Title: Plasma treatment device and plasma treatment method
Inventor: ICHIMURA SATOSHI
IPC: C23F4/00
Filed: 2000-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain a plasma treatment device and a method, which enables dimensional reduction of permanent magnets and cost reduction of the device, can be surely utilized for processing a magnetic film and can generate an uniform plasma stably over a wide range. SOLUTION: A magnetic field with an intensity exceeding the intensity of an electron cyclotron resonance magnetic field is generated in an electron heating space chamber by permanent magnets 3. Since the magnetic field intensity is zero at the points near the boundary between the electron heating space chamber and a plasma generating space chamber 2, the magnetic field intensity distribution generated by the permanent magnets 3 is attenuated sharply. Therefore, most of the microwaves are absorbed by electrons to heat the electrons at the positions of electron cyclotron layers, so that high energy electrons can be obtained.
