Abstract
A solid-state imaging device, includes: a substrate where a region of a first conductivity type is formed on at least a portion of a surface thereof; a region of a second conductivity type formed on at least a portion of a surface of the region of the first conductivity type; a multilayer wiring layer formed on the substrate; and a layer of the second conductivity type formed directly above the region of the second conductivity type in the multilayer wiring layer, connected to the region of the second conductivity type. A concentration of impurities in the layer of the second conductivity type is lower with decreasing proximity to the region of the second conductivity type.
