PURPOSE:To prevent creeping of a protective film to a mount surface without a rectangular jig to be inserted between semiconductor laser bars by closely arranging a plurality of semiconductor bars with the light emitting end face tilted and up on a flat supporting base and by depositing an insulating film. CONSTITUTION:Fixing jigs 3a, 3b are provided with an inclination of about 12 deg., and a plurality of semiconductor laser bars 1 are inserted therebetween in lamination with an electrode 6a at a side of a light emitting region 5 on the left side and fixed to a flat supporting base 4. A protective film is formed to an upper end side 7a on the semiconductor laser bar from an upper part through sputtering, etc. Then, a protective film is formed with a lower end side 7b up. According to this constitution, a protective film of a uniform film thickness can be formed all over the end side, thereby preventing creeping of the protective film on a mount surface. |
