Not PC segment, not necessarily Application Processor for Mobile, despite the power efficiency advantage versus a bulk technology. After several weeks filled by very animated and controversial discussion about FD-SOI cost, thanks to Semiwiki bloggers and readers, it seems interesting to elevate the debate and try to figure… Read More
FD-SOI: 20nm Performance at 28nm Cost
There has been a lot of controversy about whether FD-SOI is or is not cheaper to manufacture than FinFET. Since right now FinFET is a 16nm process (22nm for Intel) and FD-SOI is, for now, a 28nm process it is not entirely clear how useful a comparison this is. Scotten Jones has very detailed process cost modeling software (that is what… Read More
Keywords: FD-SOI, Cost, FinFET
How to synthesize a pretty good article Is SOI Really Less Expensive, and even more important the impressive amount of comments (56) generated? Let’s start with the initial article. Pretty good, but slightly biased, when you carefully dissect it, like I did in one of the comments (you can find it in-extenso at the end of this post).… Read More
STM FD-SOI Manufacturing Double Source: Samsung
Let’s start with apologies: when guessing that SMIC would be the 2[SUP]nd[/SUP] source foundry for ST-Microelectronics 28nm FD-SOI, I was wrong. To be honest, if I had made the assumption that Samsung was this double source, I would have generated dozen of comments, calling me “crazy blogger”…for the best. Announcing Samsung… Read More
FD-SOI : SMIC or…Who else?
In fact, as of today, nobody can refer to an official statement made by any STM executive about name of the foundry able to process FD-SOI wafers in 28nm. We just know that the agreement is about to (or has been) signed… But we may speculate, and try to use our rational thinking. For example, the Semiwiki readers had the opportunity to… Read More
FD-SOI Not Just For France Any More, China Signs On?
The COO of ST Microelectronics, Jean-Marc Chery announced that they have signed a new foundry agreement for FD-SOI. What he actually said doesn’t reveal who the foundry in question is:“We have just signed a strategic agreement with a top-tier foundry for 28nm FD-SOI technology. This agreement expands the ecosystem, assures… Read More
FD-SOI Better Than FinFET?
As I said earlier in the month, I was going to be talking about FD-SOI at the Electronic Design Process Symposium (EDPS) in Monterey. I am not especially an expert on FD-SOI but I know enough to be dangerous and given that we were already talking about FinFET and 3D/2.5D chips, it fitted in nicely.
The 10,000 foot view is that FD-SOI has… Read More
Handel Jones on FD-SOI vs FinFET
Handel Jones has a new white-paper out titled Why Migration to FD-SOI is a Better Approach Than Bulk CMOS and FinFETs at 20nm and 14/16nm for Price-Sensitive Markets. Handel has done an in-depth analysis of the wafer and die costs of the various approaches, bulk planar (what we have been doing up to now), FD-SOI and FinFET. The analysis… Read More
The Technology to Continue Moore’s Law…
Can we agree about the fact that the Moore’s law is discontinuing after 28nm technology node? This does not mean that the development of new Silicon technology, like 14nm or beyond, or/and new Transistor architecture like FinFET will not happen. There will be a market demand for chips developed on such advanced technologies: mobile… Read More
If you still think that FDSOI is for low performance IC only…
…then you should read about this benchmark result showing how digital power varies with process corners, for high-speed data networking chip, not exactly the type of IC targeting mid-performance mobile application. Before discussing the benchmark results, we need to have some background about this kind of ASIC chip. Such a … Read More
