    Abstract: A method of plasma spraying an article comprises inserting the article into a vacuum chamber for a low pressure plasma spraying system. A low pressure plasma spray process is then performed by the low pressure plasma spraying system to form a first plasma resistant layer having a thickness of 20-500 microns and a porosity of over 1%. A plasma spray thin film, plasma spray chemical vapor deposition or plasma spray physical vapor deposition process is then performed by the low pressure plasma spraying system to deposit a second plasma resistant layer on the first plasma resistant layer, the second plasma resistant layer having a thickness of less than 50 microns and a porosity of less than 1%.

    Abstract: An electrostatic chuck (ESC) including a ceramic body having a first surface with two or more regions defined on the first surface arranged concentrically with respect to each other on the first surface. Each region includes a retaining ring arranged on the first surface and defining an outer edge of the region, and structures arranged on the first surface and within the region configured to support a surface of a substrate when the substrate is retained by the electrostatic chuck. The ESC includes gas conduits configured to introduce a gas into the two or more regions through the ceramic body and to the first surface, and embedded electrodes within the ceramic body and arranged with respect to the first surface and configured to generate a retaining force on the surface of the substrate.
