Abstract

A microwave semiconductor device, for example, Gunn effect devices, avalanche diodes and varactors, having a mesa-like semiconductor body which is provided on both sides with respective grown metal contact layers. The upper side of the semiconductor body is provided with a beam lead which projects from the upper side. The metal contact layer of lower side of the semiconductor body is a grown heat sink or, as in the varactors, a beam lead.
