Abstract:
A plasma treatment apparatus comprising:(i) a plurality of reactors each having an evacuatable inside where at least one treatment substrate is set in, and having impedances different from each other; (ii) a high-frequency power supply means for supplying high-frequency power into each reactor having been inside-evacuated, to cause glow discharge to take place in the reactor; and (iii) a plurality of impedance regulation means provided correspondingly to the impedances of the reactors in order to regulate impedances on the side of each reactor and on the side of the high-frequency power supply means, wherein the high-frequency power supply means has an attachment part to which any one of the plurality of impedance regulation means is detachably mountable, and any one of the plurality of impedance regulation means is attached to the attachment part correspondingly to the impedances of the reactors.
