A CCD shift register includes a continuous buried channel over a length of the shift register, a plurality of conductor segments, a plurality of narrow bus segments, and a plurality of wide busses. Each conductor segment includes a plurality of sets of conductors, and each set of conductors includes plurality of conductors, each conductor in a set corresponding to a respective clock signal of a plurality of clock signals. Each conductor of each set extends across the buried channel. A first narrow bus segment of the plurality of narrow bus segments includes a plurality of narrow busses that are disposed parallel to and offset from the buried channel, each narrow bus corresponding to a respective clock signal of the plurality of clock signals, and each narrow bus is coupled to a respective conductor of each set of a first conductor segment. Each wide bus corresponds to a respective signal of the plurality of clock signals, and each wide bus is coupled to a respective narrow bus of the first narrow bus segment, each wide bus being more conductive than any narrow bus.
