1.Functions

Local wafer process sequence control This board acts as a dedicated chamber-level controller. It receives recipe commands from the tool host, executes sequential process steps for wafer etching, and coordinates all on-chamber sub-components during wafer processing cycles.
Multi-channel signal acquisition and closed-loop control It collects analog and digital feedback signals from pressure transducers, temperature sensors, gas flow controllers, plasma monitors and limit switches. It calculates real-time parameter deviations and outputs control signals to stabilize etch environment.www.plcva.com
Internal bus communication coordination It communicates bidirectionally with system HMI, host controller, RF power modules, motion boards and I/O sub-boards via proprietary industrial bus. It synchronizes command transmission and status feedback across the whole chamber subsystem.
Safety interlock and fault monitoring Continuously monitors emergency stop, chamber door lock, vacuum status and gas safety interlock signals. It triggers protection actions such as RF cutoff and gas shutdown once abnormal conditions occur. It records fault events and uploads alarm information for equipment diagnosis.plcva.com
Process data logging and traceability support Captures runtime process parameters during wafer processing, stores local logs, and transmits data to fab host system. It supports wafer lot traceability, recipe audit and equipment performance analysis.
