Large-scale, computer-aided thermal design of power GaAs integrated devices and circuits

Abstract

A three-dimensional large-scale thermal simulation tool is applied to the design of power III-V devices and integrated circuits (ICs). After a short description of the modelling approach, which allows for non-linear multilayered and thinned substrates, via holes, and heat conduction through surface metallizations, simulation examples are discussed concerning GEC-Marconi power MESFETs with improved heat sinking and power ICs.
