Abstract:
A solid-state imaging device comprising:a photoelectric conversion section formed on a substrate; a charge transfer section formed adjacent to said photoelectric conversion section said charge transfer section receives and transfers a signal charge generated by said photoelectric conversion section; a read-out section formed on said substrate, said read-out section reads said signal charge generated by said photoelectric conversion section to said charge transfer section; a gate oxide film formed over said read-out section and said charge transfer section; a plurality of charge transfer electrodes formed on said gate oxide film, and having spaces formed therebetween; a first insulation film overlying said gate oxide film and filling said spaces between said plurality of charge transfer electrodes; a second insulation film overlying said first insulation film and said plurality of charge transfer electrodes, said second insulation film having a flat top surface; and a metal film overlying said second insulation film.
