IBM scientists find a new way to shrink transistors

New York

IN the semiconductor business, it is called the "red brick wall" - the limit of the industry's ability to shrink transistors beyond a certain size.

On Thursday, however, IBM scientists reported that they now believe they see a path around the wall. Writing in the journal Science, a team at the company's Thomas J Watson Research Center said it had found a new way to make transistors from parallel rows of carbon nanotubes.
