Patent ID: 8624288

Claim:
A light emitting device, comprising: a supporting layer having a metal material; a metal layer comprising a first layer on the supporting layer, a second layer on the first layer, and a third layer on the second layer; a first electrode on the metal layer, the first electrode comprising a reflective material; a semiconductor structure having nitride material on the first electrode layer, the semiconductor structure comprising an n-type layer, an active layer on the n-type layer, and a p-type layer on the active layer; a passivation layer between the semiconductor structure and the metal layer; and a second electrode on the n-type layer of the semiconductor structure, wherein the passivation layer and the first electrode are in contact with at least a part of a top surface of the metal layer, and the metal layer is disposed between the first electrode layer and the supporting layer, and between the passivation layer and the supporting layer, wherein the semiconductor structure includes a light-extraction structure.
