Abstract:
1. A method for fabricating a semiconductor light emitting device comprising the steps of: forming a plurality of band-like concave portions on top of a first GaN based semiconductor layer with predetermined intervals therebetween; forming a second GaN based semiconductor layer by epitaxial lateral overgrowth on the projecting portions formed between the concave portions as starting points, and thereby forming an air layer between the bottom surface of the second GaN based semiconductor layer and the concave portion; forming a layered structure comprising an n-type GaN based semiconductor layer, an active layer, and a p-type GaN based semiconductor layer, on the second GaN based semiconductor layer; forming an n-type electrode on the n-type GaN based semiconductor layer that is exposed by removing a portion of the layered structure; and forming a transparent p-type electrode serving as an emission detection surface on the p-type GaN based semiconductor layer.
