ABSTRACT:
An oxidizing method for includes: an arranging step of arranging a plurality of objects to be processed in a processing container whose inside can be vacuumed, a supplying unit of an oxidative gas being provided at one end of the processing container, a plurality of supplying units of a reducing gas being provided at a plurality of positions in a longitudinal direction of the processing container; an atmosphere forming step of supplying the oxidative gas and the reducing gas into the processing container in order to form active oxygen species and active hydroxyl species; and an oxidizing step of oxidizing surfaces of the plurality of objects. The atmosphere forming step has: a selecting step of selecting a predetermined supplying unit of a reducing gas among the plurality of supplying units, based on an arrangement number and respective arrangement positions of the plurality of objects; an oxidative-gas supplying step of supplying the oxidative gas into the processing container by means of the supplying unit of an oxidative gas and an reducing-gas supplying step of supplying the reducing gas into the processing container by means of only the supplying unit of a reducing gas selected by the selecting step.
