Patent ID: 7507945

Claim:
A solid state imaging device including a semiconductor substrate with a plurality of light receiving elements formed thereon, a light shielding layer for covering an upper surface of said semiconductor substrate and having openings formed at positions corresponding to said light receiving elements, a concave microlens-forming layer for covering upper surfaces of both said light shielding layer and said light receiving elements and having cone-shaped concave lens surfaces formed at positions corresponding to said light receiving elements, and a convex microlens-forming layer located above said concave microlens-forming layer and having convex lens surfaces formed at positions corresponding to said light receiving elements, said concave lens surface comprising: an incident surface lying at the lowermost part of said concave lens surface and for focusing light rays toward said light receiving element; and a reflecting surface extending upwards from a rim of said incident surface and for totally reflecting light rays coming from said convex lens surface toward said incident surface, wherein said incident surface focuses said totally reflected light rays toward said light receiving element.
