Abstract:
A plasma processing apparatus comprising:a plasma chamber in which a plasma is produced;a microwave introducing unit which introduces microwaves into said plasma chamber to produce plasma;a first permanent magnet disposed in a periphery of said microwave introducing unit and generating a magnetic field having an intensity of electron cyclotron resonance for producing plasma by an interaction with said microwaves;second permanent magnets disposed in a periphery of said plasma chamber and adjacent ones of said plurality of second permanent magnets having opposite polarities for producing a cusped magnetic field; anda support supporting an object processed by plasma,wherein said microwave introducing unit is disposed at a side wall of said plasma chamber, said object processed by plasma is disposed at a position orthogonal to a microwave introducing direction, a microwave is introduced from a side wall between said object and an upper wall, and a plasma, which processes said object, is confined within a space between said object and said upper wall.
