Plasma processing device

Abstract

Abstract PURPOSE: To enable generating of a plasma current along a reaction vessel, by a method wherein a static magnetic field, being uneven in an axial direction, is generated in the plasma reaction vessel using an air-core coil, and a high-frequency magnetic field, being uneven in an axial direction, is added further through a high-frequency waveguide. CONSTITUTION: An air-core coil 1, generating a static magnetic field being uneven in an axial direction, and a high-frequency guidewave 2, producing a high- frequency magnetic field uneven in an axial direction, are mounted around a plasma generating glass tube 3 to constitute a plasma generating part A. If the high-frequency guidwave 2 generates a magnetic field having a magnetic field satisfying a cyclone resonance condition of an electron, an electron in the glass tube 3 is accelerated, and a plasma so produced is fed to a magnetic field through the polarization of the electron to produce a plasma current flowing along the glass tube 3 and to flow out to a plasma reaction part B. The plasma is shaped using coils 14 and 15, and a substrate 10, placed on a stand 9, is irradiated with the plasma so shaped. COPYRIGHT: (C)1982,JPO&Japio
