Power semiconductor module arrangement comprising heat-conducting layer and heat sink and method for producing the same

Abstract

A power semiconductor module arrangement includes a power semiconductor module, wherein the power semiconductor module includes a substrate for carrying at least one semiconductor body, and a heat-conducting layer arranged on a lower surface of the power semiconductor module, wherein the lower surface of the power semiconductor module is a surface that is configured to be mounted to a heat sink, and wherein the heat-conducting layer consists of a metallic and non-eutectic material that is solid at temperatures below a first threshold temperature, that is viscous at temperatures above the first threshold temperature and below a second threshold temperature, and that is fluid at temperatures above the second threshold temperature.
