Patent ID: 7675077

Claim:
A light-emitting diode, comprising: a conductive substrate including a first surface and a second surface opposite to the first surface; a metal bonding layer deposed on the first surface of the conductive substrate; a reflective metal layer deposed on the metal bonding layer; a transparent conductive layer deposed on the reflective metal layer; an N-type semiconductor layer deposed on the transparent conductive layer; an N-type contact layer deposed between a portion of the N-type semiconductor layer and a portion of the transparent conductive layer and embedded in the transparent conductive layer; a metal material layer deposed on the N-type contact layer and embedded in the transparent conductive layer; an active layer deposed on the N-type semiconductor layer; a P-type semiconductor layer deposed on the active layer; a window layer deposed on the P-type semiconductor layer, wherein a thickness of the window layer is substantially at least 50 μm, and the window layer is composed of a transparent conductive material; and a P-type electrode deposed on the window layer.
