Abstract
A solid-state imaging device includes: an on-chip color filter having color filter components formed to correspond to pixels; light-shielding members each formed at the boundary of adjacent color filter components; and lenses concave toward a light incident direction, each formed directly below a corresponding one of the color filter components by self-alignment with the light-shielding members as a mask.
Claims15
A solid-state imaging device comprising:
- an on-chip color filter having color filter components corresponding to pixels;
- light-shielding members each positioned at the boundary of adjacent color filter components;
- a first set of lenses concave toward a light incident side of the solid-state imaging device, each positioned to directly correspond to one of the pixels and one of the color filter components by self-alignment with the light-shielding members;
- and
- a frame-shaped first insulating film formed on an object side of the light-shielding members and configured to have a triangular sectional shape, and gapless on-chip microlenses are formed on the on-chip color filter so as to terminate at the apex of the triangular sectional shape.
