7nm, 5nm and 3nm Logic, current and projected processes

7nm, 5nm and 3nm Logic, current and projected processes
by Scotten Jones on 06-25-2018 at 7:00 am

There has been a lot of new information available about the leading-edge logic processes lately. Papers from IEDM in December 2017, VLSIT this month, the TSMC and Samsung Foundry forums, etc. have all filled in a lot of information. In this article I will summarize what is currently known.… Read More


Semicon West – The FDSOI Ecosystem

Semicon West – The FDSOI Ecosystem
by Scotten Jones on 07-21-2017 at 12:00 pm

At Semicon West last week I attended presentations by Soitec and CEA Leti, and had breakfast with CEA Leti CEO Marie Semeria, key members of the Fully Depleted Silicon On Insulator (FDSOI) ecosystem. I have also seen some comments in the SemiWiki forum lately that make me believe there is some confusion on the roles of different companies… Read More


LETI Days 2017: FD-SOI, Sensors and Power to Sustain Auto and IoT

LETI Days 2017: FD-SOI, Sensors and Power to Sustain Auto and IoT
by Eric Esteve on 07-07-2017 at 7:00 am

I have attended last week to the LETI Days in Grenoble, lasting two days to mark the 50[SUP]th[/SUP] anniversary of the CEA subsidiary. Attending to the LETI Days is always a rich experience: LETI is a research center counting about 3000 research engineers, but LETI is also a start-up nursery. The presentations are ranging from Read More


Always-On IoT – FDSOI’s Always Better? What About Wafers? (Questions from Shanghai)

Always-On IoT – FDSOI’s Always Better? What About Wafers? (Questions from Shanghai)
by Adele Hars on 11-03-2016 at 7:00 am

Mahesh Tirupattur, EVP at low-power SERDES pioneer Analog Bits lead off the panel discussion at the recent FD-SOI Forum in Shanghai with the assertion that for anything “always on” in IoT, FD-SOI’s always better. They had a great experience porting their SERDES IP to 28nm FD-SOI (which they detailed last spring – see the ppt hereRead More


New Cortex-M7 Chip to Help Power Sophisticated IoT Solutions

New Cortex-M7 Chip to Help Power Sophisticated IoT Solutions
by Tom Simon on 11-01-2016 at 4:00 pm

IoT architects face a dilemma in partitioning the compute power of their systems between the cloud and the edge. The cloud offers large storage and heavy duty compute power, making it an attractive place to perform the computation needed for IoT tasks. However, moving large amounts of data from the edge to the cloud servers, can … Read More


The Status and Future of FDSOI

The Status and Future of FDSOI
by Scotten Jones on 09-26-2016 at 12:00 pm

I recently took a look at the current status and future direction of FinFET based logic processes in my Leading Edge Logic Landscape blog. I thought it would be interesting to take a similar look at FDSOI and to compare and contrast the two processes. My Leading Edge Logic Landscape blog is available here.… Read More


SRAM Optimization for 14nm and 28nm FDSOI

SRAM Optimization for 14nm and 28nm FDSOI
by Daniel Payne on 05-16-2016 at 4:00 pm

I’ve done SRAM and DRAM design before as a circuit designer from 1978-1986, but in 2016 there are so many more challenges to using 28nm and 14nm on FDSOI technology. One way to keep abreast of SRAM design is to read conference papers, so I just finished a paper from authors at STMicroelectronics and MunEDA presented at the IEEE… Read More


According with ST, SiC Power Devices will Accelerate Automotive Electrification

According with ST, SiC Power Devices will Accelerate Automotive Electrification
by Eric Esteve on 05-16-2016 at 10:39 am

Silicon Carbide (SiC) is a very interesting material. If you find in nature the mineral moissanite, it will be only minute quantities in certain types of meteorite. The moissanite physical properties are very similar to these of diamond, in term of density and abrasive power. In the semiconductor industry, SiC is characterized… Read More


No reason for FD-SOI Roadmap to follow Moore’s law!

No reason for FD-SOI Roadmap to follow Moore’s law!
by Eric Esteve on 04-26-2016 at 4:00 pm

We in Semiwiki are writing about FD-SOI since 2012, describing all the benefits offered by the technology in term of power consumption, price per performance compared with FinFET, etc. Let me assess again that I am fully convinced that FD-SOI is a very smart and efficient way to escape from the Moore’s law paradox: the transistor… Read More


In the Valley & thinking about FD-SOI for your next chip design? Epic (and free) symposium 13 April

In the Valley & thinking about FD-SOI for your next chip design? Epic (and free) symposium 13 April
by Adele Hars on 04-02-2016 at 7:00 am

If you’re in the chip biz in Silicon Valley, check out the SOI Consortium FD-SOI Symposium on April 13th in San Jose. They’ve been running these things since 2009, and I have to say that this one is the most comprehensive to date. Headliners include Cisco, Sony, NXP, SigmaDesigns, ARM, Ciena plus the big FD-SOI foundries,… Read More
