  • Patent number: 5331165
    Abstract: The present invention relates to a charge coupled device CCD X-ray imager for reducing split events during integration. The imager includes a semiconductor material having a photosensitive region for receiving X-ray radiation energy and for generating electrical charges corresponding to the received X-ray radiation, and having a plurality of permanent barriers formed therein to divide the semiconductor material into a plurality of columns. Barrier electrodes are coupled to the semiconductor material for establishing in said semiconductor material a plurality of temporary barriers having a sufficient potential gradient to substantially reduce the occurrence of split events. Collection site electrodes are coupled to the semiconductor material for effecting the collection of the generated electrical charges. The temporary barriers are erected in the columns to form an array of potential wells.
