FinFETs may have a similar limit. In 2006, a team at the Korea Advanced Institute of Science and Technology used electron-beam lithography to build 3-nm FinFETs. But crafting a single device isn't quite the same as packing millions together to make a microprocessor; when transistors are that close to each other, parasitic capacitances and resistances will draw current away from each switch. Some projections suggest that when FinFETs are scaled down to 7 nm or so, they will perform no better than planar devices.

So it looks like AMD will be transitioning over to SOI and Intel will be using FinFET. Fine by me, either way I thought this article was fairly interesting to read, a good bit of education going on in it for me hopefully others enjoy!

::edit:: I just realized how that looked. It's not flaming either Intel or AMD, I just can't seem them both going with the same designs. Intel has much more capital to work with than AMD I believe, so for AMD to go with FinFET they would have to rely on Intel's work as well as shell out a ton of money. I don't think they're in a particularly strong position in the market overall, which leads me to believe they would lean toward SOI instead of FinFET.

so whats next?
the current transister path wont last forever, or much longer really...so
will it be "quantum" or "organic"....what?

good article man, thanks

Yes, Moore's law won't continue forever. Calculating with atoms is the likely replacement.

after that it'll be calculating with quarks

I don't mean to sound dumb but I thought AMD already used SOI in their process. Wouldn't that mean they are sticking with it and not going to it?

That's right. AMD abandoning SOI would be news.

Organic as in Carbon, Nitrogen, Oxygen, Hydrogen, etc?

We'll see 3D Transistors, New Architectures and new Materials until we've reached the absolute limit of a metallic processor that is a Finite State Machine.

From there you will see software improvements until something else comes along and revolutionizes the industry.
