Abstract
A vacuum chamber includes a central compartment (1) in which a diode cathode (6) carrying an electrically conductive sputtering target (7) is located, and two outer compartments (11, 12) in which magnetron cathodes (13, 14) carrying target 15, 16) are located, the magnetron cathodes (13, 14) being connected to respective poles (20, 21) of an AC power source. The outer compartments (11, 12) are separated from the central compartment by walls having openings (33, 34) which flank a space (28) between the sputtering target (6) and the substrate (3). Process gas lines 24, 25) are arranged to introduce process gas into this space (3).
