1.Functions

Central process recipe execution This motherboard serves as the core computing unit of Lam plasma processing tool. It loads and runs wafer etch process recipes, schedules all process steps, and coordinates sub-modules including RF generator, gas delivery, vacuum subsystem, wafer transfer and chamber peripherals.www.plcva.com
System-wide data acquisition & closed-loop process control It collects real-time data from pressure, temperature, gas flow, plasma monitoring sensors and sub-control boards. It calculates process deviations and outputs control commands to maintain stable etch parameters for consistent wafer processing performance.
Integrated equipment communication bus management It communicates with HMI, chamber I/O boards, motion control boards, RF power supply modules via internal industrial bus. It synchronizes command and feedback signals between host and all subordinate hardware subsystems.
Fault management, data logging & process traceability Monitors system health continuously. It captures equipment alarms, fault events and process runtime data, stores logs locally and uploads information to fab host computer for recipe audit, failure diagnosis and wafer lot traceability.
Global safety interlock coordination It receives interlock signals from chamber door, E-stop, vacuum and gas safety sensors. It issues high-level system interlock commands to halt process, cut off RF power and shut gas supply when unsafe conditions are detected.www.plcva.com
