Abstract:
1. A solid-state imaging device comprising: a substrate with a photoelectric conversion region, the photoelectric conversion region comprising (a) a photoelectric conversion portion in the substrate that generates electric charge in response to light irradiated thereon, and (b) a charge accumulated portion positioned adjacent the surface of the substrate and between the surface of the substrate and the photoelectric conversion portion; a well region spaced from the photoelectric conversion region; a read gate between the well region and the photoelectric conversion region; a transfer channel adjacent the surface of the substrate and positioned between the surface of the substrate and the well region; a charge transfer electrode positioned to effect transfer of charges out from the well region; a light-shielding film positioned over said charge transfer electrode; and a voltage applying portion separate from said charge transfer electrode and from said light-shielding film, the light-shielding film positioned over said voltage-applying portion, wherein,
