Patent ID: 8786739

Claim:
A photoelectric conversion device comprising: a semiconductor substrate in which photoelectric conversion units including first photoelectric conversion units and second photoelectric conversion units are arrayed in a direction along a row and a direction along a column; a multilayer wiring structure arranged on the semiconductor substrate and including an uppermost wiring layer; first color filters, each of the first color filters is arranged above a corresponding one of the first photoelectric conversion units; second color filters, each of the second color filters is arranged above a corresponding one of the second photoelectric conversion units; and an insulation film arranged to cover the uppermost wiring layer, wherein the first color filters and the second color filters are arranged on the insulation film, the first color filters are arranged two-dimensionally to form a pattern having openings at regions above the second photoelectric conversion units, the second color filters are arranged in the openings of the pattern to fill the openings such that an edge portion of each second color filter overlaps and is in contact with an edge portion of the first color filter adjacent to that second color filter in either of the direction along the row and the direction along the column, the first color filters adjacent to each other in a diagonal direction share their corner portions, and corner portions of the second color filters are arranged on the shared corner portions of the first color filters, wherein the insulation film is formed from an inorganic material, and the first color filters and the second color filters are formed from an organic material, wherein the insulation film has convex portions and concave portions suited to the uppermost wiring layer, the first color filters and the second color filters overlap with each other on the convex portions of the insulation film, and portions where the edge portion of each first color filter and the edge portion of each second color filter overlap with each other have a width which is not less than ½ of a width of one of the convex portions and not greater than the width of one of the convex portions.
