  • Patent number: 11866821
    Abstract: Embodiments of the present disclosure generally relate to an apparatus and a method for cleaning a processing chamber. In one embodiment, a substrate support cover includes a bulk member coated with a fluoride coating. The substrate support cover is placed on a substrate support disposed in the processing chamber during a cleaning process. The fluoride coating does not react with the cleaning species. The substrate support cover protects the substrate support from reacting with the cleaning species, leading to reduced condensation formed on chamber components, which in turn leads to reduced contamination of the substrate in subsequent processes.

  • Publication number: 20230238267
    Abstract: Methods and apparatus reduce chucking abnormalities for electrostatic chucks by ensuring proper planarizing of ceramic surfaces of the electrostatic chuck. In some embodiments, a method for planarizing an upper ceramic surface of an electrostatic chuck assembly may comprise placing the electrostatic chuck assembly in a first planarizing apparatus, altering an upper ceramic surface of the electrostatic chuck assembly, and halting the altering of the upper ceramic surface of the electrostatic chuck assembly when an Sa parameter is less than approximately 0.1 microns, an Sdr parameter is less than approximately 2.5 percent, an Sz parameter is less than approximately 10 microns for any given area of approximately 10 mm2 of the upper ceramic surface, or a pit-porosity depth parameter of greater than 1 micron is less than approximately 0.1 percent of area of the upper ceramic surface.

  • Publication number: 20230229677
    Abstract: A data linking system is described herein that links data records corresponding to a particular real estate property even if there are inconsistencies in the data records, the physical presence of the real estate property has changed over time, and/or the data records use different terminology. In some cases the data records are matched using a trained machine learning model. The data linking system can optionally generate a visualization of the data record linkage via interactive user interfaces. By linking data records despite the issues described above, the data linking system reduces the number of navigational steps a user performs to obtain data associated with a property and/or reduces data processing times. The disclosed system may be used to generate and maintain a comprehensive database of substantially all properties within a jurisdiction, in which a unique identifier is assigned to each property.
