I don't remember where I heard this before, but I'm fairly certain that Intel did, in fact, stop using that technology. Notched gates had their benefits and their sacrifices, but apparently Intel thought they could push their .18u process without it. Maybe they were able to get 100nm gate lengths using a straight wall method. After all, if AMD is able to get theirs down to 70nm, I don't see why Intel wouldn't push their .18u process a little further as well. I don't know how much AMD's yields are impacted by their aggressive measurements, but I assume going that small isn't without its compromises. At any rate, back to your question, I think you should try searching for information on this forum. I think I remember more than a few people mentioning that Intel no longer uses notched gates. Perhaps a search of posts from semiconeng can answer your question.

I know that the notch has been dropped for 0.13 micron (because of the negative tradeoffs to which you allude), but I am fairly certain that the notch is still an integral part of the 0.18 micron Intel process. I've done a quick search of the posts and my news releases and can't find anything that implies the notch has been dropped for 0.18, just 0.13... (and I was one of the people noting it when the first details of the 0.13 micron process came to light about a year ago).
