Abstract
An alternating-current source (2) is connected to two cathodes (6,7) which cooperate electrically with targets which are sputtered in a gas discharge while a process gas is introduced in a vacuum chamber (15). A network formed of a transformer (3) and additional coils (5, 12, 13) and condensers (4, 8, 9, 10, 11) acts as a filter to assure a stable coating process.
