Abstract

To investigate the role of self-heating effects on the electrical characteristics of nano-scale devices, we implemented a two-dimensional Monte Carlo device simulator that includes the self-consistent solution of the energy balance equations for both acoustic and optical phonons. The acoustic and optical phonon temperatures are fed back into the electron transport solver through temperature dependent scattering tables. The electro-thermal device simulator was used in the study of different generations of nano-scale fully-depleted (FD) Silicon On Insulator (SOI) devices that are either already in production or will be fabricated in the next 5-10 years. We find less degradation due to self-heating in very short channel device structures due to increasing role of non-stationary velocity overshoot effects which are less sensitive to the local temperature.
