Abstract
A back-side illuminated pixel including a semiconductor substrate of a first conductivity type coated, on the front side of the pixel, with a three-layer assembly successively including a first layer of the second conductivity type, an insulating layer, and a second semiconductor layer. The three-layer assembly is interrupted in a central portion of the pixel by a transfer region of the first conductivity type laterally delimited by an insulated conductive wall extending from the front surface, Transistors are formed in the second semiconductor layer.
