In this paper, the circuit performances such as circuit delay, RF characteristics and SRAM static noise margin are presented. These analyses are performed by three-dimensional device simulation using Mixed-mode option. The benefit of circuit delay in scaling will be maintained by introducing new structure (SOI, multi-gate), material (silicide, metal gate) and strain effect. However, concerning with SRAM SNM, it becomes already difficult to operate even in 65nm node.
