Abstract

A cathode sputtering apparatus for the coating of substrates in a vacuum chamber is presented which accommodates a rotating substrate carrier, and which comprises at least one gripper which includes a hub and at least one arm with a gripper with the hub rotating around a horizontal axis; during the sputtering, two annular closing elements separate a segment in front of the station from the remaining portion of the vacuum chamber and a cathode vacuum chamber is thus formed which is separate from the vacuum chamber of the apparatus.
