摘要: In one example, an electrostatic chuck comprises a chuck body having a top surface configured to support a substrate and a bottom surface opposite the top surface. The chuck body comprises one or more chucking electrodes, and one or more heating elements. The chuck body further comprises first terminals disposed on the bottom surface of the chuck body and coupled with the one or more heating elements, second terminals disposed on the bottom surface of the chuck body and coupled with the one or more chucking electrodes, and third terminals disposed on the bottom first surface of the chuck body and coupled with the one or more chucking electrodes.

摘要: A physical vapor deposition processing chamber is described. The processing chamber includes a target backing plate in a top portion of the processing chamber, a substrate support in a bottom portion of the processing chamber, a deposition ring positioned at an outer periphery of the substrate support and a shield. The substrate support has a support surface spaced a distance from the target backing plate to form a process cavity. The shield forms an outer bound of the process cavity. In-chamber cleaning methods are also described. In an embodiment, the method includes closing a bottom gas flow path of a processing chamber to a process cavity, flowing an inert gas from the bottom gas flow path, flowing a reactant into the process cavity through an opening in the shield, and evacuating the reaction gas from the process cavity.

摘要: A pedestal assembly for a processing region and comprising first pins coupled to a substrate support, configured to mate with first terminals of an electrostatic chuck, and are configured to be coupled to a first power source. Each of the first pins comprises an interface element, and a compliance element supporting the interface element. Second pins are coupled to the substrate support, configured to mate with second terminals of the electrostatic chuck, and configured to couple to a second power source. Alignment elements are coupled to the substrate support and are configured to interface with centering elements of the electrostatic chuck. The flexible element is coupled to the substrate support, configured to interface with a passageway of the electrostatic chuck, and configured to be coupled to a gas source.
