Accurate temperature estimation in large DMOS transistors using a semi-empirical thermal conductivity model

Abstract

A method for improving the temperature estimation accuracy in large DMOS transistors based on a semi-empirical fitting model for the Si thermal conductivity is presented. The model is used in the analytical solution of the 3D transient heat equation. The performances of the method are further improved by taking into account the power metallisation using a… (More)
