Patent ID: 7972952

Claim:
A method for manufacturing a compound semiconductor light-emitting device, which comprises steps (a) to (c) shown below: (a) a step of manufacturing a semiconductor wafer by stacking an n-type semiconductor layer, a light-emitting layer and a p-type semiconductor layer, that are made of a gallium nitride-based compound semiconductor, on a substrate, the n-type semiconductor layer and the p-type semiconductor layer being stacked so as to interpose the light-emitting layer therebetween, (b) a step of stacking an amorphous IZO film on the p-type semiconductor layer, and (c) a step of crystallizing the amorphous IZO film, wherein the step of crystallizing the amorphous IZO film is performed by a heat treatment at a temperature of from 700° C. to 900° C. in an O 2 free atmosphere.
