Solid-state imaging device with an electrically connected light shield layer

摘要

A solid-state imaging device. A hole accumulation layer is provided on the surface of a photosensor region. Voltage lower than the voltage of the hole accumulation layer is applied to a light-shielding film, so that positive charges existing in a thin insulation film can be attracted toward the light-shielding film. Consequently it becomes possible to reduce a dark current.
