ABSTRACT:
A magnetic field enhanced plasma etch reactor system and method of operation is disclosed. In the system and operation, modulated sinusoidal currents are generated and applied 90.degree. out of phase to opposing pairs of series connected electromagnets to produce a modified rotating magnetic field parallel to a substrate processed in the system. The modification of the rotating magnetic field, in turn, results in an improvement in the uniformity of the etch pattern over the upper surface of the substrate.
