Abstract

A fast frame interline transfer charge coupled device imaging sensor includes an imaging section and an storage section. The imaging section includes a plurality of interline transfer registers, each interline transfer register containing a plurality of interline register elements. The imaging section further includes an interline clocking structure, the interline clocking structure including polycrystalline silicon buss lines used as gate electrodes, the polycrystalline silicon buss lines being connected to a metal strapping network, the interline clocking structure causing charge to be transferred between interline register elements of each interline transfer register based on interline clocking signals. The storage section is coupled to the imaging section. The storage section includes a plurality of storage registers, each storage register containing a plurality of storage register elements. The storage section further includes a storage discharge structure and a storage clocking structure. Each storage register element of the storage registers is selectively coupleable through the storage discharge structure to a storage drain. The storage clocking structure has first and seco…
