CCD image sensors (referred to simply as CCD from now on) are semiconductor devices invented by Willard Boyle and George Smith at the AT&T Bell Laboratories in 1970. CCDs are image sensors grouped within a family of charge transfer devices (CTD) that transfer charges through the semiconductor by using potential wells. Most current CCDs have a buried channel CCD (BCCD) structure in which the charge transfer channels are embedded inside the substrate.
