kicks off on Monday with six sessions by experts in technological trends, the physics of fully depleted devices, technology design kits as well as digital, analog and RF designs specific for FD-SOI.
The fundamentals course: FinFET physics (chaired by Intel): on Wednesday afternoon, three hour-long sessions will give comprehensive insights into the physics and processes related to multi-gate FETs.
Panel: Is FinFET the only option at 14nm? (chaired by Soitec) Following the always-popular Wednesday evening cookout, the panel discussion is a lively favorite event. This year’s invited distinguished experts will share their views on the industry’s FinFET roadmap.
All in all, it’s a great event. If you go, why not share your impressions on Twitter with #SOIconf12, @followASN and @IEEEorg? And of course ASN will follow-up with summaries of the top papers in our PaperLinks section. See you there?
The new 32nm SOI Bulldozer-based AMD Opteron™ Processors will power the National Science Foundation’s Blue Waters project. Per the TOP500 Supercomputers list, more than two million AMD Opteron cores power many of the world’s fastest supercomputers across 14 countries.
With performance, efficiency, and power optimization as top priorities, AMD’s innovative Bulldozer architecture is built on 32nm SOI.
As of the Fall of 2011, AMD is shipping both client and server CPUs based on the new Bulldozer architecture. The first of the new APUs (CPU + GPU) incorporating Bulldozer modules will start shipping in 2012.
All of AMD’s innovative new Bulldozer architectures are built on 32nm SOI technology fabbed by GlobalFoundries.
Bulldozer is the code name for AMD’s next-generation CPU core, which targets the two key “heavy lifting” markets:
As indicated on the AMD roadmap, all of the company’s CPUs for the “server” market – chips in the Opteron family – are based on the 32nm SOI Bulldozer architecture.
The roadmap for “client” products also shows key chip families for desktop processors and high-performance notebooks based on the 32nm SOI Bulldozer architecture.
Interlagos is the codename for AMD’s 12- or 16-core 32nm SOI server processors based on the new “Bulldozer” processor core. It carries the AMD Opteron™ 6200 and 6100 Series processor brands and is supported by the AMD Opteron™ 6000 Series (“Maranello”) platform.
Interlagos includes the world’s first 16-core x86 processors. The first Interlagos shipments began in August 2011 to large custom supercomputer installations: 25,000 to Oak Ridge labs and 38,000 to Los Alamos, for example.
The latest AMD FX series marks the first retail availability of Bulldozer-based processors. Available in 8-, 6- and 4-core configurations, these CPUs targets extreme multi-display gaming, mega-tasking and HD content creation for PC and digital enthusiasts.
The new FX includes the first-ever eight-core desktop processor, which took the Guinness World Record for the “Highest Frequency of a Computer Processor,” hitting a top speed of 8.429 GHz.
AMD has dubbed the company’s new Fusion APUs the era of “Personal Supercomputing”. The A-Series APUs, codenamed Llano, that started shipping in mid-2011 are based on 32nm SOI, but their CPUs are based on the previous generation of the x86 CPU architecture, and as such are not yet Bulldozer.
However, the next generation in the A-Series APUs, codenamed Trinity and scheduled for release in 2012, will also be based on 32nm SOI with next-generation Bulldozer CPU cores.
The Bulldozer architecture is based on “modules” of two cores each. AMD explains that this means two simultaneous threads can be executed more efficiently than two threads running on a single integer core.
For each two-core module, there is a shared 2MB L2 cache. The shared L3 cache varies from 8MB to 16MB, depending on the processor.
The Bulldozer design is new from the ground-up. It required co-development of power efficiency, timing, and functionality¹. The team reduced leakage power by 95% when both cores are idle by module-level VSS (rather than VDD) power gating, first used in the 32nm Llano CPU. SOI enables this to be done without extra processing steps².
The L1 caches use an 8T storage cell. The design team said that the change from a 6T cell in 45nm to 8T in 32nm improved the low-voltage margin and read timing and reduced power³.
This game-changing architecture on SOI promises an exciting new era of high performance and low power in systems ranging from sleek but powerful notebooks to the fastest supercomputers on the planet.

Overclocked to 8.429 GHz , the AMDFX (Bulldozer) CPU has entered the Guinness World Book of Records for “Highest Frequency of a Computer Processor”. On 32nm SOI from GlobalFoundries, the 8-core FX will launch in Q4 2011, targeting gamers.
Calling it “a monumental moment for the industry”, AMD has begun revenue shipments of its new 32nm-SOI “Interlagos” processors, the first CPUs based on the “Bulldozer” architecture. Fabbed by GlobalFoundries, “Interlagos” is the codename for AMD’s 12- or 16-core 32nm SOI server processor based on the new “Bulldozer” processor core. It carries the AMD Opteron™ 6200 Series processor brand and is supported by the AMD Opteron™ 6000 Series (“Maranello”) platform.
The International Solid-State Circuits Conference – better known as ISSCC – is of course where the big guns show us their big advances at the chip level. At the most recent conference, held a few weeks ago in San Francisco, advances that leveraged SOI were once again at the forefront.
As always, performance gains generate plenty of buzz. But the SOI papers were also notable for work reducing power consumption, extending scalability and overcoming threshold voltage variation.
IBM presented the world’s highest frequency microprocessor to date, clocking in at 5.2 GHz. On 45nm SOI, it’s the first commercial processor ever to break through the 5GHz speed barrier, and is the centerpiece of Big Blue’s new zEnterprise 196 system.
In another paper, IBM presented the first embedded high-k/metal-gate (HK/MG) SRAM on 32nm SOI enabling operation at down to 0.7V.
AMD presented its Bulldozer 2-core modules, which are on 32nm SOI with HK/MG. Clocking in at 3.5GHz, we’ll see them beginning in desktop and server Fusion chips this year.
In a quieter but clearly significant paper, ST and Leti compared 65nm low power (LP) partially depleted (PD) SOI with standard 65nm LP CMOS bulk. They found that PD-SOI, when combined with a low resistivity produced with forward body bias of the power switch, can reduce leakage current by 52.4% vs. bulk and increase the frequency by 20% at 1.2V, while decreasing power by 30% at 360MHz.
