Slatterz writes "Intel may be touting 45nm CPUs, but IBM says it can go much further with a strategy to produce future chips using a 22nm fabrication process. The company is adopting a technique called 'computational scaling' in order to manufacture circuits small enough to deliver more powerful and energy-efficient devices. Intel plans to introduce 32nm chips in 2009, but chipmakers have hit a problem in that current lithographic methods are not adequate for designs as small as 22nm owing to fundamental physical limitations. IBM claims to have solved this problem." Unfortunately the phrase "computational scaling" doesn't actually convey any information about how they've solved it.
