Patent ID: 8115154

Claim:
A solid-state imaging device comprising: a semiconductor substrate including a pixel portion having a photoelectric conversion portion configured to photoelectrically convert incident light to obtain an electrical signal and a peripheral circuit portion disposed at the periphery of the pixel portion; a first sidewall composed of a sidewall film and disposed on each sidewall of gate electrodes of MOS transistors in the pixel portion; a second sidewall composed of the same film as the sidewall film and disposed on each sidewall of gate electrodes of MOS transistors in the peripheral circuit portion; a first silicide blocking film composed of the same film as the sidewall film and disposed on the photoelectric conversion portion and a part of the MOS transistors in the pixel portion; and a second silicide blocking film disposed on the MOS transistors in the pixel portion so as to overlap with a part of the first silicide blocking film, wherein the MOS transistors in the pixel portion are covered with the first silicide blocking film and the second silicide blocking film.
