1.Abstract Based on the software PISCES for simulation of semiconductor device, software SE-PISCES for simulation of semiconductor device at low temperature is develpoed bymodifying model equations and adding paremeter models for low temperature. The steadystate property, transient property and AC small signal analysis of diode at low temperature are simulated and are compared with the simulation resluts at 300K.
