Patent ID: 10600933

Abstract:
A light-emitting device can include a conductive support structure comprising a metal; a GaN-based semiconductor structure disposed on the conductive support structure, the GaN-based semiconductor structure including a p-type GaN-based layer, a GaN-based active layer and an n-type GaN-based layer, in which the GaN-based semiconductor structure has a first surface, a side surface and a second surface, in which the first surface, relative to the second surface, is proximate to the conductive support structure, in which the second surface is opposite to the first surface, in which the conductive support structure is thicker than the p-type GaN-based semiconductor layer, and the conductive support structure is thicker than the n-type GaN-based semiconductor layer; a p-type electrode disposed on the conductive support structure; an n-type electrode disposed on the second surface of the GaN-based semiconductor structure; and a passivation layer disposed on the side surface and the second surface of the GaN-based semiconductor structure.
