Patent ID: 8823031

Claim:
A semiconductor light emitting device comprising: a semiconductor structure that includes an active region; a transparent electrically-conducting layer that is formed on or above an upper surface of said semiconductor structure; a dielectric film that is formed on or above an upper surface of said transparent electrically-conducting layer; and a metal reflecting layer that is formed on or above an upper surface of said dielectric film, wherein said dielectric film defines at least one opening to partially expose said transparent electrically-conducting layer therethrough, wherein said transparent electrically-conducting layer is electrically connected to said metal reflecting layer through said opening, wherein a barrier layer which is capable of preventing a deterioration of at least a part of the metal reflecting layer which faces the transparent electrically-conducting layer is partially formed covering said opening so that the barrier layer is interposed between said transparent electrically-conducting layer and the metal reflecting layer, further comprising a pad electrode is formed on or above an upper surface of said metal reflecting layer, wherein said pad electrode includes a plurality of smaller n-side electrodes that are dispersedly arranged.
