英文摘要 | PURPOSE:To implement mass production, by performing etching with macromolecular films, which are formed on the electrode surface of a semiconductor laser wafer, as mask materials, forming end surfaces for taking out emitted light outputs, depositing an insulating film on the one entire surface, and removing the insulating film and the macromolecular films, which are formed on the electrode. CONSTITUTION:On an N-type substrate crystal 1, a double heterojunction epitaxial crystal layer 2 is grown. A P-type electrode and an N-type electrode 4 are formed. A macromolecular resin film 5 is formed on the P-type electrode 3. A pattern for an end-surface machining region is printed and developed. Thus the stripe shaped macromolecular films 5 are formed. With the macromolecular films 5 as masks, the P-type electrode 3 is etched away. The crystal 2 is etched to a depth reaching the substrate crystal Approximately vertical grooves, i.e., end surfaces for taking out light outputs emitted from a laser, are formed. Then, an insulating film 6 is deposited. The macromolecular resin films 5 on the electrode surface are removed and a chip is obtained. |
