Robert, Re: "I would be interested in some explanation however as to why Intel believes that SOI becomes less of a benefit as geometries shrink below 0.13 (this was a statement they made about 3-6 months ago)."

Actually, Intel made that statement last year, and it appears they are sticking to it. I imagine that at the very least, Intel ran some SPICE models on their transistors to see what the benefits could be.

The thing with SOI is that there are pros and there are cons. The pros have been talked about constantly, but the fact that SOI is more expensive, it produces lower yields, and there isn't a methodology of running it on 300mm wafers as of yet, are rarely mentioned.

I'm guessing that Intel has other methods besides SOI of lowering current leakage. As Ali showed, it can be a considerable portion of the overall power produced, so it's obviously a problem that needs a solution quickly. At the very least, it's something that Intel will have to improve before their .09u process.
