ABSTRACT:
A meander channel charge couple device having a pair of parallel colinear elongate electrodes extending longitudinally along the length of the register disposed over a meander channel and formed in the same conductive layer so that they both reside at the same height above the semiconductor substrate, thereby providing a symmetrical surface potential distribution. Charge transfer instabilities beneath a gap separating the electrodes are eliminated by providing an additional set of electrodes, each extending transversely to the meander channel and to the first pair of parallel electrodes and spanning the gap. Contact is made by each of the longitudinal electrode pairs to alternate ones of the transverse electrodes and a two-phase clock system is applied to the longitudinal electrode pair.
