Abstract:
1. A pn-junction compound semiconductor light-emitting device comprising (i) a stacked structure including a light-emitting part composed of aluminum gallium indium phosphide, said light-emitting part comprising a light-emitting layer, a lower clad layer and an upper clad layer, and (ii) a light-permeable substrate for supporting the stacked structure, the stacked structure including a conductive boron containing Group III-V compound semiconductor layer formed on the light-emitting part, wherein the light permeable substrate is joined to the stacked structure through the boron containing Group III-V compound semiconductor layer, and wherein the respective layers constituting the light-emitting device are arranged in the order of the light-permeable substrate, the conductive boron containing Group III-V compound semiconductor layer, the upper clad layer, the light-emitting layer and the lower clad layer.
