Abstract:
1. A plasma processing chamber for processing a substrate to form electronic components thereon, comprising: a plasma-facing component having a plasma-facing surface oriented toward a plasma in said plasma processing chamber during processing of said substrate, said plasma-facing component representing a cylindrical chamber wall and being electrically isolated from a ground terminal; and a grounding arrangement coupled to said plasma-facing component, said grounding arrangement including a first resistance circuit and an RF filter arrangement; disposed in a first current path between said plasma-facing component and said ground terminal, said grounding arrangement further including a plurality of RF filter arrangements disposed in a plurality of current paths between said plasma-facing component and said ground terminal, said plurality of RF filter arrangements being arranged so as to improve distribution of capacitive grounding of said plasma-facing component with respect to at least one surface of said plasma-facing component wherein a resistance value of said first resistance circuit is selected to substantially eliminate arcing between said plasma and said plasma-facing component during said processing of said substrate.
