Abstract:
Fabrication of a heterostructure, such as a group III nitride heterostructure, for use in an optoelectronic device is described. The heterostructure can be epitaxially grown on a sacrificial layer, which is located on a substrate structure. The sacrificial layer can be at least partially decomposed using a laser. The substrate structure can be completely removed from the heterostructure or remain attached thereto. One or more additional solutions for detaching the substrate structure from the heterostructure can be utilized. The heterostructure can undergo additional processing to form the optoelectronic device.

Claim (Index 18):
A heterostructure comprising:\n a substrate structure including:\n a substrate having a patterned surface; and \n a set of group III nitride buffer layers directly adjacent to the patterned surface of the substrate, wherein the set of group III nitride buffer layers includes \n a set of vacancies where no semiconductor material is present; a set of group III nitride device layers located adjacent to the substrate structure; and a sacrificial layer located between the substrate structure and the set of group III nitride device layers, wherein the sacrificial layer includes a sublayer directly adjacent to the set of group III nitride buffer layers, wherein the sublayer includes a set of regions formed of a semiconductor material and a set of vacancies located laterally adjacent to the set of regions.
