description A semiconductor light emitting device includes a conductive substrate and a first metal layer disposed on the substrate. The first metal layer is formed so as to be electrically connected with the substrate, and the first metal layer includes an Au based material. A joining layer is formed on the first metal layer. The joining layer includes a second metal layer including Au and a third metal layer including Au. A metallic contact layer and an insulating layer are formed on the joining layer. A semiconductor layer is formed on the metallic contact layer and the insulating layer and includes a red-based light emitting layer. An electrode is formed on the semiconductor layer and is made of metal. The insulating layer includes a patterned aperture, and at least a part of the metallic contact layer is formed in the aperture.
