Abstract

A substrate processing method performed by a substrate processing apparatus is provided. The substrate processing method comprises: setting a magnetic pole on a processing space side of each electromagnet belonging to one of first, second and third electromagnet groups to be different from a magnetic pole on the processing space side of each electromagnet belonging to the other two electromagnet groups; generating an electric field by applying a high frequency power to a lower electrode; and performing a first process on the substrate with plasma generated by the electric field.
