Patent ID: 8613828

Claim:
A device for a production of a plasma that comprises: a vacuum chamber ( 1 a ) of a vacuum recipient ( 1 ); and at least one induction coil ( 2 ) for at least co-producing the plasma in said vacuum chamber ( 1 a ); and wherein the vacuum chamber ( 1 a ) comprises: at least one inlet ( 3 ) to admit a gas serving for the production of the plasma, at least one pump arrangement ( 4 ), a substrate table ( 8 ), and a dark space screening, established as a grounded surface placed at less than a dark space distance from an electrode surface to prevent a glow discharge between the two surfaces, the induction coil ( 2 ) is connected to an alternating current and a direct current, the direct current is continuously applied during a plasma processing simultaneously with said alternating current to the induction coil ( 2 ) in order to influence a plasma density, said induction coil ( 2 ) is separated by means of a dielectric inner casing ( 7 ) or a dielectric window from at least a part of the vacuum recipient ( 1 a ) in which the plasma is produced, the alternating current is produced by a high frequency generator ( 6 ) operating at a frequency between 100 and 14,000 kHz, the substrate table ( 8 ) is provided for a substrate ( 9 ), the substrate table ( 8 ) is formed by an electrode ( 5 a ), the dark space screening is used as a counter-electrode ( 5 b ), wherein said electrode and said counter-electrode form a pair of electrodes and wherein, the plasma is co-produced or co-exited by an electric voltage applied to said pair of electrodes ( 5 a ), ( 5 b ) separated by said dark space distance.
