Abstract:
1. A method comprising: growing a plurality of III-nitride semiconductor structures on a substrate, wherein: each semiconductor structure comprises a light emitting region disposed between an n-type region and a p-type region, wherein the light emitting region comprises a first quantum well, a second quantum well, and a barrier disposed between the first and second quantum wells: the substrate comprises a host, a plurality of islands of III-nitride material separated by trenches, wherein the trenches extend through an entire thickness of III-nitride material that forms the semiconductor structures, and a bonding layer disposed between the host and the plurality of islands of III-nitride material, the bonding layer comprising one of glass, borophosphorosilicate glass, SiO x , SiO 2 , SiN X , Si 3 N 4 , HfO 2 , Mo, Ti, TiN, and dielectric; and the light emitting region of each semiconductor structure has an a-lattice constant greater than 3.19 angstroms; forming a conductive material that electrically connects two of the III-nitride semiconductor structures; and after growing the plurality of III-nitride semiconductor structures on the substrate, removing the host.
