Publication number: 20240379343Abstract: Embodiments of the disclosure relate to methods for reducing or eliminating the first wafer effect after chamber cleans for plasma etch processes. In some embodiments, the wafer support is maintained at an elevated temperature relative to the etch process. In some embodiments, the etch process is a NF3+NH3 plasma etch to remove native oxides from a silicon substrate.Type: ApplicationFiled: May 10, 2024Publication date: November 14, 2024Applicant: Applied Materials, Inc.Inventors: Yongqian Gao, Michael S. Jackson, David T. Or, Chun-Chieh Wang, Le Zhang

Publication number: 20240367113Abstract: Methods of preparing a porous robust support to host an ultra-thin enzyme-assisted membrane, and a new membrane system that can be used for gas filtration purposes to remove/separate carbon dioxide or other gases from a gas mixture such as those from power production or enhanced oil recovery or fuel production or air and recycle/collect/utilize carbon dioxide are disclosed herein. A method may include protecting the surface with a blocking material and polishing the protected surface, coating a thin layer of silica nanospheres onto the polished surface, coating a silica sol-gel and surfactant solution onto the nanospheres, and then removing the surfactant and blocking material to generate a well-defined porous structure with nanochannels.Type: ApplicationFiled: May 1, 2023Publication date: November 7, 2024Applicant: Memzyme, LLCInventors: Yongqian Gao, Rong-An Chiang, Christopher P. Beamis

Publication number: 20240304495Abstract: A method of forming a semiconductor device structure by utilizing a hydrogen plasma treatment to promote selective deposition is disclosed. In some embodiments, the method includes forming a metal layer within at least one feature on the semiconductor device structure. The method includes exposing the metal layer to a hydrogen plasma treatment. The hydrogen plasma treatment preferentially treats the top field and sidewalls while leaving the bottom surface substantially untreated to encourage bottom up metal film growth. In some embodiments, the hydrogen plasma treatment comprises substantially only hydrogen ions.Type: ApplicationFiled: March 6, 2023Publication date: September 12, 2024Applicant: Applied Materials, Inc.Inventors: Tsung-Han Yang, Zhen Liu, Yongqian Gao, Michael S. Jackson, Rongjun Wang

Patent number: 11986774Abstract: Disclosed are methods of preparing a porous ceramic support for an ultra-thin enzyme-assisted membrane, and a new membrane that can be used for gas filtration purposes to remove/separate carbon dioxide or other gases from a gas mixture such as those from power production or enhanced oil recovery or fuel production or air, and recycle/collect/utilize carbon dioxide. In some embodiments, a method may include blocking the pores of a porous substrate with a removable medium, and polishing the surface, coating a silica sol-gel solution onto the support, and removing the blocking medium and sol-gel surfactant to leave a well-confined porous structure.Type: GrantFiled: March 17, 2022Date of Patent: May 21, 2024Assignee: Memzyme, LLCInventors: Caroline Rempe, Ying-Bing Jiang, Yongqian Gao, Jimin Guo

Publication number: 20240014072Abstract: A method of forming a semiconductor device structure includes forming a nucleation layer within at least one feature. The method includes exposing the nucleation layer to a nitrogen plasma treatment. The nitrogen plasma treatment preferentially treats the top field and sidewalls while leaving the bottom surface substantially untreated to encourage bottom up metal growth.Type: ApplicationFiled: June 21, 2023Publication date: January 11, 2024Inventors: Tsung-Han YANG, Zhimin QI, Yongqian GAO, Rongjun WANG, Yi XU, Yu LEI, Xingyao GAO, Chih-Hsun HSU, Xi CEN, Wei LEI, Shiyu YUE, Aixi ZHANG, Kai WU, Xianmin TANG

Publication number: 20130212570Abstract: A method and apparatus for determining a state of a computing device are provided. At least one unique code associated with at least one file resident on the computing device is determined, the at least one unique code representative of a state of the at least one file. At least one unique reference code associated with at least one update file is determined, the at least one update file for updating the at least one file. The at least one unique reference code is representative of an expected state of the at least one file. The state of the computing device is determined to be in an expected state if the at least one unique code matches the at least one unique reference code, and in an unexpected state if the at least one unique code does not match the at least one unique reference code.Type: ApplicationFiled: August 13, 2012Publication date: August 15, 2013Inventors: Spencer QUIN, Yongqian Gao
