摘要:
Systems for prequalifying components for a processing chamber are described. The systems may be used to clean particulates from chamber parts and concurrently quantify the cleanliness. The systems may be used to qualify replacement parts before sending to a customer site for installation. The systems have three adjacent compartments separated by impermeable barriers. All three compartments are filled with liquid while cleaning a chamber component. The center compartment contains a submerged component for cleaning and qualifying. Two compartments on either side of the center compartment are configured with submerged ultrasonic transducers to deliver ultrasonic energy to either side of the component being cleaned and prequalified. A liquid pump is connected to the cleaning tub to recirculate water from the cleaning bath and another liquid pump is configured to remove a small amount of the cleaning bath to sample particulates.
