SEMICONDUCTOR DEVICE AND OPTICAL DEVICE USING THE SAME

摘要

PURPOSE: A semiconductor device and an optical device using the same are provided to improve the mounting efficiency and the adhering strength by forming the first surface and the second surface on a main surface. CONSTITUTION: A semiconductor device includes a semiconductor element and a support member. The support member includes a recess for housing the semiconductor element. The support member further includes lead electrodes and a support part holding the lead electrodes so that a surface of each of the lead electrodes is exposed in the bottom of the recess. The support member has at least a first surface(1a) disposed adjacent to the recess and a second surface(1b) disposed adjacent to and offset from the first surface.
