Patent ID: 7554069

Claim:
A solid state imaging device having an image area in which a plurality of light receiving pixels is arranged on a semiconductor substrate of a first conductive type, the solid state imaging device comprising: a plurality of photosensor parts formed by providing on the semiconductor substrate a light receiving area and a photoelectric conversion area both configuring the light receiving pixel; a first well region formed on the opposite side of the light receiving area with the photoelectric conversion area of the photosensor parts being interposed therebetween, having a second conductive type opposite to the first conductive type, and forming an overflow barrier; a second well region of the second conductive type formed in an area except a place corresponding to the photosensor parts on the opposite side of the photoelectric conversion area with the first well region being interposed therebetween; and a first conductive region formed in an area corresponding to the photosensor parts on the opposite side of the photoelectric conversion area with the first well region being interposed therebetween.
