Abstract
A solid-state imaging device includes an array of photosensitive cells, each of which includes a photoelectric conversion section, which is arranged on the surface of a substrate and has a light-receiving opening. The photoelectric conversion section generates a packet of electrical carriers in response to the amount of incident light thereinto through the opening. A charge transfer section is arranged adjacent to the photoelectric conversion section on the substrate surface. This transfer section defines thereunder a transfer channel region that extends linearly in a predetermined direction in the substrate surface, and causes the carriers thus obtained to move sequentially. A light-shield section is arranged to cover the photoelectric conversion section except the opening, for preventing an incident light coming through the opening from being introduced into the transfer channel region as a leak component, by cutting off an internal reflection path of the leak component thereto.
