ABSTRACT:
The surface of a workpiece is cleaned by generating a steady-state one atmosphere glow discharge plasma above the surface of the workpiece. The use of one atmosphere, uniform glow discharge plasmas generated by a low frequency RF ion trapping mechanisms is preferred. The plasma used to effect surface cleaning may be formed in atmospheric air or other gases at about one atmosphere of pressure, or at pressures below or above one atmosphere.
