Patent ID: 8106472

Claim:
Pixels for use in an image sensor including a two dimensional array of the pixels for detecting light from a scene, each of the pixels comprising: an active area in a substrate for converting incident radiation into photo-generated charge carriers, charge-storage areas, comprising at least a first charge-storage area and a second charge-storage area, for storing the photo-generated charge carriers, said charge-storage areas being located laterally adjacent to said active area, photogates located in said active area for generating a lateral drift field in the active area to transport the photo-generated charge carriers toward the charge-storage areas, wherein the lateral drift field is periodically modulated synchronously with modulation radiation illuminating the scene to transport the photo-generated charge carriers alternately to the first charge-storage area and the second charge-storage area; and a buried channel is provided in said active area below said photogates for increasing a depletion zone below the photogates.
