PURPOSE:To prevent the generation of an optical axis misalignment by fixing a package by an Sn-Sb alloy contg. prescribed % of Sn or Pb-Sb alloy contg. specific % of Pb to a holder which holds an optical fiber and a lens, thereby fixing the semiconductor device. CONSTITUTION:A laser diode element 11 is mounted on the package 12 and a laser beam is condensed through the transparent window of the package 12 by a SELFOC lens 14 and is introduced to the optical fiber 17 positioned in the central part of an optical fiber ferrule 16. The package 12, the lens 14 and an optical fiber ferrule 16 are so fixed in a cylindrical holder 15 as to align the optical axes. This package 12 and the holder 15 are joined by the Sn 3 to 10% Sb alloy or Pb 5 to 15% Sb alloy 13. A method using a high-frequency waveguide is adopted as the heating method for this joining method and the joining is executed by using a flux in order to improve the wettability of the Sn 3 to 10% Sb alloy or Pb 5 to 15% Sb alloy. |
