Abstract:
A light emitting semiconductor device comprising a semiconductor substrate, a first conductivity type epitaxial layer and a second conductivity type epitaxial layer or a high resistance epitaxial layer stacked one upon another, a V-groove having a V-shaped cross-section on the semiconductor, wherein an inclined surface of said V-groove is formed from the first conductivity type epitaxial layer to the second conductivity type epitaxial layer or the high resistance epitaxial layer, a bottom of the V-groove lies in said first conductivity type epitaxial layer, a side wall of the V-groove is in contact with the second conductivity type epitaxial layer or the high resistance epitaxial layer, wherein the first conductivity type epitaxial layer, the second conductivity type epitaxial layer or the high resistance layer are present outside the V-groove and an active layer formed inside the bottom of said V-groove on the first conductivity type epitaxial layer.
