Abstract
A solid-state imaging device. An intermediate portion of a channel region have a tapered width from one shift register in which the signal charges to be read-out toward the other shift register. Therefore, the potential distribution of the channel region along the charge transfer direction has a continuous down-slope toward the one shift register. Thus, reading-out electric field can be improved.
