Patent ID: 8222656

Claim:
A semiconductor light emitting device, comprising: a plurality of compound semiconductor layers comprising a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer; a first electrode under the first conductive type semiconductor layer; a second electrode layer having an unevenness on the second conductive type semiconductor layer, the second electrode layer being positioned opposite to the first electrode, having the plurality of compound semiconductor layers therebetween; and a conductive support member on the second electrode layer, the conductive support member having a width which is larger than a width of the second conductive type semiconductor layer, wherein the unevenness of the second electrode layer is disposed between the second conductive type semiconductor layer and the conductive support member, wherein the second electrode layer comprises a reflection layer and reflects light emitted by the active layer to a surface direction of the first conductive type semiconductor layer, and wherein the second conductive type semiconductor layer comprises a second unevenness and the second unevenness corresponds to the unevenness of the second electrode layer, and the second conductive type semiconductor layer is directly disposed on the second electrode layer.
