Abstract

A substrate has a front side including an electrical circuit and a rear side including an exposed zone that faces the electrical circuit. In an electrochemical treatment step, an electrical potential is laterally applied at least to the exposed zone of the rear side of the substrate, while the exposed zone is in contact with a chemically reactive substance. The electrical potential causes a lateral flow of electrical current at least in the exposed zone of the substrate. The lateral flow of current and the chemically reactive substance alter the substrate in at least the exposed zone.
