Publication number: 20240266151Abstract: Systems and methods for securing an edge ring to a support ring are described. The edge ring is secured to the support ring via multiple fasteners that are inserted into a bottom surface of the edge ring. The securing of the edge ring to the support ring provides stability of the edge ring during processing of a substrate within a plasma chamber. In addition, the securing of the edge ring to the support ring secures the edge ring to the plasma chamber because the support ring is secured to an insulator ring, which is connected to an insulator wall of the plasma chamber. Moreover, the support ring and the edge ring are pulled down vertically using one or more clasp mechanisms during the processing of the substrate and are pushed up vertically using the clasp mechanisms to remove the edge ring and the support ring from the plasma chamber.Type: ApplicationFiled: March 26, 2024Publication date: August 8, 2024Inventors: Michael C. Kellogg, Adam Mace, Alexei Marakhtanov, John Holland, Zhigang Chen, Felix Kozakevich, Alexander Matyushkin

Patent number: 11195706Abstract: Systems and methods for achieving a pre-determined factor associated with the edge region within the plasma chamber is described. One of the methods includes providing an RF signal to a main electrode within the plasma chamber. The RF signal is generated based on a frequency of operation of a first RF generator. The method further includes providing another RF signal to an edge electrode within the plasma chamber. The other RF signal is generated based on the frequency of operation of the first RF generator. The method includes receiving a first measurement of a variable, receiving a second measurement of the variable, and modifying a phase of the other RF signal based on the first measurement and the second measurement. The method includes changing a magnitude of a variable associated with a second RF generator to achieve the pre-determined factor.Type: GrantFiled: April 15, 2019Date of Patent: December 7, 2021Assignee: Lam Research CorporationInventors: Alexei Marakhtanov, Felix Kozakevich, Michael C.
