  • Method of electrochemically processing a substrate and integrated circuit device
    Patent number: 11538689
    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.
    Type: Grant

    Date of Patent: December 27, 2022
    Assignee: UNIVERSITE CATHOLIQUE DE LOUVAIN
    Inventors: Gilles Scheen, Jean-Pierre Raskin, Jonathan Rasson
