A plasma system for substrate processing comprising, a conducting electrode (b, bb) on which one or more substrates (d) can be held; a second conducting electrode (a) placed adjacent but separated from the substrate holding electrode on the side away from the side where the substrates are held; and a gas mixture distribution shower head (e) placed away from the conducting electrode on the side where the substrates are held for supplying the gas mixture (f) needed for processing the substrates in a uniform manner; such that a plasma configuration initiated and established, between the conducting electrode holding the substrates and the second conducting electrode envelops the electrode holding the substrate, is kept away from the shower head activating and distributing the gas mixture through orifices (ee) in the shower head, thereby providing the advantages of improved uniformity, yield and reliability of the process. |
