英文摘要 | PURPOSE:To enhance the reliability of the titled device by preventing the reaction of both of the followings by providing an Mo or W barrier between a III-V group compound semiconductor crystal of GaAlAs, InGaAsP series or the like and a solder of Au or Au-Sn, In-Sn, or Pb-Sn series. CONSTITUTION:A P type InP 5 and P type InGaAsP 6 are laminated on an InGaAsP active layer 3 filled with a P type InP 2 on an N-InP substrate 1, and an electrode window is provided in an SiO2film 7. Next, Cr of about 150-500Angstrom , Mo or W of about 1,000-2,000Angstrom , and Au of 1,000-10,000Angstrom are laminated by successive evaporation. Loading to a heat radiator produces the electrode structure of ohmic electrode and adhesion layer-barrier metallic laser-Au or solder layer. Even under high temperature and high output, the reaction of the solder and the laser constituent or the rise in operating current due to the diffusion of solder into the laser element never occurs. |
