Abstract (en)

[origin: WO03030207A1] The invention relates to a method for producing a plasma. Said plasma is produced in the vacuum chamber (la) of a vacuum recipient (1) of a device which is suitable for plasma treatment, by means of at least one induction coil (2) which is acted upon by an alternating current. The gas used to produce the plasma is introduced into the vacuum chamber (la) via at least one inlet (3), and the vacuum chamber (la) is pumped by means of at least one pumping unit (4). In order to influence the density of the plasma, the induction coil (2) is additionally acted upon by an optionally pulsed direct current.
