Patent ID: 7884377

Claim:
A light emitting device comprising: at least one light emitting stack including first and second conductivity type semiconductor layers and an active layer disposed therebetween, the light emitting stack having first and second surfaces defined by the first and second conductivity type semiconductor layers, respectively to oppose each other and side surfaces interposed between the first and second surfaces; a first contact formed on the first surface of the light emitting stack to contact the first conductivity type semiconductor layer; a second contact formed on the second surface of the light emitting stack to contact the second conductivity type semiconductor layer; a first insulating layer formed on the second surface excluding a portion where the second contact is formed and the side surfaces of the light emitting stack; a conductive layer connected to the second contact and extended along one of the side surfaces of the light emitting stack to have an extension portion adjacent to the first surface; and a substrate structure formed to surround the side surfaces and the second surface of the light emitting stack.
