Abstract

We describe a heterojunction based half bridge apparatus formed within a single active area comprising a first heterojunction device and a second heterojunction device, each heterojunction device comprising a drain and a source, each drain comprising a drain contact and each source comprising a source contact; wherein the drain contact of the first heterojunction device and the source contact of the second heterojunction device comprise a common contact. The half bridge apparatus according to the present disclosure may be advantageously more compact and more reliable than existing heterojunction based half bridges.
