Abstract:
1. A flip-chip type light emitting semiconductor device which comprises a light-transmitting substrate, a semiconductor layer deposited on said light-transmitting substrate, and an n-electrode and a p-electrode formed at the semiconductor layer side against said light-transmitting substrate, and which radiates light from said light-transmitting substrate side, comprising: a contact layer which is the uppermost layer of said semiconductor layer; a first electrode layer which is formed on said contact layer and supplies electric current to said contact layer; an insulation protection film which is formed on said first electrode layer and transmits light; a reflection film which is formed on said insulation protection film, made of metal and has high reflectivity to light; and a second electrode layer which is formed on said reflection film and contacts to at least a portion of said first electrode layer.
