Abstract:
1. A Group III nitride semiconductor light-emitting device, comprising: a conductive support; a p-electrode disposed on the support; a semiconductor layer disposed on the p-electrode, the semiconductor layer comprising at least a p-layer, a light-emitting layer, and an n-layer disposed in this order from the p-electrode, each of the p-layer, the light-emitting layer, and the n-layer being formed of a Group III nitride semiconductor, and an n-electrode being disposed on the n-layer; a device isolation trench which is formed along the outer periphery of the semiconductor layer and which provides the semiconductor layer with a mesa shape; and an insulation film continuously provided on first to third regions, the first region being an outer peripheral region of the n-layer, the second region being the side surface of the trench, and the third region being the bottom surface of the device isolation trench, wherein the n-electrode comprises a pad portion to which a bonding wire is to be connected, a contact portion which is disposed at a distance from the pad portion and which is partially or fully disposed on the n-layer, and an outer peripheral wire trace portion which extends so as to contour the periphery, to thereby connect the pad portion with the contact portion, and wherein a part of a width of the outer peripheral wire trace portion is disposed on the insulation film, and a remaining part of the width of the outer peripheral wire trace portion is disposed on the n-layer over the total length in a longitudinal direction.
