Patent ID: 8334552

Claim:
A solid-state imaging device having a light sensing section that performs photoelectric conversion of incident light, and a peripheral circuit section, comprising: a hole accumulation layer on a light receiving surface of the light sensing section; a first layer formed over the hole accumulation layer and formed of a material selected from the group consisting of hafnium oxide (HfO 2 ), aluminum oxide (Al 2 O 3 ), zirconium oxide (ZrO 2 ), tantalum oxide (Ta 2 O 5 ), titanium oxide (TiO 2 ), lanthanum oxide (La 2 O 3 ), praseodymium oxide (Pr 2 O 3 ), cerium oxide (CeO 2 ), neodymium oxide (Nd 2 O 3 ), promethium oxide (Pm 2 O 3 ), samarium oxide (Sm 2 O 3 ), europium oxide (Eu 2 O 3 ), gadolinium oxide (Gd 2 O 3 ), terbium oxide (Tb 2 O 3 ), dysprosium oxide (Dy 2 O 3 ), holmium oxide (Ho 2 O 3 ), erbium oxide (Er 2 O 3 ), thulium oxide (Tm 2 O 3 ), ytterbium oxide (Yb 2 O 3 ), lutetium oxide (Lu 2 O 3 ), yttrium oxide (Y 2 O 3 ), hafnium nitride, aluminum nitride, hafnium oxide nitride, and aluminum oxide nitride; and a second layer having a light-shielding function, the second layer being in contact with the first layer throughout the peripheral circuit section.
