IBM Making Moves Toward 22nm Chips

It might not be as well publicized as Micheal Phelps' race to 14 gold medals, but there's another kind of race going on in the chip industry, and that's to see who will be the first to reach 22nm. But it might not be Intel leading the way, and instead it looks as though IBM may be emerging as the front runner.

Unlike the path to 45nm and 32nm, getting to 22nm presents some significant challenges for chip makers, one of which includes getting the circuits "printed" in a process called photolithography. As IBM engineer Subu Iyer notes, "Once the wavelength of light becomes comparable to the size of the thing you're trying to print, things break down. The challenge is to use a light wavelength of 192 nanometers because 'extreme ultraviolet' radiation is still impractical."

Iyer went on to say that in terms of physics, getting to 22nm is a tall order requiring a tremendous amount of computation. To help with that, IBM has developed what it's calling the Computational Scaling (CS) initiative, which includes support from several of IBM's partners. If nothing else, this collaboration puts added heat on Intel, who downplayed IBM's foray into 22nm earlier this summer.

Might IBM beat Intel to the punch? Hit the jump and make your prediction.
