Abstract: PURPOSE:To extract an ion beam from a region having the highest plasma density distribution by providing the arrangement position of an ion extracting electrode, which is arranged on the center axis of a plasma generating chamber and near a plasma outflow port, near the region having the highest plasma density. CONSTITUTION:A plasma generating chamber 11 is vacuum-sealed by a microwave guiding window 12, and the gas to be ionized is guided through a gas guiding port 15. Microwaves are guided into the plasma generating chamber 11 through the microwave guiding window 12 from a rectangular waveguide 13, and a magnetic coil 14 is arranged so that the maximum magnetic field is generated between the microwave guiding window 12 and near the center of the plasma generating chamber 11 and the weak divergent magnetic field is generated toward an ion extracting electrode system 17. The generated plasma is shifted toward the ion extracting electrode system 17 due to the divergent magnetic field of the magnetic coil 14 and also by the electric field of the plasma itself and the gas flow in-flowing through the gas guiding port 15. Accordingly, high-density ion plasma can be radiated, and its processing speed can be increased.
