Abstract:
A vacuum processing method of processing at least one object to be processed with an oxygen radical in a processing chamber defined by a vacuum vessel of a vacuum processing apparatus, which comprises the steps of:a) activating a fluorinating gas containing at least a fluorine atom and a gas containing at least an oxygen atom in a plasma producing chamber separated from the processing chamber for producing a fluorine radical; b) supplying the fluorine radical and the oxygen radical into the processing chamber, not yet containing said at least one object to be processed; c) fluorinating a surface of a component of the processing apparatus, said component being formed of an organic material and exposed to an atmosphere in the processing chamber with the fluorine radical; d) moving the at least one object to be processed into the processing chamber after the surface of the component has been fluorinated; and e) processing the at least one object to be processed with an oxygen radical produced by activating a process gas in the plasma producing chamber.
