Patent number: 11866821Abstract: 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.Type: GrantFiled: March 2, 2020Date of Patent: January 9, 2024Assignee: Applied Materials, Inc.Inventors: Shuran Sheng, Lin Zhang, Jiyong Huang, Joseph C. Werner, Stanley Wu, Mahesh Adinath Kanawade, Yikai Chen, Yixing Lin, Ying Ma

Publication number: 20210280389Abstract: Embodiments disclosed herein generally relate to a plasma processing system for modifying the uniformity pattern of a thin film deposited in a plasma processing chamber which includes at least one VHF power generator coupled to a diffuser within the plasma processing chamber. The feeding location offset of each VHF power generator and the controlling of each VHF power generator via phase modulation and sweeping allows for plasma uniformity improvements by compensating for the non-uniformity of the thin film patterns produced by the chamber, due to the standing wave effect. The power distribution between the multiple VHF power generators coupled to and/or disposed at different locations on the backing plate may be produced by dynamic phase modulation between the VHF power applied at the different coupling points.Type: ApplicationFiled: July 31, 2017Publication date: September 9, 2021Applicant: Applied Materials, Inc.Inventors: Shuran SHENG, Shinobu ABE, Keita KUWAHARA, Su Ho CHO
