Paper Abstract

Temperature dependent low-field mobility models in the commercial device simulation program are studied to check their effects on the drain characteristics. The results show that low-field mobility has not effect on threshold voltage, subthreshold swing, and the saturation voltage, but it is very important in determining the drain saturation current, transconductance, and the channel conductance of the CMOS devices under low temperature operation. Better understanding of the carrier mobility and the usage of it in the simulation program can help us in designing high performance circuits and process development for the low temperature applications.
