Abstract

The present invention relates to a III-nitride semiconductor light emitting device comprising a plurality of III-nitride semiconductor layers including an active layer emitting light by recombination of electrons and holes, the plurality of III-nitride semiconductor layers having a p-type III-nitride semiconductor layer at the top thereof, a SiCN(a≧0,b>0,c≧0) layer grown on the p-type III-nitride semiconductor layer, the SiCNlayer having an n-type conductivity and a thickness of 5 Å to 500 Å for the holes to be injected into the p-type III-nitride semiconductor layer by tunneling, and a p-side electrode formed on the SiCNlayer. According to the present invention, a SiCN(a≧0,b>0,c>0) layer which can be doped with a high concentration is intervened between a p-type nitride semiconductor layer and a p-side electrode. Therefore, the present invention can solve the conventional problem.
