Abstract
An imaging device includes a plurality of pixel transistors at a substrate surface of a semiconductor substrate, an element isolation region that isolates the plurality of pixel transistors from each other, a charge storage region at a deeper position in the semiconductor substrate than the substrate surface, and a charge discharge layer of the same conductivity type as the charge storage region. The charge discharge layer is arranged between the element isolation region and the charge storage region.
