Abstract
A charge transfer device in which a number of transfer electrodes, comprised of alternating main electrodes and auxiliary electrodes, are formed on but insulated from a channel region in a semiconductor substrate for transferring charges. The transfer electrodes are formed such that the sides of each of the electrodes which are transverse to the channel direction are concave in the direction of charge transfer. These concave sides produce an additional accelerating electric field which supplements the conventional fringing fields.
