A conductively connected charge coupled device
R.H. Krambeck, R.J. Strain, GW Smith, K.A. Pickar · 1972
From the viewpoint of the fabricator and user, a charge coupled device should be two-phase, have no requirement for narrow metal gaps, use only a single type of insulated gate structure, require little change in standard IGFET processing, and offer the same reliability that other circuits have. The Conductively Connected Charge Coupled Device (C4D) satisfies these requests.
