Solid-state imaging device and electronic device

摘要

A solid-state imaging device is provided. The solid-state imaging device includes an imaging area including a plurality of pixels arrayed in a two-dimensional matrix. Each of the pixels includes a photodiode having a first conductivity-type electric charge accumulation area and a transistor for reading electric charges obtained at the photodiode; and an independent first conductivity-type region provided to at least part of the plurality of pixels and isolated from the photodiode and the transistor. The independent first conductivity-type region is provided continuously between adjacent pixels and nonuniformly within each pixel.
