Abstract
In a region of a weak internal electric field, photocharges generated in a region deeper than the photodiode are diffused laterally to lower the sensitivity by photoelectrons flowing into adjacent pixels, etc (crosstalk). An anti-crosstalk layer is disposed in the photodiode forming portion, and between a pixel region and a peripheral circuit region. Crosstalk between a pixel and a pixel or between a pixel region and a peripheral circuit region is decreased to improve the photosensitivity.
