Abstract
Charge transfer devices which permit movement of charge carriers in two noncollinear directions in the surface plane of the device. A network of electrodes in two levels of metallization is combined with an appropriate doping of the storage medium to define the charge transfer paths. The direction of charge transfer is determined by an appropriate pulsing of the network which may take the form of different driving sequences of a number of phases in various embodiments. This concept may be used for both charge coupled and bucket brigade devices.
