Low temperature operation of MOS devices improves performance of LSI circuits because of the increase of carrier mobility, steep subthreshold slopes, elimination of latch-up, decrease of electrical resistance and improved noise behavior.A supercomputer using CMOS circuit technology cooled at liquid-nitrogen temperatures operates at double the speed of the circuit chips as compared to room temperature operation.A further improvement of the speed in CMOS chips will be possible by optimizing the device design.
