Abstract:
1. A plasma system for substrate processing, comprising: a first conducting electrode (bb) having a first side on which one or more substrates (d) can be supported and having a second side opposite the first side; a second conducting electrode (a) placed adjacent to but separated from the first conducting electrode (bb) on the second side; and a gas mixture distribution shower head (e) placed away from the first conducting electrode (bb) on the first side and within line-of-sight of at least one of the substrates, the gas mixture distribution shower head configured to supply a gas mixture (f) for processing the substrates, the first and second conducting electrodes (bb) and (a), respectively, and the shower head (e) arranged with respect to one another such that a plasma (c) is initiated and established between the first conducting electrode (bb) and the second conducting electrode, enveloping at least one of the substrates held by the first conducting electrode and is kept away from the shower head (e) activating and distributing the gas mixture through orifices (ee) in the shower head (e).
