Patent ID: 8866178

Claim:
A light emitting device comprising: a conductive support member; a first conductive layer on the conductive support member; a second conductive layer on the first conductive layer; an insulation layer between the first conductive layer and the second conductive layer; a light emitting structure that includes a second semiconductor layer on the second conductive layer, a first semiconductor layer, and an active layer between the first semiconductor layer and the second semiconductor layer, the first semiconductor layer having a first surface, wherein the first conductive layer includes at least one conductive via that passes through the second conductive layer, the second semiconductor layer and the active layer, and a first surface of the at least one conductive via is provided into the first semiconductor layer, wherein the insulation layer substantially surrounds a side wall of the conductive via, wherein the conductive via includes an inclined surface, and wherein the first surface area of the first semiconductor layer has a surface roughness; and a reflective layer formed between the side wall of the conductive via and the insulation layer, wherein the reflective layer is formed on the inclined surface, and the reflective layer is directly on the insulation layer.
