Who is excited about tri-gate? It's a new transistor that Intel says it's going to use for the 45nm process.

Basically:


"Further advances at Intel, like trigate transistors will essentially place transistor interconnects on a 3D grid instead of a 2D one - allowing for much higher densities without revamping lithography or gate size."

- September 9, 2004

Since originally announced last year, Intel researchers have successfully shrunk the size of the trigate transistor (measured by the gate length) from 60 to 30nm.

Transistors with a smaller gate switch on and off faster, ultimately enabling faster microprocessors.

"Our latest research indicates that the scalability, performance and excellent manufacturability of our trigate transistor makes it a strong contender for production as early as 2007 on our 45nm process technology", said Sunlin Chou, Senior Vice President and General Manager of Intel's Technology and Manufacturing Group.

"The results place nonplanar 3D transistor structures among the promising nanotechnology innovations that we will use to extend silicon scaling and Moore's Law well into the future".

The trigate transistor design also addresses the growing current leakage problem that the industry faces as CMOS devices are made ever smaller.

Due to its unique structure, the trigate transistor's leakage is far less than that of a planar transistor of the same size.

That is the basis of the INQ's posting a few months back that Intel had solved the leakage problem. They are also transitioning to new metals.

From what everyone reports, the 45nm process is going to be awsome, so i'm kinda looking foward to it and its cool-running CPUs.
 
Intel's "trigate" is just another name for a FinFET. Not that its not a promising development...but the Intel press release reads like they invented the whole idea of nonplanar transistors.

how is it not that promising? It outperforms SOI (benchmarked a few years ago) and buts leakage by a lot as well as allows them to create higher density chips, so i'm not understanding your logic.
 
I used to get excited about reading things like this but then I gave up. I just read and move on. They seem to just disappear once a little blog has been written on it. For example; people have been saying for years how solid-state secondary storage will become mainstream, can't think of other examples now but you get the idea hopefully :)

But hopefully this will be used and all the better for us :)

Samsung is going to ship the first hybrid hard drives in just a few months time...solid state secondary storage mated to a normal drive.

Sounds cool, when is AMD going to adopt this :cool:

As of now, this is an Intel development. I hear AMD was developing something similar, but it would only have two sides. But, as of now, they are sticking to SOI.

Sorry, my bad. Read it wrong...again
 
I looked at the press release before I read the rest of the thread, and I was like "whoop de doo, a finfet". Yes, it's a finfet. Neat stuff, and not an intel-only development. Given, Intel is buying all the student researchers who do anything in the finfet arena, as is smart business to do.

Not sure what you mean...SOI and nonplanar transistors aren't mutually exclusive. They don't have to abandon SOI to go with FinFETS.
