ABSTRACT:
A charge coupled device has a plurality of N-diffused regions and a plurality of N.sup.- diffused regions arranged alternately along a charge transfer channel. A first electrode and second electrode overlying each N-diffused region and N.sup.- -diffused region form a pair of electrodes, four of which form a group of electrodes iteratively appearing along the charge transfer channel. Each first pair and each third pair are connected to a first signal line and second signal line, respectively, which receive two-phase driving clock signals, while each second pair and fourth pair are connected to a fixed potential line maintained at a middle potential between the high level and low level of the driving signals. A high-speed transfer of signal charges is obtained in the two-phase type charge coupled device.
