    摘要: The invention provides a plasma processing apparatus in which ring-like conductors 8a and 8b are arranged closed to and along an induction antenna 1 composed of an inner circumference coil 1a and an outer circumference coil 1b. Ring-like conductors 8a and 8b are each characterized in that the radius from the center of the apparatus and the cross-sectional shape of the conductor body varies along the circumferential angle of the coils. Since the mutual inductances between the ring-like conductors 8a and 8b and the induction antenna 1 and between the ring-like conductors 8a and 8b and the plasma along the circumferential position are controlled, it becomes possible to compensate for the coil currents varied along the circumference of the coils of the induction antenna 1, and to improve the non-uniformity in the circumferential direction of the current in the generated plasma.

    摘要: A uniform plasma processing to a sample is performed by adjusting the distribution of the induced magnetic field in an inductively-coupled-plasma processing apparatus and correcting the plasma distribution on the sample. Between an induction coil and a dielectric window a conductor is provided along the induction coil and side by side with at least a part of the induction coil in its circumferential direction. The conductor is set up at a location where the intensity of the induced magnetic field generated from the induction coil is wished to be weakened and the relationship of Lp≧Lr is satisfied, letting the shortest distance from the induction coil to the surface of the conductor be Lr and letting the shortest distance from the induction coil to the plasma generated directly under the dielectric window be Lp.
