Semiconductor devices and method for manufacturing the same.

摘要

A semiconductor laser element (133) is mounted to a heat sink (132) which is formed as one body with a stem (131) and is covered with a cap (138) mounted to the stem (131). An opening (138a) through which a fluid material (105) is filled into the cap (138) is provided on the top face of the cap (138). The opening (138a) is closed with a hologram glass (139).
