Patent ID: 6979581

Claim:
A method of manufacturing a semiconductor light emitting device comprising steps of; (a) forming a semiconductor laminated part comprising a light emitting layer forming portion and a semiconductor layer for selective oxidation for forming a current injection region on a substrate, (b) etching away a part of said semiconductor laminated part such that said current injection region and its peripheral region would be left in mesa-shape, (c) forming a predetermined range of current injection region by oxidizing said semiconductor layer for selective oxidation etched in mesa-shape from its periphery toward its center, while observing by a microscope an oxidation condition of said semiconductor layer for selective oxidation from a surface side of said semiconductor laminated part, wherein the step of oxidizing said semiconductor layer for selective oxidation further comprises steps of: setting said substrate on which said semiconductor laminated part is grown in a chamber, and oxidizing said semiconductor layer for selective oxidation by supplying vapor which is stable at about 400° C. to 500° C. around said semiconductor layer for selective oxidation; and (d) forming electrodes for electrical connection on both sides of said semiconductor laminated part; and wherein a vapor supply pipe having a heater is provided on said chamber and said vapor is supplied around said semiconductor layer for selective oxidation by introducing a vapor into said chamber through said vapor supply pipe.
