摘要: A method and apparatus for substrate processing and a cluster tool including a transfer chamber assembly and a plurality of processing assemblies. Processing chamber volumes are sealed from the transfer chamber volume using a support chuck on which a substrate is disposed. A seal ring assembly is coupled to the support chuck. The seal ring assembly includes an inner assembly, an assembly bellows circumscribing the inner assembly, and a bellows disposed between the inner and outer platform. An inner ring is disposed between inner assembly of the seal ring assembly and the bottom surface of the support chuck. An outer ring disposed between the seal ring assembly and the lower sealing surface of the process chamber wall. The support chuck is raised to form an isolation seal between the processing chamber volume and the transfer chamber volume using the bellows, the inner ring, and the outer ring.

摘要: Aspects of the present disclosure provide systems and apparatuses for a substrate processing assembly with a laminar flow cavity gas injection for high and low pressure. A dual gas reservoir assembly is provided in a substrate processing chamber, positioned within a lower shield assembly. A first gas reservoir is in fluid communication with a processing volume of the substrate processing assembly via a plurality of gas inlet, positioned circumferentially about the processing volume. A second gas reservoir is positioned circumferentially about the first gas reservoir, coupled therewith via one or more reservoir ports. The second gas reservoir is in fluid communication with a first gas source. A recursive path gas assembly is positioned in an upper shield body adjacent to an electrode to provide one or more gases to a dark space gap.

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.
