ABSTRACT:
A uniphase charge transfer device comprises a plurality of electrode pairs disposed over a layer of gate oxide which overlies a semiconductor substrate. Within the substrate are a plurality of first conduction regions which are doped to a conductivity type opposite to that of the substrate. The first conduction regions underlie the separations between electrode pairs, and each one is electrically connected to one member of each electrode pair. A plurality of second conduction regions in the substrate are of the same conductivity type as the substrate but are of a substantially greater density of impurity atoms, and each of the second conduction regions underlies a portion of the other member of each electrode pair. A single clock line is connected to that member of each electrode pair which overlies the second conduction region. By alternatingly applying a predetermined voltage to the single clock line, charge packets representing information are moved unidirectionally through the device.
