Patent ID: 8653529

Claim:
A semiconductor device comprising: a semiconductor die; a semiconductor integrated circuit formed in a front surface portion of the semiconductor die and comprising a light receiving element; an insulation film disposed on the semiconductor integrated circuit and having a recess portion on the light receiving element; a light shield film disposed on the insulation film and having an opening on the recess portion and a slit extending, in a plan view of the light shield film, from the recess portion toward outside of the recess portion, the entire light shield film being made in one plane, and the slit and the opening having different shapes, the slit in the light shield film being an opening or a dent made by removing a portion of the light shield film; a pad electrode disposed on the semiconductor die and connected to the semiconductor integrated circuit; a supporting substrate attached to the front surface portion of the semiconductor die; an adhesive layer disposed between the semiconductor die and the supporting substrate so as to attach the supporting substrate to the front surface portion of the semiconductor die; and a back surface wiring electrode formed on a back surface of the semiconductor die and connected to the pad electrode.
