Abstract:
1. A solid-state imaging device comprising: a plurality of photoelectric conversion portions arranged in a matrix on a substrate; a vertical transfer channel arranged between vertical columns of the photoelectric conversion portions; a plurality of vertical transfer electrodes for transferring a charge of the photoelectric conversion portions to the vertical transfer channel; a light-shielding film, laminated on the vertical transfer electrodes via a first insulating film, is divided by a slit portion formed in the region overlapping the vertical transfer channel with respect to each of the vertical columns of the photoelectric conversion portions, and has a plurality of window portions, each defining a light-receiving portion of each of the photoelectric conversion portions; a stopper layer lamented on the vertical transfer electrodes corresponding to a bottom of the slit portion; a shunt wiring that is arranged in a region overlapping the vertical transfer channel and is insulated from the light-shielding film by a second insulating film; a connection opening formed in the stopper layer in the slit portion of the light-shielding film and the second insulating film; a side wall member, formed separately from the second insulating film, and formed on the side face of the connection opening and the side surface of the slit portion in the light-shielding film in its long side direction; and a leg portion is formed continuously in a direction in which the shunt wiring is arranged and enters the slit portion, wherein a driving pulse according to a drive phase of each of the vertical transfer electrodes is supplied from the shunt wiring.
