Classification: CPC H | IPC H

Claim 9:
10. An electronic apparatus comprising
a solid-state imaging device that is mounted in the electronic apparatus, wherein
the solid-state imaging device includes:
a photoelectric conversion unit that converts received light into an electric charge;
a memory unit that holds the electric charge transferred from the photoelectric conversion unit; 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 a back surface side of the semiconductor substrate, and is continuously formed to include a first embedded portion and a second embedded portion that are embedded between the photoelectric conversion unit and the memory unit and extend in the semiconductor substrate, the back surface side of the semiconductor substrate being a side at which light to the memory unit enters,
the first embedded portion is disposed in a transfer region to transfer the electric charge from the photoelectric conversion unit to the memory unit, and the second embedded portion is disposed outside the transfer region, and
the lid portion of the light blocking unit formed on the back surface side of the semiconductor substrate includes at least one recessed structure, the back surface side of the semiconductor substrate being the side at which light to the memory unit enters.
