Abstract:
1. A semiconductor light emitting device, comprising: a light emitting structure including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer sequentially laminated therein; and first and second electrodes electrically connected to the first and second conductivity-type semiconductor layers, respectively, wherein the second electrode comprises: a reflective pad portion disposed in a region of an upper surface of the second conductivity-type semiconductor layer; a transparent electrode layer disposed on the second conductivity-type semiconductor layer and having an opening encompassing the reflective pad portion such that the transparent electrode layer is not in contact with the reflective pad portion; a reflective finger portion extending from the reflective pad portion and having at least a portion thereof disposed on the transparent electrode layer; an electrode pad portion covering the reflective pad portion and disposed to be in contact with the transparent electrode layer; and an electrode finger portion covering an upper surface of the reflective finger portion and disposed to be in contact with the transparent electrode layer, wherein a metal layer is disposed at an interface between the reflective finger portion and the transparent electrode layer.
