Abstract
An apparatus for forming thin films such as protective layers on both surfaces of a substrate of a magnetic memory device has an evacuable reaction chamber sandwiched between two electron cyclotron resonance plasma generators disposed on mutually opposite sides. Each plasma generator includes a wave guide for introducing microwave energy and a magnetic coil for providing a magnetic field for generating a plasma and causing the generated plasma to move to the substrate set inside the reaction chamber with a negative bias voltage applied thereto.
