Abstract
A semiconductor device includes a first surface faced to a mounting board when the semiconductor device is placed over the mounting board and a second surface opposed to the first surface. The semiconductor device also includes a position reference portion which is provided in an area including sides of the second surface and which has an optical reflection factor different from that of the mounting board.
