| 英文摘要 | PURPOSE:To prevent the generation of a defective short circuit by obviating a movement and an adhesion to a P-N junction section of a conductive foreign matter by coating a surface section except the end surface of a resonator in a laser chip fixed to a support board with an insulating undercoat resin. CONSTITUTION:With a laser chip 1, a surface section except the end surface 5 of a resonator emitting laser beams 8 is coated with an undercoat resin 15. The undercoat resin 15 is attached adjoined to the end surface 5 of the resonator as much as possible, and considered so as to coat a P-N junction section exposed to the circumferential surface of the laser chip 1 as much as possible. A resist such as a photo-resist is applied to the end surface 5 section of the resonator in the laser chip 1 first, and dried, the undercoat resin 15 is applied automatically by a dispenser, etc., and the photo-resist is washed and removed by an organic solvent. Accordingly, a conductive foreign matter 6 is not in contact with most sections of the P-N junction even when the foreign matter 6 comes flying and adheres to the laser chip 1 after the laser chip is coated with the undercoat resin 15 from the outside. |
