Abstract:
1. A method for configuring a plasma processing chamber for processing a substrate to form electronic components thereon, said plasma processing chamber including at least a plasma-facing component, said plasma-facing component having a plasma-facing surface oriented toward a plasma in said plasma processing chamber during said processing said substrate, said method comprising: electrically isolating said plasma-facing component from a ground terminal; coupling said plasma-facing component to a grounding arrangement, said grounding arrangement comprising a first resistance circuit disposed in a first current path between said plasma-facing component and said ground terminal; including an RF filter arrangement in said grounding arrangement; coupling said first resistance circuit in parallel with said RF filter arrangement; and distributing a plurality of wall-contacting modules along a circumference of said plasma-facing component, each wall-contacting module of said plurality of wall-contacting modules including a conductive base and a resistor-capacitor module, said resistor-capacitor module being electrically coupled with said conductive base through a first conductor and being disposed on said conductive base, said resistor-capacitor module including at least a resistor and a capacitor, said resistor being electrically coupled in parallel with said capacitor; attaching said conductive base to an exterior surface of said plasma-facing component, said external surface of said plasma-facing component being opposite to said plasma-facing surface; and electrically grounding said resistor-capacitor module through a second conductor.
