Abstract:
1. A solid-state imaging device comprising: an imaging area including a plurality of light receiving portions formed on a semiconductor substrate; a multi-layered interconnect layer disposed on the plurality of light receiving portions, the multi-layered interconnect layer including metal interconnects and insulating films; first lenses formed on the multi-layered interconnect layer in one-to-one relationship with the light receiving portions; second lenses formed above the first lenses; and a transparent film formed on the second lenses, wherein a refractive index of the transparent film is smaller than a refractive index of the second lenses, a thickness of the second lenses is greater than a thickness of the first lenses, the plurality of light receiving portions, the first lenses, and the second lenses are disposed two-dimensionally in a vertical direction and a horizontal direction in the imaging area, the second lenses adjacent to each other in the horizontal direction are in connection with each other, and an upper face of each of the second lenses has a curvature smaller in the horizontal direction than in a diagonal direction.
