Abstract:
A plasma processing apparatus comprising:a processing chamber; a susceptor having a supporting area on which a substrate to be processed is supported in the processing chamber; a spiral antenna being arranged to substantially face the supporting area of the susceptor; a dielectric member interposed between the spiral antenna and the supporting area of the susceptor; and a high frequency power supply electrically connected to a central area of the spiral antenna for supplying a high frequency power to the spiral antenna from the central area thereof so as to generate plasma in the processing chamber for processing the substrate to be processed; said spiral antenna including at least two elongated members, each outwardly extending from the central area and having an inner end portion and an outer end portion, the inner end portion being positioned on the central area and at least one inner end portion being electrically connected to the high frequency power supply.
