Patent ID: 7786515

Claim:
A solid-state imaging device, comprising: a semiconductor substrate with an imaging region having a light receiving section; a dielectric film formed on the semiconductor substrate having a portion that covers the light receiving section; an interlayer insulation film formed on the dielectric film; a first diffusion protection film formed on a surface of the interlayer insulation film facing away from the substrate and covering at least the light receiving section, the first diffusion protection film having a first wiring groove therein filled with a metal element; a first inter-wiring insulation film formed on the first diffusion protection film; a second diffusion protection film formed on a surface of the first inter-wiring insulation film facing away from the semiconductor substrate; a second inter-wiring insulation film formed on the second diffusion protection film; an opening over the light receiving section and which extends through the second inter-wiring insulation film, the second diffusion protection film, and the first inter-wiring insulation film, but not through the first diffusion protection film; and a lens aligned with the opening.
