Self-heating and current degradation in 25 nm FD SOI devices with (100) and (110) crystallographic orientation

Abstract

In this paper we present simulation results obtained with our electro-thermal particle-based device simulator for 25 nm fully depleted silicon-on-insulator devices with (100) and (110) crystallographic orientations. We also investigate the importance of the proper choice of the thermal conductivity model (which is particularly important for thin silicon films) in properly predicting the average maximum temperature and the maximum temperature in the hot spot which are important parameters regarding device reliability.
