Abstract
A back-illuminated integrated imaging device is formed from a semiconductor substrate including a zone of pixels bounded by capacitive deep trench isolations. A peripheral zone is located outside the zone of pixels. A continuous electrically conductive layer forms, in the zone of pixels, an electrode in a trench for each capacitive deep trench isolation, and forms, in the peripheral zone, a redistribution layer for electrically coupling the electrode to a biasing contact pad. The electrode is located in the trench between a trench dielectric and at least one material for filling the trench.
