Abstract
A photosite may include, in a semi-conductor substrate, a photodiode pinched in the direction of the depth of the substrate including a charge storage zone, and a charge transfer transistor to transfer the stored charge. The charge storage zone may include a pinching in a first direction passing through the charge transfer transistor defining a constriction zone adjacent to the charge transfer transistor.
