Abstract
A backside illumination semiconductor image sensor, wherein each photodetection cell includes a semiconductor body of a first conductivity type of a first doping level delimited by an insulation wall, electron-hole pairs being capable in said body after a backside illumination; on the front surface side of said body, a ring-shaped well of the second conductivity type, this well delimiting a substantially central region having its upper portion of the first conductivity type of a second doping level greater than the first doping level; and means for controlling the transfer of charge carriers from said body to said upper portion.
