Abstract:
1. A semiconductor structure comprising: a III-nitride substrate having a first side and a second side opposing the first side, wherein the III-nitride substrate is characterized by a first conductivity type and a first dopant concentration; a III-nitride epitaxial layer of the first conductivity type coupled to the first surface of the III-nitride substrate; a first metallic structure electrically coupled to the second surface of the III-nitride substrate; an AlGaN epitaxial layer having a first side coupled to the III-nitride epitaxial layer of the first conductivity type; and a III-nitride epitaxial structure of a second conductivity type coupled to the AlGaN epitaxial layer on a second side of the AlGaN epitaxial layer, the second side being opposite the first side, wherein the III-nitride epitaxial structure comprises at least one edge termination structure.
