| 摘要 |
A nitride semiconductor light emitting device includes a substrate, a first conductivity type nitride semiconductor layer disposed on the substrate and including a plurality of V-pits placed in a top surface thereof, a silicon compound formed in the vertex region of each of the V-pits, an active layer disposed on the first conductivity type nitride semiconductor layer and including depressions conforming to the shape of the plurality of V-pits, and a second conductivity type nitride semiconductor layer disposed on the active layer. The nitride semiconductor light emitting device, when receiving static electricity achieves high resistance to electrostatic discharge (ESD) since current is concentrated in the V-pits and the silicon compound placed on dislocations caused by lattice defects.
