Abstract

A substrate processing apparatus generates an electric field in a processing space between a lower electrode to which a high frequency power is supplied and an upper electrode facing the lower electrode and performs plasma processing on a substrate mounted on the lower electrode by using a plasma generated by the electric field. Distribution of a plasma density in the processing space is controlled by a magnetic field generated by controlling a plurality of electromagnets provided at a top surface of the upper electrode which is provided to be opposite to the processing space.
