Abstract:
1. A device comprising: a III-nitride semiconductor structure including an active region disposed between an n-type region and a p-type region, the semiconductor structure having a top side and a bottom side; a photonic crystal structure disposed on a top side of the semiconductor structure; a first contact electrically connected to the n-type region and a second contact electrically connected to the p-type region, wherein the first and second contacts are disposed on a bottom side of the semiconductor structure; and at least one opening formed in the p-type region and the light emitting region, wherein the opening exposes a portion of the n-type region and wherein a connection between the n-type region and the first contact is disposed within the opening; wherein the first contact has a top surface in contact with the n-type region and a bottom surface opposite the top surface, wherein the bottom surface has a lateral extent larger than a lateral extent of the via.
