LAM 810-102361-222 Chamber Mux Assembly Electrostatic Chuck Control Interface Module

LAM 810-102361-222 is a factory-original Chamber Mux integrated assembly exclusively designed for Lam Research 2300 series semiconductor plasma etching process equipment. 

It is installed directly at the bottom of the reaction chamber electrostatic chuck (ESC), serving as the core electrical and gas distribution switching hub inside the vacuum chamber.

This integrated unit integrates precision printed circuit board, gas solenoid valve distribution pipeline, pin lift drive interface, purge gas switching circuit, temperature sensing 

signal acquisition and high-voltage ESC power isolation circuit. It executes real-time switching of process gas paths, vertical motion control of wafer lift pins, real-time collection of chuck 

temperature feedback signals, transmission of electrostatic chuck high-voltage adsorption control signals, and gas purge protection for chamber internal components during etching recipes execution.

It ensures highly consistent gas flow distribution, stable wafer clamping force and precise lift pin movement throughout multi-step wafer etching processes, directly determining wafer etching uniformity, 

process repeatability and production yield. It is an indispensable critical maintenance spare part for chamber overhaul, fault troubleshooting and component replacement on advanced 

wafer fabrication etching production lines.
