Claim:
1. A semiconductor device having a first side and a second side opposite the first side, wherein the semiconductor device is formed from an epitaxial substrate, the semiconductor device comprising: a stack of semiconductor materials comprising a heterojunction region formed from the epitaxial substrate, wherein at least one of the semiconductor materials defines a bulk region adjacent the heterojunction region; a carrier comprising a substrate at the first side of the semiconductor device, wherein the carrier is configured to carry the stack of semiconductor materials such that the bulk region is between the substrate and the heterojunction region; conductive regions adjacent the heterojunction region and configured to provide an electrical current through the heterojunction region; a dielectric material between the heterojunction region and the substrate of the carrier: a first electrode extending through the bulk region and coupled to one of the conductive regions; a second electrode extending through the bulk region and coupled to another one of the conductive regions; a third electrode extending through the bulk region, the dielectric material and the heteroiunction region; and wherein the epitaxial substrate is removed from the second side of the semiconductor device, and wherein the semiconductor device further comprises a structure at the second side of the semiconductor device from which the epitaxial substrate was removed.
