Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate provided with an effective pixel region and an optical black region, the effective pixel region including light receiving sections that photoelectrically convert incident light and the optical black region being located at a periphery of the effective pixel region and being optically shielded, the semiconductor substrate having a light receiving face; an interconnection layer that is provided on a side of the semiconductor substrate that corresponds to a face of the semiconductor substrate opposite to the light receiving face; a first groove portion that is provided between adjacent light receiving sections and is formed at a predetermined depth in the semiconductor substrate from the light receiving face; a second groove portion that is provided between the optical black region and the effective pixel region and is formed at a predetermined depth in the semiconductor substrate from the light receiving face; an insulating material that is embedded in at least a part of the first groove portion; and a high-dielectric material film formed between the first groove portion and the insulating material.
