Patent ID: 8513679

Claim:
A semiconductor light-emitting device, comprising: a conductive support member; a reflective layer disposed above the conductive support member; an adhesion layer between the reflective layer and the conductive support member; a light-emitting structure disposed above the reflective layer, the light-emitting structure comprising a first conductive type semiconductor layer, an active layer disposed on the first conductive type semiconductor layer, and a second conductive type semiconductor layer disposed on the active layer; an electrode disposed on the light emitting structure; a channel layer disposed along a bottom edge of the light emitting structure; and a current blocking layer that corresponds to the electrode, wherein the adhesion layer has a top surface including a plurality of first protrusion portions and a plurality of first recess portions, wherein the reflective layer has a bottom surface including a plurality of second protrusion portions and a plurality of second recess portions, wherein one of the plurality of second protrusions of the reflective layer under the current blocking layer is disposed on at least one of the plurality of first recess portions or the plurality of first protrusion portions of the adhesion layer, and wherein the top surface of the adhesion layer contacts the bottom surface of the channel layer.
