  • Publication number: 20240264336
    Abstract: Described herein is a method of depositing a conformal, optically transparent coating onto a surface of one or more internal components that are enclosed within an assembled device including an optical encoder using a non-line-of-sight deposition process without altering a structure of the assembled device or impacting functionality of the assembled device. Also described is an assembled device including an optical encoder, where one or more internal components enclosed within the optical encoder and a coating deposited onto a surface of the internal components, where the coating is a conformal, optically transparent coating that is resistant to corrosion by at least one of fluorine-, chlorine-, sulfur-, hydrogen-, bromine-, or nitrogen-based acids and that does not negatively impact functionality of the internal components.

  • Publication number: 20210123143
    Abstract: Embodiments of the present disclosure relate to articles, coated articles, and methods of coating such articles with a corrosion resistant coating. The corrosion resistant coating can comprise hafnium aluminum oxide. The corrosion resistant coating may be deposited by a non-line of sight deposition, such as atomic layer deposition. Articles that may be coated may include chamber components, such as gas lines.

  • Patent number: 10755900
    Abstract: A method of applying a multi-layer plasma resistant coating on an article comprises performing plating or ALD to form a conformal first plasma resistant layer on an article, wherein the conformal first plasma resistant layer is formed on a surface of the article and on walls of high aspect ratio features in the article. The conformal first plasma resistant coating has a porosity of approximately 0% and a thickness of approximately 200 nm to approximately 1 micron. One of electron beam ion assisted deposition (EB-IAD), plasma enhanced chemical vapor deposition (PECVD), aerosol deposition or plasma spraying is then performed to form a second plasma resistant layer that covers the conformal first plasma resistant layer at a region of the surface but not at the walls of the high aspect ratio features.

  • Publication number: 20190376202
    Abstract: An enhanced anodization method includes forming a porous anodization layer comprising columns of anodization layer material with pores between adjacent columns. The method further includes sealing the porous layer by forming a sealing layer at a top of the porous layer. The sealing layer may be formed by using a hybrid sealing process that combines, in any order, two or more of de-ionized (DI) water seal, Ni sealing, and, PTFE sealing. Alternatively, the sealing layer is formed by conformally coating the columns in the porous layer with one or more layers of a coating material. Further, the coating material may be surface-fluorinated to improve plasma resistance.
