Patent ID: 8810699

Claim:
A solid state imaging device, comprising: a semiconductor substrate; a light receiving region provided on a surface layer on a first surface side of said semiconductor substrate, the light receiving region including a silicided surface; a second impurity diffusion layer provided adjacent to said light receiving region on said surface layer on said first surface side of said semiconductor substrate; a gate insulating film provided adjacent to said second impurity diffusion layer on said first surface of said semiconductor substrate; a gate electrode provided on said gate insulating film; and a third impurity diffusion layer provided on an opposite side to said second impurity diffusion layer, with said gate insulating film and said gate electrode sandwiched, wherein said light receiving region comprises a first impurity diffusion layer which forms a PN junction with neighboring said semiconductor substrate, wherein said first impurity diffusion layer has a same conductivity-type with the second impurity diffusion layer, wherein said second impurity diffusion layer, said gate insulating film, said gate electrode, and said third impurity diffusion layer constitute a field-effect transistor, and wherein light from an object to be imaged incident on a second surface of said semiconductor substrate is photoelectric-converted inside said semiconductor substrate, said light receiving region receives electric charge generated by said photoelectric conversion, and said object to be imaged is imaged.
