Abstract : A pseudo uniphase CCD array having four functional regions,a clocked barrier region, a clocked well region, a virtual barrier region, and a gate variable potential well region per stage. The described structure allows flexibility in setting operating voltages and avoids the breakdown and fabrication difficulties of a virtual well region. The device employs a virtual barrier plus adjacent MOS well fixed potential region and uses clocking of barrier and well regions to achieve charge transfer. A fabrication sequence and operating potential selection criteria are also included.
