    Abstract: A method for producing at least one deep trench isolation in a semiconductor substrate including silicon and having a front side may include forming at least one cavity in the semiconductor substrate from the front side. The method may include conformally depositing dopant atoms on walls of the cavity, and forming, in the vicinity of the walls of the cavity, a silicon region doped with the dopant atoms. The method may further include filling the cavity with a filler material to form the at least one deep trench isolation.
