Abstract : This invention relates to charge-coupled devices (CCD) and especially to two-phase, charge-coupled, metal-oxide semiconductor (MOS) devices with overlapping polysilicon gates. Two-phase CCD's in the form of polysilicon overlapped by aluminum have proved to be viable structures capable of high yield and excellent operation in devices such as analog computers where they can be used as shift registers, for example. The long gate electrodes of one phase are connected at both ends to a pair of bus lines carrying its clock signal and the long gate electrodes of the second phase are connected at both ends to another pair of bus lines carrying the other clock signal. An object of this invention is to minimize the relative delay of clock pulses between two long adjacent gate electrodes in a two-phase, charge-coupled device. Another object is to admit more light through a two-phase, charge-coupled device for TV systems.
