Abstract
Apparatus for the coating and etching of substrates in a vacuum chamber (4), includes a cathode (17, 17') having a target (18, 18'), and a rotatable structure (8) shaped as an essentially cylindrical hollow body having circular disk-shaped end faces provided with pivot shafts (10, 10') held for rotation about a horizontal axis (r) in bearings (11, 11') disposed on the side walls (12, 12') of the vacuum chamber (4). Mountings (19, 19') for holding the substrates in place are provided on the circumference of the hollow body, the cathode (17, 17') and the etching anode (16) being disposed opposite the rotatable structure (8) in a plane (E) running horizontally and approximately in the plane of the axis of rotation (r).
