Patent ID: 8138001

Claim:
A semiconductor light-emitting device, comprising: a compound semiconductor layer formed by laminating at least a first conductive type first clad layer formed from a group III-V compound semiconductor, a light-emitting layer formed from either a first conductive type or an opposite second conductive type group III-V compound semiconductor, and a second conductive type second clad layer formed from a group III-V compound semiconductor, a plurality of first ohmic electrodes formed on said first clad layer, a plurality of second ohmic electrodes formed on said second clad layer, a transparent conductive film that is foimed on said first clad layer of said compound semiconductor layer and is conductively connected to said first ohmic electrodes, a bonding electrode formed on said transparent conductive film, and a support plate that is positioned on a side of said second clad layer of said compound semiconductor layer and is conductively connected to said second ohmic electrodes, in which said first ohmic electrodes are positioned by being dispersed across a surface of said first clad layer, a plurality of depressions are provided within a bonding surface of said second clad layer on a side of said support plate, and said second ohmic electrodes are positioned within bottom portions of said depressions, said compound semiconductor layer is provided with a current diffusion layer that coats said bonding surface of said second clad layer, surfaces of said second ohmic electrodes within said depressions, and side portions of said depressions, and said support plate is bonded to said current diffusion layer.
