Patent ID: 8912559

Claim:
A face-up-type Group III nitride semiconductor light-emitting device, comprising: 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; a first insulating film; and a second insulating film, the n-type layer, the light-emitting layer, and the p-type layer being sequentially stacked on the growth substrate, the n-electrode and the p-electrode being formed on the first insulating film, and a portion of each of the n-electrode and the p-electrode other than the bonding portion being covered with the second insulating film, wherein the light-emitting device includes a reflective film incorporated in the first insulating film in a region directly below each of the n-electrode and the p-electrode, the reflective film comprising a material exhibiting a reflectance for light of emission wavelength higher than that of the wiring portion, wherein 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 of a region directly below the wiring portion of the n-electrode and a region directly below the wiring portion of the p-electrode, and wherein the reflective film which is formed in the groove is located at a level lower than that of the light-emitting layer.
