Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate; a plurality of photoelectric conversion elements; a plurality of vertical charge transfer paths that transfer charges generated in the plurality of photoelectric conversion elements, in a vertical direction; a horizontal charge transfer path that transfers the charges transferred in the plurality of vertical charge transfer paths, in a horizontal direction orthogonal to the vertical direction; a plurality of charge accumulating sections between the plurality of vertical charge transfer paths and the horizontal charge transfer path; a plurality of electrodes disposed above the respective charge accumulating sections, the plurality of electrodes being classified into a plurality of kinds of electrodes; wirings corresponding to the respective kinds of electrodes and extending in the horizontal direction above the plurality of electrodes; and a planarizing layer disposed between the wirings and an uneven surface caused by the plurality of electrodes that are present in areas overlapping the wirings, so as to planarize the uneven surface, wherein the planarizing layer includes a conductive material filled in gaps between the electrodes, and an insulating material formed around the electrodes and the conductive material.
