Claim Text:
1. A solid-state imaging device comprising: a pixel region in which a plurality of pixels are disposed in a matrix above a semiconductor substrate; and a peripheral region in which a multilayer interconnect structure for driving the plurality of pixels is formed, the peripheral region being peripheral to the pixel region in a plan view of the semiconductor substrate, wherein the pixel region includes: a charge accumulation and diffusion layer in the semiconductor substrate; a plurality of pixel plugs formed above and electrically connected to the charge accumulation and diffusion layer, the plurality of pixel plugs respectively corresponding to the plurality of pixels; a plurality of lower pixel electrodes formed on and electrically connected to the plurality of pixel plugs, respectively, the plurality of lower pixel electrodes respectively corresponding to the plurality of pixels; a photoelectric conversion film formed on and electrically connected to the plurality of lower pixel electrodes; and an upper pixel electrode formed on and electrically connected to the photoelectric conversion film, and a top surface of an interconnect formed in an uppermost layer of the multilayer interconnect structure disposed in the peripheral region is above a bottom surface of the photoelectric conversion film.
