Patent number: 12620555Abstract: A method of performing a plasma process includes generating, at an output of a signal generator, a first RF signal at a first frequency. The signal generator is coupled to a plasma chamber through a matching circuit. Based on a feedback from the first RF signal, variable components of the matching circuit are moved to fixed positions. A second RF signal is generated at a second frequency at the output of the signal generator to ignite a plasma within the plasma chamber. In response to detecting the plasma, the signal generator switches to output a third RF signal at the first frequency to sustain the plasma, which is configured to process a substrate loaded into the plasma chamber while holding the matching circuit at the fixed positions.Type: GrantFiled: May 27, 2022Date of Patent: May 5, 2026Assignee: TOKYO ELECTRON LIMITEDInventors: Charles Schlechte, Jianping Zhao, John Carroll, Peter Lowell George Ventzek
