Abstract:
A plasma processing system using a parallel plate type electron cyclotron resonance comprising:a processing mount for mounting a substrate to be processed in a processing container; a planar plate capable of radiating an electromagnetic wave at a position in face-to-face relation with said substrate; a shower plate provided in contact with one side of said planar plate; a first magnetic field-forming means for forming a magnetic field, which is disposed at an outside or inside of said processing container so as to convert a given type of gas to a plasma by aid of the electromagnetic wave; and a second magnetic field-forming means provided with a magnet on the central portion of said planar plate at an opposite side to said one side contacting with said shower plate, for forming a magnetic field different from the magnetic field formed by the first magnetic field-forming means; wherein a direction of a magnetic line of flux in the vicinity of said planar plate is controlled by combination of the magnetic field formed by said first magnetic field-forming means and the magnetic field formed by said second magnetic field-forming means.
