Abstract

Disclosed is an apparatus for plasma-enhanced processing of substrates, hng a recipient in which ions and reactive neutral particles (radicals) formed in plasma act on the substrate. The present invention is distinguished by having means for varying the plasma volume are provided in order to control the absolute values of the ionic current densities and the radical current densities and in order to control the relative ratio of the ionic current densities and the radical current densities on the surface of the substrate.
