Patent ID: 7733398

Claim:
A photoelectric converting film stack type solid-state image pickup device comprising: a semiconductor substrate; at least one photoelectric converting film that generates signal charges corresponding to an amount of incident light, said at least one photoelectric converting film being above the semiconductor substrate, and wherein said at least one photoelectric converting film comprises: a red-detection photoelectric converting film; a green-detection photoelectric converting film; and a blue detection photoelectric converting film, the blue detection photoelectric converting film is above the green-detection photoelectric converting film, the green-detection photoelectric converting film is above the red-detection photoelectric converting film; at least one set of pixel electrode films arranged in row and column directions of said at least one photoelectric converting film and attached to said at least one photoelectric converting film; a plurality of vertical transfer paths in a surface portion of the semiconductor substrate, extended in the column direction; and a plurality of charge accumulating portions that accumulate signal charges from the pixel electrode films, said plurality of charge accumulating portions being in the surface portion of the semiconductor substrate, wherein said plurality of charge accumulating portions comprise a plurality of subsets, each subset comprising at least two of the charge accumulating portions arranged in the column direction, and wherein the subset of the charge accumulating portions reads out the accumulated signal charges to the corresponding one of the vertical transfer paths, and wherein the two adjacent subsets of the charge accumulating portions are shifted to each other in a direction along the vertical transfer paths, wherein a first arrangement pitch of the pixel electrode films in the row direction is equal to a second arrangement pitch of the pixel electrode films in the column direction, wherein said at least one set of pixel electrode films comprises: a first set of pixel electrode films for red which is attached to the red-detection photoelectric converting film; a second set of pixel electrode films for green which is attached to the green-detection photoelectric converting film; and a third set of pixel electrode films for blue which is attached to the blue-detection photoelectric converting film, wherein the first set of pixel electrode films, the second set of pixel electrode films and the third set of pixel electrode films are shifted from each other in the row direction by ⅓ of an arrangement pitch of the pixel electrode films, and wherein a first accumulating portion included in one of the subsets of the plurality of charge accumulating portions is apart from a second accumulating portion adjacent to the first accumulating portion included in the same subset by one arrangement pitch of the pixel electrode films in the column in direction.
