  • Publication number: 20180265973
    Abstract: Described herein are articles, systems and methods where a plasma resistant coating is deposited onto a surface of a porous chamber component and onto pore walls within the porous chamber component using an atomic layer deposition (ALD) process. The porous chamber component may include a porous body comprising a plurality of pores within the porous body, the plurality of pores each comprising pore walls. The porous body is permeable to a gas. The plasma resistant coating may comprise a solid solution of Y2O3—ZrO2 and may have a thickness of about 5 nm to about 3 ?m, and may protect the pore walls from erosion. The porous body with the plasma resistant coating remains permeable to the gas.

  • Patent number: 9597734
    Abstract: Embodiments of the present disclosure generally provide chamber components with enhanced thermal properties and methods of enhancing thermal properties of chamber components including bonding materials. One embodiment of the present disclosure provides a method for fabricating a composite structure. The method includes applying a bonding material to a first component, and converting the bonding material applied to the first component to an enhanced bonding layer by heating the bonding material to outgas volatile species from the bonding material. The outgassed volatile species accumulates to at least 0.05% in mass of the bonding material. The method further includes contacting a second component and the enhanced bonding layer to join the first and second components.
