Abstract:
A method of establishing a DC bias in front of at least one electrode in a plasma operating apparatus by applying an RF voltage with at least two harmonic frequency components with a controlled relative phase between the components, where at least one of the higher frequency components is established as an even multiple of the lower frequency component.
