LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

Disclosed is a light-emitting device (1) comprising a buried current blocking layer (9) wherein the oxygen concentration in at least a part of the current blocking layer (9) is higher than the oxygen concentration of a light-emitting layer and the current blocking layer (9) has a thickness of 5-100 nm. The light-emitting device (1) comprises an etching stop layer (24) below the current blocking layer (9), and the etching stop layer (24) has oxidation resistance. This light-emitting device (1) is improved in the current-narrowing effect, thereby achieving a high output with a low forward voltage. Also disclosed is a method for manufacturing such a light-emitting device (1).
