The 14-nanometer process node in semiconductor manufacturing will offer a number of technical challenges that cannot be addressed by simply scaling down from previous nodes, according to IBM's James Warnock. "The 14nm node poses a host of challenges for designers, because the solutions to problems with scaling have been postponed by previous generations," he said in a recently presented paper. "The end is nearish, and will eventually be determined by economic issues, but at 14nm there is no way to get more performance by scaling alone."
