Abstract:
1. A nitride semiconductor light emitting device including a conductive substrate formed of a semiconductor material, a first metal layer, a second conductivity-type semiconductor layer, an emission layer, and a first conductivity-type semiconductor layer, in this order, wherein the nitride semiconductor light emitting device additionally has an insulating layer which covers at least side surfaces of said second conductivity-type semiconductor layer, said emission layer and said first conductivity-type semiconductor layer, wherein said first metal layer comprises a first surface that is a surface of a second ohmic layer, and a second surface that is disposed opposite the first surface and is a surface of a first ohmic layer, wherein the first surface of the first metal layer has a first portion facing said second conductivity-type semiconductor layer, and a second portion on which said insulating layer is disposed, wherein a first portion of a first surface of said second conductivity-type semiconductor layer does not have said insulating layer thereon and is in contact with said first portion of said first surface of said first metal layer, and wherein a second portion of the first surface of said second conductivity-type semiconductor layer is not in contact with said first surface of said first metal layer, and the insulating layer covers the second portion of said first surface of said second conductivity-type semiconductor layer.
