  • Publication number: 20230296512
    Abstract: The present invention generally relates method and apparatus for detecting erosion to a ring assembly used in an etching or other plasma processing chamber. In one embodiment, a method begins by obtaining a metric indicative of wear on a ring assembly disposed on a substrate support in a plasma processing chamber prior to processing with plasma in the plasma processing chamber. The metric for the ring assembly is monitored with a sensor. A determination is made if the metric exceeds a threshold and generating a signal in response to the metric exceeding the threshold.

  • Patent number: 11433436
    Abstract: Disclosed herein is a sonic cleaning insert. In one example, the sonic cleaning insert includes a carousel configured to rotate about a central axis. The carousel further includes a platform having an outer perimeter. The platform is radially disposed about the central axis. The carousel has an inner ring and an outer ring circumscribing the inner ring. A plurality of partitions couple the inner ring and the outer ring to the platform. The plurality of partitions are arranged at a predetermined angle about the central axis. The carousel further includes a plurality of holders. Each holder is formed from a portion of the platform, a portion of each of the inner ring and outer ring, and a first sidewall and a second sidewall formed from the plurality of partitions. The carousel is configured for immersion in an ultrasonic vibrating fluid.

  • Patent number: 11370083
    Abstract: A pad conditioner head cleaning tool has a first clamp configured to removably engage a first portion of a sponge against an outer surface of a disk-shaped pad conditioner head at a first location, a second clamp configured to removable engage a second portion of the sponge against the outer surface of the disk-shaped pad conditioner head at a second location, and an arm coupling the first clamp to the second clamp. The arm is sufficiently flexible to permit the first clamp and the second clamp to be separated to fit around the disk-shaped pad conditioner head and sufficiently tensile to bias the first clamp and the second clamp inwardly to press the sponge against an outer surface of a pad conditioner head.
