  • Publication number: 20130015053
    Abstract: Disclosed is an inductively coupled RF plasma source that provides both magnetic confinement to reduce plasma losses and Faraday shielding to suppress parasitic capacitive components. The inductively coupled RF plasma system comprises an RF power source, plasma chamber, an array of permanent magnets, and an antenna array. The plasma chamber is comprised of walls and a dielectric window having an inner and outer surface wherein the inner surface forms a wall of the plasma chamber. The array of parallel conductive permanent magnets is electrically interconnected and embedded within the dielectric window walls proximate to the inner surface and coupled to ground on one end. The permanent magnet array elements are alternately magnetized toward and away from plasma in the plasma chamber to form a multi-cusp magnetic field. The antenna array may be comprised of parallel tubes through which an RF current is circulated. The antenna array is oriented perpendicular to the permanent magnet array.
