Abstract
A solid-state imaging device having a plurality of semiconductor layers of a first conductivity type for photo-electric conversion provided on the surface of a first semiconductor layer of a second conductivity type which is formed on a part of one surface of a semiconductor substrate of the first conductivity type, a semiconductor layer of the first conductivity type for charge transfer provided on the surface of a second semiconductor layer of the second conductivity type which is formed on a part of the surface of the substrate, and a signal output means. The first semiconductor layer of the second conductivity type and the second semiconductor layer of the second conductivity type are formed in different steps so that the first semiconductor layer is disposed deeper than the second semiconductor layer.
