  • Patent number: 8445988
    Abstract: Disclosed is an apparatus and method for plasma processing, which facilitates to constantly control a RF voltage supplied to a substrate supporting member by precisely detecting an inductive RF voltage induced to the substrate supporting member for a plasma, the apparatus comprising: a substrate supporting member for supporting a substrate, installed in a reaction room of a processing chamber; a RF generator for supplying a RF voltage to the substrate supporting member so as to form plasma in the reaction room; and a matching device for matching impedance of the RF voltage to be supplied to the substrate supporting member from the RF generator, wherein the matching device comprises: a matching unit for matching the impedance of RF voltage; and an inductive RF detecting unit which an inductive RF detecting voltage by removing noise frequency elements except a waveform of the RF voltage from a waveform of an inductive RF voltage induced to the substrate supporting member, and supplies the detected inductive RF
