ABSTRACT:
A CCD sensor structure adapted for backside illumination, has a wide depletion layer separating the illuminated surface from potential barrier-like structures, e.g., in the form of a series of p-wells, that shield portions of the CCD channels and that cause the photoelectrons to converge through "ports" between the p-wells into selected regions of the CCD channels. The potential barriers are thus arrayed to delineate at the CCD surface a series of charge-packet-forming or integrating regions, each of which has two (or more) adjacent shielded charge-packet-holding or storage regions into which the frame-indicative charge packets are successively shifted upon receipt of the light from successive image frames. With an anti-reflective coating on the illuminated back surface, this device not only provides 100% fill-factor for each of the successive frames, but also can provide very high quantum efficiency (QE) across the visible spectrum. A preferred embodiment utilizes 7-phase (non-barrier-type) ripple clocking for charge packet readout.
