Abstract
A charge-coupled device including a semiconductor substrate of given conductivity type, a buried channel formed on the substrate of different conductivity type than the substrate, an electrically floating diffusion formed in the substrate of different conductivity type than the substrate, and a plurality of electrodes insulating from the buried channel. The electrodes are responsive to applied voltages for supplying a signal charge through the buried channel to the floating diffusion. The charged-coupled device also includes a transistor responsive to a pulse voltage signal for periodically resetting the floating diffusion to a predetermined potential. The transistor comprises an enhancement type surface channel field effect transistor.
