The novel JFET bucket-brigade structure disclosed eliminates the need for the MOS overlap capacitance of a conventional JFET brigade, and thereby greatly reduces the total storage capacitance. In comparison with conventional prior art JFET BBDL structures the novel device herein disclosed provides larger contact areas for gate electrodes, it eliminates the prior need for close spacing between clock electrodes, and the need for thin oxides. The disclosed device is a less complex structure than the prior art and thus provides a higher yield during manufacturing. Typical eighty stage embodiments provide measured transfer efficiencies at 50 MHz that are approximately a factor of five times better than that previously measured for a 10-stage conventional prior art JFET bucket brigade.
