Abstract
Disclosed herein is a solid-state image pickup device of a type wherein a pixel is configured to include a sensor unit capable of photoelectric conversion, the image pickup device including: a semiconductor substrate; a charge storage region of a first conduction type, which is formed in the semiconductor substrate and constitutes a sensor unit; a charge storage sub-region made of an impurity region of the first conduction type, which is formed, in plural layers, in the semiconductor substrate below the charge storage region serving as a main charge storage region and wherein at least one or more of the plural layers are formed entirely across a pixel; and a device isolation region that is formed in the semiconductor substrate, isolates pixels from one another, and is made of an impurity region of a second conduction type.
