Abstract:
A method of fabricating a nitride semiconductor light-emitting device which uses as a light emitting layer an indium-containing group-III nitride semiconductor layer of a multi-phase structure composed of a main phase and sub-phases having different indium contents, comprising the steps of:thermally treating said light emitting layer at a heat treatment temperature in a range of from 950 to 1200Â° C.; cooling said light emitting layer from said heat treatment temperature to 950Â° C. at a rate of 20Â° C. or more per minute; and cooling said light emitting layer from 950Â° C. to 650Â° C. at a rate of 20Â° C. or less per minute, thereby forming strained layers at boundaries between said main phase and said sub-phases.
