ABSTRACT:
In order to position an optical semiconductor element in high accuracy and to readily fabricate the same, step is formed on an upper surface of a forward end of an electrode (123) projecting from a lead frame. A submount (102) is previously soldered to a lower stage surface (125), while solder (172) is applied to its upper surface. A collet (61) which is softly supported by a spring (63) in the vertical direction suctionally holds a laser diode element (101) and approaches the electrode (123) from above, to be stopped when its leg portion (61b) comes into contact with an upper stage surface (126). Thus, the laser diode element (101) is precisely positioned. In this state, the solder (172) is heated and cooled, to solder the laser diode element (101) to the submount (102). The laser diode element (101) molded with transparent resin, to be easy to fabricate.
