  • Patent number: 9490412
    Abstract: A Peltier module for laser diode that can be mounted with high melting point solder is provided. A Peltier module for laser diode includes: a heat dissipation-side substrate; a heat dissipation-side electrode; a p-type thermoelectric conversion element and an n-type thermoelectric conversion element; a solder joint layer; and Ni-containing layers. The solder joint layer is disposed between the heat dissipation-side electrode and each of the p-type and n-type thermoelectric conversion elements, and includes Ni intermetallic compound containing Au and Sn, Au5Sn intermetallic compound, and a eutectic composition including Au5Sn intermetallic compound and AuSn intermetallic compound. The Ni-containing layer is disposed between the solder joint layer and the heat dissipation-side electrode and between the solder joint layer and each of the p-type and n-type thermoelectric conversion elements. The solder joint layer has a eutectic ratio of 15.1% or less.
