Abstract
An image sensor includes photodetection pixels formed inside and on top of a semiconductor substrate. An interconnection network coats a surface of the semiconductor substrate. The interconnection network includes a level of conductive vias in contact, by their lower surface, with the photodetection pixels. The conductive vias are made of doped polysilicon and have a heavier doping on their lower surface side than on their upper surface side.
