Abstract
Disclosed is a charge-transfer or charge-coupled (CCD) type device, aimed at increasing the charge storage capacity. The disclosed photosensitive device includes a plurality of photosensitive cells. Each photosensitive cell includes an elementary photosensitive zone beneath which there is formed a potential well. According to one characteristic, the potential well has a surface area greater than the surface area of the elementary photosensitive zone. The disclosure can be applied to charge-couped devices that include a non-photosensitive zone between the pixels.
