Abstract
Provided is a solid-state imaging device including: a photoelectric conversion unit that converts received light into an electric charge; a memory unit that holds the electric charge; and a light blocking unit that blocks light. The photoelectric conversion unit and the memory unit are formed in a semiconductor substrate. The light blocking unit is formed as a lid portion on the back surface side of the semiconductor substrate, which is the side at which light to the memory unit enters, and is also continuously formed including a first embedded portion and a second embedded portion that are embedded between the photoelectric conversion unit and the memory unit so as to extend in the semiconductor substrate. The first embedded portion is in a transfer region for transferring the electric charge, and the second embedded portion is outside the transfer region. The lid portion includes at least one recessed structure.
