Claim Text:
1. An apparatus for sputtering comprising: at least one magnetron including: a coating chamber including a substrate holder for holding a substrate to be coated by the apparatus; a plasma duct having (a) an entrance disposed along the working axis and (b) an exit disposed off of the working axis, such that the coating chamber is in communication with the at least one rectangular cathode plate through the exit, the plasma duct, and the entrance; at least one anode spaced from the sputtering surface and disposed between the sputtering surface and the entrance, the at least one anode being connected to a positive pole of another current source; at least one cathode-ionizer, disposed outside the exit and connected to a negative pole of the another current source, for generating an arc-discharge through the plasma duct between the at least one cathode-ionizer and the at least one anode so as to ionize the vapor to create a magnetron vapor plasma; and a plurality of deflecting conductors arranged around the plasma duct and defining a curvilinear path, for deflecting flow of the magnetron vapor plasma through the plasma duct, off of the working axis, and through the exit toward the coating chamber.
