ABSTRACT:
A solid-state color imaging device comprises a semiconductor substrate having a plurality of optoelectrical conversion regions on a major surface of the substrate and an insulating layer on the major surface of the substrate. On the insulating layer is a light shielding layer having an array of holes respectively aligned with the optoelectrical conversion regions. On the light shielding layer is an anti-reflection layer to absorb light reflected from the light shielding layer. A color anti-blending layer and a color dyeing layer are successively formed on the anti-reflection layer. The color dyeing layer has an array of color filtering regions in positions which correspond respectively to the optoelectrical conversion regions.
