Abstract
A plasma processing method includes forming a silicon oxide film on a surface of a member provided within a chamber with plasma of a silicon-containing gas without oxygen while controlling a temperature of the member to be lower than a temperature of another member; performing a plasma process on a target object loaded into the chamber with plasma of a processing gas after the silicon oxide film is formed on the surface of the member; and removing the silicon oxide film from the surface of the member with plasma of a fluorine-containing gas after the target object on which the plasma process is performed is unloaded to an outside of the chamber.
