  • Publication number: 20090044754
    Abstract: A device is disclosed for supporting a plasma-enhanced coating process. The device is disposed in the vicinity of a plasma and/or a substrate to be coated and/or an electrode provided for plasma generation. The device at least partially surrounds or limits a side or a plane of the plasma area or a plane in which the substrate or a carrying element carrying the substrate can be arranged, or of one of the electrodes or parts. The device comprises a cavity or a suction channel with one or several suction openings through which a gaseous medium can be suctioned off.
