Abstract-The Tacking CCD is a new type of charge transport mechanism that is suitable for junction-as well as MOStype CCD's. A specific form, the Trenched Tacking CCD (TTCCD), promises high pixel density and high charge handling capability per unit of surface area. The TTCCD structure is suitable for making new types of solid-state image sensors with increased light sensitivity and there is the possibility of incorporating a vertical overflow drain. First samples of the TTCCD have been realized and its functionality has been confirmed.
