  • Method and apparatus for cleaning surfaces with a glow discharge plasma at one atmosphere of pressure
    Patent number: 5938854
    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.
