Patent ID: 8786053

Claim:
A gallium and nitrogen containing device comprising: a handle substrate member comprising a first surface region and a second surface region, wherein the second surface region is opposite the first surface region; an adhesion layer overlying the second surface region; a gallium and nitrogen containing material overlying the adhesion layer, wherein the gallium and nitrogen containing material comprises at least one a core region extending through a thickness of the gallium and nitrogen containing material; an interface region overlying the gallium and nitrogen containing material; at least one n-type epitaxial growth region overlying the interface region; at least one core structure extending from the at least one core region and through a thickness of the at least one n-type epitaxial growth region; an active region overlying the at least one n-type epitaxial growth region; a p-type region overlying the active region; and at least one p-contact region overlying the p-type region.
