    Abstract: Electrostatic chucks (ESCs) for plasma processing chambers, and methods of fabricating ESCs, are described. In an example, a substrate support assembly includes a ceramic bottom plate, a ceramic top plate, and a bond layer between the ceramic top plate and the ceramic bottom plate, the ceramic top plate in direct contact with the bond layer, and the bond layer in direct contact with the ceramic bottom plate. A metal shaft is coupled to the ceramic bottom plate at a side of the ceramic bottom plate opposite the bond layer.

    Abstract: Gas distribution apparatus, processing chambers and methods using a dead volume-free valve are described. The valve has a first inlet line with upstream and downstream ends and a second inlet line with a downstream end that connects to the first inlet line. A sealing surface at the downstream end of the second inlet line separates the first inlet line from the second inlet line preventing fluid communication between the first inlet line and the second inlet line.
