Patent ID: 8410418

Claim:
A solid-state imaging device comprising a light-receiving portion operative to photoelectrically convert incident light includes: a first film over a light-receiving surface of the light-receiving portion, the first film formed by a material selected from the group consisting of a hafnium oxide, aluminum oxide, zirconium oxide, tantalum oxide, titanium oxide, lanthanum oxide, praseodymium oxide, cerium oxide, neodymium oxide, promethium oxide, samarium oxide, europium oxide, gadolinium oxide, terbium oxide, dysprosium oxide, holmium oxide, erbium oxide, thulium oxide, ytterbium oxide, lutetium oxide, yttrium oxide, hafnium nitride, aluminum nitride, hafnium oxide nitride, and aluminum oxide nitride; a second film of approximately 1 nm thickness between the light-receiving surface and the first film; and a hole accumulation layer at the light-receiving surface side of the light-receiving portion, the hole accumulation layer created due to the existence of the first film.
