Abstract:
According to the method, a voltage which maintains the plasma is produced by superimposing on a radio-frequency voltage at a defined operating frequency at least one further radio-frequency voltage, in each case at a multiple of this operating frequency, and in each case with a variable amplitude and phase, on a phase-locked basis. At least two radio-frequency power generators (1 to 4) are provided for a corresponding generator circuit, one (1) of which operates at a defined operating frequency (f) and the other or others of which (2 to 4) each operate at a multiple of this operating frequency (f). All the radio-frequency power generators (1 to 4) are coupled to one another on a phase-locked basis, and the relative phase angle as well as the respective amplitude of each radio-frequency power generator (1 to 4) can be regulated individually by means of a dedicated matching circuit (5 to 8). As an alternative to this, it is possible to provide an oscillator which operates at a defined operating frequency (f) and at least one further frequency multiplier, which is connected downstream from the oscillator, said frequency multiplier or multipliers producing harmonics of this operating frequency (f).
