Patent ID: 7875910

Claim:
A monolithic electronic device, comprising: a common nitride epitaxial layer; a first type of nitride device including a first epitaxial nitride structure on the common nitride epitaxial layer; a second type of nitride device, different from the first type of nitride device, including a second epitaxial nitride structure that is different from the first epitaxial nitride structure on the common nitride epitaxial layer; a first plurality of electrical contacts on the first epitaxial nitride structure, the first plurality of contacts defining a first electronic device of the first type of nitride device; and a second plurality of electrical contacts on the second epitaxial nitride structure, the second plurality of contacts defining a second electronic device of the second type of electronic device; wherein the common epitaxial layer comprises a layer of semi-insulating Al x Ga 1-x N (0<x<1).
