Patent number: 12347692Abstract: Embodiments of the present disclosure relates to a wet bench processing including an in-situ pre-treatment prior to performing the first set of wet bench operations. The pre-treatment may include a pre-clean operation and/or a pre-heat operation. The pre-treatment may be performed in one of the existing ONB tanks without requiring adding new tanks to an existing wet bench tool. The pre-clean operation removes particles from a batch of wafers to avoid or reduce cross-contamination and defect issues, thus improving the yield rate of the wet bench process. The pre-heat operation provides better control and stabilize the temperature in the CHB tank to stabilize the process, such as to stabilize an etch rate.Type: GrantFiled: May 12, 2022Date of Patent: July 1, 2025Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Chung-Wei Chang, Bo-Wei Chou, Chin-Ming Lin, Ping-Jung Huang, Pi-Chun Yu, Bi-Ming Yen, Peng Shen
