  • Publication number: 20180330923
    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: 20180269039
    Abstract: A chamber component comprises a body and a plasma sprayed ceramic coating on the body. The plasma sprayed ceramic coating is applied using a method that includes feeding powder comprising a yttrium oxide containing solid solution into a plasma spraying system, wherein the powder comprises a majority of donut-shaped particles, each of the donut-shaped particles having a spherical body with indentations on opposite sides of the spherical body. The method further includes plasma spray coating the body to apply a ceramic coating onto the body, wherein the ceramic coating comprises the yttrium oxide containing solid solution, wherein the donut-shaped particles cause the ceramic coating to have an improved morphology and a decreased porosity as compared to powder particles of other shapes, wherein the improved surface morphology comprises a reduced amount of surface nodules.

  • Publication number: 20180251406
    Abstract: Disclosed herein are methods for fabricating layered ceramic materials via hot pressing. A method includes disposing a powder compact or a ceramic slurry onto a surface of an article, wherein the article is a chamber component of a processing chamber. The powder compact or ceramic slurry is hot pressed against the surface of the article by heating the article and the powder compact or ceramic slurry and applying a pressure of 15-100 Megapascals. The hot pressing sinters the powder compact or ceramic slurry into a sintered ceramic protective layer and bonds the sintered ceramic protective layer to the surface of the article.
