Claim 8:
9. A plasma processing method, comprising:
accommodating a plurality of substrates in multiple stages inside a processing container having a vertical tubular shape and an opening formed in a side wall of the processing container;
supplying a plasma generation gas into the processing container by a processing gas nozzle provided outside a plasma generation space, which is defined by a plasma partition wall airtightly provided on an outer wall of the processing container to cover the opening, and inside the processing container;
causing the plasma generation gas supplied into the processing container to be diffused into the plasma generation space via the opening;
converting the plasma generation gas into plasma to generate active species in the plasma generation space by supplying an RF power to a plasma electrode provided along the plasma partition wall; and
supplying the active species into the processing container via the opening.
