  • Publication number: 20230386795
    Abstract: Disclosed herein are surface coatings for plasma components that have the benefit of being robust against chemical recombination rates for active oxygen, nitrogen, fluorine, and hydrogen species when compared with other known surface treat ments. The coatings can be applied to any plasma system component not requiring etching or plasma cleaning including but not limited to materials like quartz, aluminum, or anodized aluminum. Additionally, the efficiency of the system is increased by applying a non-reactive coating to system components thereby increasing the flow of excited plasma species to the plasma chamber of the system.

  • Publication number: 20230337407
    Abstract: A conductive polymeric layer on an electrostatic chuck. The conductive polymeric layer comprises a conductive polymer and a photosensitive polymer. The conductivity of the conductive polymer promotes charge dissipation by the conductive polymeric layer, while the photosensitivity of the photosensitive polymer allows the surface of the conductive polymeric layer to be photopatterned. The extent to which the conductive polymeric layer is conductive and photosensitive may be modulated by varying the relative amounts of the conductive polymer and the photosensitive polymer.

  • Patent number: 11764037
    Abstract: Disclosed herein are surface coatings for plasma components that have the benefit of being robust against chemical and plasma physical attack in aggressive (e.g., fluorine-based) plasma environments. The coatings also provide low plasma surface recombination rates for active oxygen, nitrogen, fluorine, and hydrogen species when compared with other known surface treatments. The coatings can be applied to any plasma system component not requiring etching or plasma cleaning including but not limited to materials like quartz, aluminum, or anodized aluminum. Additionally, the efficiency of the system is increased by applying a non-reactive coating to system components thereby increasing the flow of excited plasma species to the plasma chamber of the system.

  • Publication number: 20230287564
    Abstract: A device which can be exposed to chemical vapors, such as a molybdenum vapor, a tungsten vapor, or any combination thereof, which has a coating covering at least a portion thereof. The coating reduces or inhibits mass change at an outer surface of the device from exposure to the vapor. In certain situations, the mass change is a mass gain, and the coating reduces or inhibits the mass gain of equal to or less than 1×10?5 g mm?2.

  • Publication number: 20230093910
    Abstract: Some embodiments relate to additive manufactured articles having passivated surfaces and related methods. The methods may comprise forming a three-dimensional (3D) article by additive manufacturing to obtain an additive manufactured 3D article comprising a magnesium component. The method may further comprise exposing the additive manufactured 3D article to a reactive gas phase comprising a fluorine component. The fluorine component from the reactive gas phase may react with the magnesium component of the additive manufactured 3D article to form a passivation layer at and below a surface of the additive manufacture 3D article.
