Abstract:
1. A semiconductor device, comprising: a semiconductor substrate having a first surface and a second surface at an opposite side of the first surface; a light-receiving portion provided on the first surface of the semiconductor substrate; an electrode, provided on the first surface of the semiconductor substrate, electrically connecting to the light-receiving portion; a penetrating wiring layer, provided at the semiconductor substrate to join the first surface and the second surface, electrically connecting to the electrode; a light-transmissive protective substrate disposed immediately above the light-receiving portion via only a gap, to cover the first surface of the semiconductor substrate; a protective film, formed on a first surface of the light-transmissive protective substrate at an opposite side of a second surface of the light-transmissive protective substrate facing the first surface of the semiconductor substrate in contact with the first surface of the light-transmissive protective substrate, having an opening corresponding to the light-receiving portion; and a light-transmissive nonmetallic protective film provided to cover the first surface of the light-transmissive protective substrate including on the protective film, the light-transmissive nonmetallic protective film having a thickness thinner than that of the protective film, wherein the protective film has conductivity.
