Patent ID: 8772803

Claim:
A semiconductor light-emitting device, comprising: an electrode layer; a light-emitting structure, the light-emitting structure comprising a plurality of semiconductor layers wherein an uppermost layer of the plurality of semiconductor layers comprises a N type semiconductor layer; a channel layer along an edge of the electrode layer and having a top surface and a bottom surface opposite to each other and parallel to each other; an adhesion layer under the electrode layer; and an electrode on the light-emitting structure, wherein the electrode comprises: an ohmic contact layer that directly contacts a top surface of the N-type semiconductor layer; a first barrier layer on the ohmic contact layer; a conductive layer comprising copper on the first barrier layer; a second barrier layer on the conductive layer; and a bonding layer on the second barrier layer, wherein the top surface of the channel layer is spaced apart from a side surface of the uppermost layer of the plurality of semiconductor layers, and wherein at least a portion of the top surface of the channel layer extends horizontally from a side surface of the light-emitting structure toward a side surface of the adhesion layer.
