Abstract
A pixel is formed on a semiconductor substrate that includes a photosensitive area having a first doped layer and a charge collection area of a first conductivity type extending through at least part of the first doped layer. At least two charge storage areas, each including a well of the first conductivity type, are separated from the charge collection area at least by a first portion of the first layer. The first portion is covered by a first gate. Each charge storage area is laterally delimited by two insulated conductive electrodes. A second doped layer of the second conductivity type covers the charge collection area and the charge storage areas.
