ABSTRACT:
A multiple electrode plasma reactor power splitter and delivery system to provide balanced power to a plurality of powered electrodes by utilizing the properties of quarter wave length transmission lines. Each electrode is supplied power by a separate (2N+1).lambda./4 wavelength cable, where N=0,1,2 . . . , connected to a common point at a load matching network's output. The impedance transformation properties of these lines are also employed to convert the plasma load to one that is more efficiently matched into by a standard network. Also disclosed is a technique of splitting a single large active electrode into smaller active electrodes powered by the above distribution scheme in order to achieve maximum uniformity of the reactive plasma throughout the working volume.
