ABSTRACT:
A system for removing a thin metal film is disclosed. The system comprises an inclined metal plate electrode for guiding a downward electrolyte flow, an auxiliary electrode placed on either the upstream or downstream side of the metal plate electrode such that a part of the auxiliary electrode is immersed into the electrolyte, and a power supply for applying a DC voltage to the both electrodes. The system is used to remove a metal thin film on the surface of an insulator by making the electrolyte flowing down the metal plate electrode strike against the metal thin film while the DC voltage is applied to the metal plate electrode and auxiliary electrode.
