Patent ID: 8415705

Claim:
A semiconductor light emitting device comprising: a light emitting structure including a first conductive semiconductor layer, an active layer and a second conductive semiconductor layer; a channel layer on the light emitting structure, having protrusions; an electrode layer on the light emitting structure and the channel layer; and a conductive support member on the electrode layer, wherein the channel layer is formed along the peripheral portion of an upper surface of the light emitting structure, and the electrode layer is formed at an inner side of the upper surface of the light emitting structure, wherein the protrusions of the channel layer are formed at an under surface of the channel layer such that the protrusions protrude toward the light emitting structure, wherein the first conductive semiconductor layer includes a roughness pattern on a lower surface, wherein the electrode layer includes a protrusion directly contacted with the light emitting structure, and wherein the protrusion of the electrode layer is protruded toward the light emitting structure.
