METHOD OF MANUFACTURING STEM FOR OPTICAL SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a stem for optical semiconductor device, by which the stem for optical semiconductor device equipped with a heat dissipation portion having a high heat dissipation characteristic can be effectively produced and precisely manufactured. SOLUTION: The manufacturing method includes the steps of: preparing a metal plate 13 made by a structure in which a primary metal layer 10 is pinched between a lower side secondary metal layer 12a and an upper side secondary metal layer 12b; forming a structure in which an opening 12x is provided at a part of the upper side secondary metal layer 12b of the metal plate 13 by performing a press working to the metal plate 13; and erecting a primary metal layer 10 on the opening 12x of the upper side secondary metal layer 12b by performing a press working to the metal plate 13 to form a heat dissipation portion 20.
