Abstract (en)

[origin: EP2020672A2] The device has a coupling coil (5) that supplies high frequency energy for performing plasma excitation. A coupling capacitor (22) is electrically coupled with the coil. A high frequency generator (16) i.e. radio frequency generator, is electrically coupled with the coil. The generator with the capacitor forms a resonant circuit e.g. series resonant circuit. The generator has a phase locked loop control device that automatically performs impedance matching of the circuit, so that the circuit is operated by using resonance frequency.
