Claim 0:
1. A method for removing portions of a thin film of an electric insulator from a surface of an underlying substrate and roughening the underlying substrate, the method comprising the steps of:
(a) placing a substrate, coated with a thin film comprising an electric insulator on at least one of the substrate's surfaces, in between two electrodes that are each electrically connected to a plasma generator; and
(b) activating the plasma generator to discharge a plasma-containing electron beam or arc upon the thin film, thereby removing portions of the thin film from the entrance side and roughening the underlying substrate by the beam or arc;
provided that no liquid solution is used on the thin film before or during the above two steps.
