IWCE 2015 presentation. This paper discusses a multi-scale device modeling scheme for analyzing self-heating effects in nanoscale silicon devices. A 2D/3D particle-based device simulator is self-consistently coupled to an energy balance solver for the acoustic and optical phonon bath. This simulator is used to analyze the hot-spot temperature and location in various SOI devices, dual gate structures and nanowire transistors. This device simulator has been coupled to a SILVACO simulation tool which solves for heat transport in interconnects at the circuit level. The proposed multi- scale simulation scheme allows for analysis of thermal effects in an integrated circuit. Simulation results obtained with this simulator are in agreement with experimental measurements from IMEC using specialized heater-sensor test structures in common-source and common-drain configurations.
