Abstract:
An apparatus for plasma processing, having a plurality of processing chambers in which plasma is generatable, said apparatus comprising:a plurality of first belt-like electrodes provided on the outer periphery of each of said processing chambers; and a plurality of second belt-like electrodes provided on the outer periphery of each of said processing chambers, said first belt-like electrodes and each of said second belt-like electrodes being provided alternately and being separated vertically with respect to each other on each of said processing chambers; wherein: said first belt-like electrodes are adapted to be connected to a high-frequency electric power source, while said second belt-like electrodes are adapted to be connected either to the earth or to an electric power source lower in frequency than that of said high-frequency electric power source; said first belt-like electrodes on each said processing chamber having a first portion adapted to be connected to the high frequency power source, and a second portion electrically connected to said first belt-like electrodes on another said processing chamber; and said first belt-like electrodes on all of said processing chambers are electrically connected to each other.
