Patent ID: 7518800

Claim:
A solid state imaging device including a semiconductor substrate with light receiving elements formed thereon, and a light shielding film with openings above said light receiving elements and for covering at least a part of said semiconductor substrate, comprising: inner lenses each located above one of said openings and having an upper convex lens surface and a lower convex lens surface which projects into said opening, said upper convex lens surface converging incident light to a diameter smaller than a maximum diameter of said lower convex lens surface, said lower convex lens surface having a light exit surface at the bottom from which said incident light exits toward said light receiving elements; wherein said upper convex lens surface has a maximum diameter larger than said maximum diameter of said lower convex lens surface; and a light shielding film on each of said inner lenses and covering said lower convex lens surface except said light exit surface, for reflecting said incident light to said light exit surface.
