A method of manufacturing an optical module package, which comprises the steps of, attaching a first member to a frame by means of silver-brazing to obtain a frame structure, applying an Au plating to the frame structure applied with the silver-brazing, and soldering a second member to the frame structure applied with the Au plating, wherein the method further comprises the steps of subjecting the frame structure to a high temperature dehydrogenation treatment of heating the frame structure in an non-oxidizing atmosphere at a temperature of 340.degree. C. or more for 10 minutes or more after the silver-brazing step and before the Au plating step, and subjecting the frame structure to a low temperature dehydrogenation treatment of heating the frame structure in an non-oxidizing atmosphere at a temperature ranging from 240.degree. C. to 260.degree. C. for 5 minutes or more after the soldering step.

Optical module package and method for manufacturing the same

A package for optical semiconductor device comprising a metallic frame having a side wall provided with an optical fiber-securing portion for securing an optical fiber to be introduced through the side wall, and a metallic bottom plate for mounting the optical semiconductor device thereon. The metallic frame is provided at a lower portion of the side wall thereof with securing parts for securing the package to a substrate, each securing part outwardly extending in a direction parallel with the metallic bottom plate. The level of bottom face of the metallic bottom plate is made lower than that of the bottom face of the securing parts. The securing parts are integrally formed with the metallic frame.
