<P>PROBLEM TO BE SOLVED: To provide a semiconductor device which can prevent damage to a light-receiving surface and deterioration of light-receiving characteristics, and has high light reception sensitivity. <P>SOLUTION: In the semiconductor device 1, an optical semiconductor element 10, a circular metal plate 20, a metal plate 30 and bumps 41, 42 are sealed with a resin 50. The bottom surfaces of the circular metal plate 20 and the metal plate 30 are provided on a common virtual plane. The top surface of the optical semiconductor element 10 is covered with the resin 50 provided on one side for the virtual plane. A light-receiving portion 13 of the optical semiconductor element 10, and the bottom surfaces of the circular metal plate 20 and the metal plate 30 are not covered with the resin 50, but exposed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
