Abstract:
An apparatus for plasma processing a substrate is provided. The apparatus comprises a processing chamber, a substrate support disposed in the processing chamber, a shield member disposed in the processing chamber below the substrate support, and a lid assembly coupled to the processing chamber. The lid assembly comprises a conductive gas distributor coupled to a power source, and an electrode separated from the conductive gas distributor and the chamber body by electrical insulators. The electrode is also coupled to a source of electric power. The substrate support is formed with a stiffness that permits very little departure from parallelism. The shield member thermally shields a substrate transfer opening in the lower portion of the chamber body. A pumping plenum is located below the substrate support processing position, and is spaced apart therefrom.

Abstract:
A flexible polymer or elastomer coated RF return strap to be used in a plasma chamber to protect the RF strap from plasma generated radicals such as fluorine and oxygen radicals, and a method of processing a semiconductor substrate with reduced particle contamination in a plasma processing apparatus. The coated RF strap minimizes particle generation and exhibits lower erosion rates than an uncoated base component. Such a coated member having a flexible coating on a conductive flexible base component provides an RF ground return configured to allow movement of one or more electrodes in an adjustable gap capacitively coupled plasma reactor chamber.
