Results show that, this technology suppresses effectivily short-channel effects. The sheet resistance of active region decreases by four times. The sheet resistance of polysilicon gate region decreases by one order of magnitute. Using this technology, the speed of the 3 μm NMOS 12-bits multiplier increases by two times relative to conventional one.展开更多
