Claim 0:
1. A plasma processing apparatus, comprising:
a processing container having a vertical tubular shape and an opening formed in a side wall of the processing container, the processing container configured to accommodate a plurality of substrates in multiple stages;
a plasma partition wall airtightly provided on an outer wall of the processing container and configured to cover the opening and define a plasma generation space;
a plasma electrode provided along the plasma partition wall;
a processing gas nozzle provided outside the plasma generation space and inside the processing container, and configured to supply a plasma generation gas; and
a controller programmed to execute:
supplying the plasma generation gas into the processing container by the processing gas nozzle;
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 the plasma electrode; and
supplying the active species into the processing container via the opening.
