Patent ID: 7655485

Claim:
A method for fabricating a nitride-based semiconductor light emitting device, including: forming at least a first nitride-based semiconductor layer, including an active layer of said nitride-based semiconductor light emitting device; and forming a current narrowing structure on said at least a first nitride-based semiconductor layer, comprising: forming, on said at least a first nitride-based semiconductor layer, a mask of a material including nitrogen as a constituent element, and then regrowing at least a second nitride-based semiconductor layer in an opening of said mask, wherein said regrowing at least a second nitride-based semiconductor layer in an opening of said mask comprises: growing said at least a second nitride-based semiconductor layer in said opening at a growth temperature which is higher than a temperature where the material of said mask is decomposed, while growing said at least a second nitride-based semiconductor layer, suppressing decomposition of the mask by having a partial pressure of nitrogen that balances separation of nitrogen from said mask with absorption of nitrogen to said mask.
