Method for manufacturing magnetron sputter-coated workpieces includes placing a substrate adjacent a magnetron source having a target cathode, generating above the target cathode, at least one plasma loop by an electron trap established by generating a magnetic field which forms, in top view on the target cathode, a magnet field loop and, viewed in cross-section on the target cathode, a tunnel-shaped arc field and, an electric field which crosses the magnetic field of the magnet field loop. Plasma density distribution above the target cathode is controlled by interacting a control anode with the electron trap in a control segment area of the plasma loop. Magnetron sputter-coating the substrate by the magnetron sputter-source then takes place.
