Abstract
A time-of-flight detection pixel includes a photosensitive area including a first doped layer and a charge collection area extending in the first doped layer. At least two charge storage areas extend from the charge collection area, each including a first well more heavily doped than the charge collection area and separated from the charge collection area by a first portion of the first doped layer which is coated with a gate. Each charge storage area is laterally delimited by two insulated conductive electrodes, extending parallel to each other and facing each other. A second heavily doped layer of opposite conductivity coats the pixel except for at each portion of the first doped layer coated with the gate.
