Abstract
A charge transfer device is provided, capable of preventing degradation of the charge transfer efficiency when the channel width becomes narrower due to the narrow channel effect. The charge transfer device of the present invention is obtained by forming a charge transfer electric field in a channel below a boundary portion between a terminal storage electrode and a terminal barrier electrode, which constitute a pair of charge transfer electrodes located closest to the output electrode, to be higher than a charge transfer electric field in a channel below a boundary portions of pairs of storage electrodes and barrier electrodes, which constitute pairs of storage electrodes and barrier electrodes other than the pair of the terminal electrodes.
