Abstract:
1. A method of producing a solid-state imaging device comprising the steps of: forming a light receiving unit and a pixel circuit in a first surface side of a substrate; grinding a second surface side of said substrate to make said substrate thinner; forming a transparent first insulation film on said second surface of said substrate; forming a second insulation film on said first insulation film; and injecting charges having the same polarity as a signal charge in an interface between said first insulation film and said second insulation film or in said second insulation film, wherein, in the steps of forming said first insulation film and said second insulation film, said first insulation film and said second insulation film are formed to have thicknesses so as to obtain a transmittance of an incidence light higher than when using only said first insulation film and wherein the light receiving unit extends only partially into said substrate from the first surface side of the substrate towards the second surface side of said substrate.
