Abstract
According to one embodiment, a solid-state imaging device includes a semiconductor substrate of a first conductive type having a diffusion layer region provided on a surface thereof, a diffusion layer of the first conductive type for a pixel separation whose bottom portion is formed at the deepest position of the diffusion layer region in a pixel region, and a first deep diffusion layer of the first conductive type provided at the deepest position of the diffusion layer region in a first peripheral logic region for electrically connecting the semiconductor substrate and the first peripheral logic region and having a first concentration gradient equal to that of the diffusion layer for pixel separation.
