Patent ID: 8070925

Claim:
A plasma reactor comprising: a reactor chamber comprising a ceiling, a sputter target adjacent said ceiling and a wafer support pedestal within the chamber facing said sputter target; a conductive housing overlying said ceiling and having a top lid facing said coiling; a rotating magnet assembly contained within said housing and comprising a rotatable spindle, a radial arm assembly coupled at, an inner end to said spindle, and a magnet coupled to an outer end of said radial arm assembly, said top lid of said housing comprising a central port, said spindle extending axially through said central port; a conductive hollow cylinder on said top lid and surrounding a portion of said spindle that extends above said top lid; a radial RF connection rod having a first radially inward end connected to said hollow cylinder and a first radially outward end, said radial RF connection rod extending radially outwardly from said hollow cylinder to said first radially outward end; an RF power source comprising an RF generator and an RF impedance match, said impedance match being connected to said first radially outward end of said radial RF connection rod; and a grounded conductive shield enclosure outside of and surrounding said conductive housing and said conductive hollow cylinder, said radial RF connection rod penetrating and insulated from said grounded conductive shield enclosure.
