  • Publication number: 20250218774
    Abstract: A method comprises a plurality of cycles, wherein each cycle, comprises exposing the carbon containing etch layer to oxygen radicals to modify part of the carbon containing etch layer. The carbon containing etch layer is exposed to bombardment ions with an energy greater than 100 eV for less than 0.5 seconds, wherein the bombardment ions remove the modified part of the carbon containing etch layer to form etched features.

  • Patent number: 10903065
    Abstract: A chamber is formed to enclose a processing region. A passageway is configured to provide for entry of a substrate into the processing region and removal of the substrate from the processing region. A substrate support structure is disposed within the processing region and configured to support the substrate within the processing region. At least one gas input is configured to supply one or more gases to the processing region. At least one gas output is configured to exhaust gases from the processing region. A humidity control device is configured to control a relative humidity within the processing region. At least one heating device is disposed to provide temperature control of the substrate within the processing region. The processing region of the chamber is directly accessible from a substrate handling module configured to operate at atmospheric pressure.
