| 英文摘要 | PURPOSE:To contrive to make assembly work efficient by facilitating the discrimination of the direction for stem mounting by a method wherein a sign, figure, and pattern, etc. discriminating one end surface are arranged on one electrode surface of the titled element. CONSTITUTION:A GaAlAs double hetero grown layer 2 is grown on an N type GaAs substrate 1, a P type electrode 3 is provided on the layer 2, and an N type electrode 4 is provided on the opposite surface of the substrate 1, thus constructing a wafer of the semiconductor laser. One electrode 3 of this wafer is coated with photo resist OMR (trade name), and exposure and development are performed by means of a photo mask having a marker 10 for discrimination, resulting in the state that only the part of the marker 10 has come off. Only the part of the marker 10 of this wafer is removed by etching, and a stripe 5 is formed by cleavage, thereby constructing the semiconductor laser 1 When the laser 11 is built on the stem 24, it is mounted between a low reflection film 21 and a high reflection film 22 on a sub-mount 23 according to the marker 10, and accordingly the assembly work is improved. |
