  • Patent number: 11898245
    Abstract: Methods and apparatus for a baking chamber for processing a chamber component are provided herein. In some embodiments, a baking chamber includes: an enclosure defining a first chamber, wherein the first chamber comprises: a first chamber body having a first floor and first sidewalls that couple the first floor to a first lid of the first chamber body to define a first interior volume; a first support disposed in the first interior volume; a first gas line disposed in the first interior volume proximate the first lid; a first showerhead disposed between the first gas line and the first support; a first exhaust coupled to the first floor; and a first heater disposed in the first interior volume between the first support and the first floor; and wherein the enclosure includes a door configured to facilitate transferring the chamber component into and out of the enclosure.

  • Patent number: 11532466
    Abstract: Certain embodiments provide a method and non-transitory computer readable medium having instructions that, when executed by a processor of a processing system, cause the processing system to perform a method for improving operation of a semiconductor processing system. The method of part life estimation generally includes obtaining a chamber part having a first surface portion and second surface portion. A data matrix in the first portion of the chamber part is read. The data matrix has raised features. The first portion of the chamber part is cleaned. Wear on the raised features is evaluated. The part is discarded in response to the wear on the raised feature.

  • Patent number: 11359722
    Abstract: A sealing member is provided, including a plurality of nodes and a plurality of antinodes. Each sealing member can be rotated to expose nondamaged lobes for sealing, and prevents the sealing member from falling out of the lobed groove. A chamber is provided, including a groove that the sealing member is placed in. A method of rotating and placing the sealing member is provided, including a rotation to expose nondamaged portions of the sealing member.

  • Patent number: 11074426
    Abstract: The present disclosure relates to systems and methods for semiconductor tool part tracking and kit verification. Data relating to part identification and performance are encoded to a unique code that is encoded into machine-readable form, such as a data matrix. A multi-dimensional array (MDA) of the data matrices of a group of parts is a ‘golden MDA’. When assembled into a kit, the parts are scanned and compared to the golden MDA. If there's a match, a kit unique code is used to generate a kit data matrix. The part data matrix codes are provided to a database to determine if a part combination will cause a coupling effect, based on part usage history.
