Patent ID: 8258048

Claim:
A method of fabricating a semiconductor laser device, comprising steps of: preparing a semiconductor substrate provided with plural growth inhibiting portions including defect concentration regions on prescribed regions of the principal surface; growing a semiconductor element layer having a principal surface inclined with respect to the principal surface of said semiconductor substrate and including an emission layer on the principal surface of said semiconductor substrate through said growth inhibiting portions; and forming a projection portion functioning as a current path toward said emission layer on said principal surface of said semiconductor element layer, wherein said projection portion is formed on a noncentral portion between said growth inhibiting portions, said step of preparing said semiconductor substrate includes a step of preparing said semiconductor substrate on which a first growth inhibiting portion and a second growth inhibiting portion of said growth inhibiting portions are arranged at a prescribed interval, and said step of growing said semiconductor element layer includes a step of growing said semiconductor element layer having a concave principal surface between said first growth inhibiting portion and said second growth inhibiting portion.
