Group iii nitride semiconductor light-emitting device

Abstract

A face-up-type Group III nitride semiconductor light-emitting device includes a growth substrate, an n-type layer, a light-emitting layer, a p-type layer, an n-electrode including a bonding portion and a wiring portion, a p-electrode including a bonding portion and a wiring portion, and a first insulating film. The n-type layer, the light-emitting layer, and the p-type layer are sequentially stacked on the growth substrate, and the n-electrode and the p-electrode are formed on the first insulating film. A groove having a depth extending from a top surface of the p-type layer to the n-type layer is formed in at least one region selected from a region directly below the wiring portion of the n-electrode and a region directly below the wiring portion of the p-electrode. The wiring portion, which is formed in the groove, is located at a level lower than that of the light-emitting layer.

Dependencies are inferred from the claim text.
