发明名称 PLASMA REACTOR WITH UNIFORM PROCESS RATE DISTRIBUTION BY IMPROVED RF GROUND RETURN PATH
摘要 In a plasma reactor having an RF plasma source power applicator at its ceiling, an integrally formed grid liner includes a radially extending plasma confinement ring and an axially extending side wall liner. The plasma confinement ring extends radially outwardly near the plane of a workpiece support surface from a pedestal side wall, and includes an annular array of radial slots, each of the slots having a narrow width corresponding to an ion collision mean free path length of a plasma in the chamber. The side wall liner covers an interior surface of the chamber side wall and extends axially from a height near a height of said workpiece support surface to the chamber ceiling.
