Abstract:
1. A vacuum arc vapor deposition process, comprising the steps of: being evaporated a cathode material from an evaporating source by arc discharge, the cathode material being located at one end of a curved or bent duct; forming a magnetic filter by disposing a plurality of magnets at a plurality of locations along and around said duct, said plurality of magnets including a terminal magnet, said terminal magnet being located closest to a plasma injection hole, which is located at the other end of said duct wherein a mounting angle of said terminal magnet is variable; generating a deflection magnetic field within said duct by said magnetic filter; transporting a stream of plasma including ions of said cathode material from one end of said duct to said plasma injection hole while removing droplets generated by said evaporation of said cathode material; inclining said terminal magnet to a plasma injection plane of said plasma injection hole so that traveling directions of said ions of the stream of plasma are controlled by a magnetic field, said magnetic field being generated by said terminal magnet; and extracting said controlled ions of said plasma stream from said plasma injection hole into a film forming chamber so that said controlled ions of said plasma stream deposits onto a substrate in said film forming chamber.
