  • Publication number: 20240105429
    Abstract: A substrate support includes an edge ring, a heater element arranged within the edge ring, a ceramic layer, at least one heating element arranged within the ceramic layer, and a cable configured to provide power from a power source to the heater element and the at least one heating element. The cable includes a first plurality of wires connected to the heater element, a second plurality of wires connected to the at least one heating element, a filter module, and an isolation device connected only to the first plurality of wires between the filter module and the heater element. The first and second pluralities of wires are twisted together within the filter module. The isolation device is configured to compensate for a resonance frequency generated during operation of the heater element and the at least one heating element.

  • Publication number: 20180005851
    Abstract: A chamber filler kit for balancing electric fields in a dielectric etch chamber is provided. A transport module filler comprises an electrical conductive body, an etch resistant surface, wherein the etch resistant surface comprises an inner curved surface, which matches a partial cylindrical bore of the etch chamber, and a wafer transport aperture, wherein the transport module filler fits into a transport aperture of the etch chamber. A transport module sealer plate is adapted to be mechanically and electrically connected to the partially cylindrical chamber body and the transport module filler. A bias housing filler is adapted to be mechanically and electrically connected to a bias housing wall and comprises a conductive body and an etch resistant surface, wherein the etch resistant surface comprises a curved surface, which matches the partial cylindrical bore.
