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  40 a  and a well layer  40 b  narrower in bandgap than the barrier layer  40 a  in the stated order so that the number of barrier layers  40 a  and the number of well layers  40 b  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.

Claim (Index 9):
A method of manufacturing a group III nitride semiconductor light-emitting element, the method comprising:\n a first step of forming an n-type group III nitride semiconductor layer; a second step of forming, on the n-type group III nitride semiconductor layer, a group III nitride semiconductor laminated body obtained by alternately laminating a barrier layer and a well layer narrower in bandgap than the barrier layer in the stated order so that the number of barrier layers and the number of well layers are both N, where N is an integer; a third step of forming an AlN guide layer having a thickness of 0.5 nm or more and 2.0 nm or less, on the group III nitride semiconductor laminated body; and a fourth step of forming a p-type group III nitride semiconductor layer on the AlN guide layer, wherein, in the third step, (i) an AlGaN alteration layer is epitaxially grown using source gas including trimethylaluminum gas, trimethylgallium gas, and ammonia gas; (ii) supply of the trimethylaluminum gas and the trimethylgallium gas is then stopped to interrupt the epitaxial growth; and (iii) the AlGaN alteration layer is exposed to a carrier gas atmosphere having hydrogen as a main component, to at least partially remove and alter the AlGaN alteration layer to the AlN guide layer, and cause a remaining part of the AlGaN alteration layer to be a final barrier layer.
