Patent ID: 10573783

Abstract:
A group III nitride semiconductor light-emitting element having longer element life than conventional group III nitride semiconductor light-emitting elements and a method of manufacturing the same are provided. A group III nitride semiconductor light-emitting element 100 comprises, in the following order: an n-type group III nitride semiconductor layer 30; a group III nitride semiconductor laminated body 40 obtained by alternately laminating a barrier layer 40a and a well layer 40b narrower in bandgap than the barrier layer 40a in the stated order so that the number of barrier layers 40a and the number of well layers 40b are both N, where N is an integer; an AlN guide layer 60; and a p-type group III nitride semiconductor layer 70, wherein the AlN guide layer 60 has a thickness of 0.5 nm or more and 2.0 nm or less.
