4. Working Principle
Power‑On Initialization and Overall Self‑Test
Once powered by regulated equipment supply, the board automatically completes initialization. It sequentially performs hardware chip self‑test, signal channel inspection, communication protocol loading, original process parameter import, interlock logic verification and port function calibration. It comprehensively detects hidden risks including hardware faults, channel anomalies, parameter disorder, communication link failures and wiring abnormalities. Upon passing self‑test, handshake communication is established with the equipment main control system, chamber sensors and front‑end actuators, and the board enters normal process monitoring and control status.
Multi‑Channel Process Signal Acquisition and Precision Preprocessing
During equipment operation, the board simultaneously collects core sensing signals including chamber vacuum level, operating temperature, process gas flow rate, RF power and chamber pressure. Built‑in multi‑stage digital filtering, electromagnetic noise elimination, automatic temperature drift compensation and linear calibration algorithms conduct noise reduction, waveform shaping, error correction and range conversion for raw weak and fluctuating signals. Signal distortion caused by high‑frequency electromagnetic interference and ambient temperature variation is filtered out to output accurate, stable and standardized process data, providing reliable foundation for closed‑loop process control.
Closed‑Loop Calculation and Precision Regulation of Process Parameters
Based on preconfigured process recipes and control logic, the board continuously compares measured process parameters against system setpoints, dynamically calculates deviation values and outputs precise regulating drive signals. It realizes real‑time linkage with actuators such as gas control valves, temperature control units, RF power supplies and vacuum modules to dynamically adjust operating parameters, accurately meeting temperature, pressure, flow and power requirements for etching, deposition and other processes. Process parameters remain constant throughout operation to avoid process deviation induced by parameter fluctuation and ensure consistency and stability of wafer manufacturing.
Safety Interlock Protection and Abnormality Latching Control
All process parameters and equipment operating status are monitored continuously during operation. Relying on embedded hardware interlock logic, overrange parameters and abnormal conditions are judged in real time. When faults such as over temperature, pressure overrange, abnormal flow, vacuum leakage or signal loss occur, a safety protection mechanism is activated within milliseconds. Current process status is latched, abnormal actuators are shut down and equipment alarms are triggered to prevent wafer scrap, equipment damage and chamber contamination caused by fault escalation, safeguarding equipment and process safety.
Data Exchange and Fault Trace Logging
Via proprietary original equipment bus, real‑time process parameters, board operating status, equipment working conditions and channel status are uploaded to the upper main control system. Meanwhile, process recipes, start/stop commands and parameter calibration instructions issued by the main controller are received, parsed and executed accurately. Operation logs, process parameter curves, fault alarm timestamps and error codes are automatically recorded throughout operation, providing complete data support for process optimization, fault tracing, equipment maintenance and process review.
5. Common Faults and Troubleshooting
Phenomenon: No response after power‑on; board unrecognized by equipment; process module offlinePossible Causes
① Abnormal equipment power supply, unstable voltage, poor contact in power circuit or excessive power ripple;
② Oxidation of board gold fingers, dust accumulation in slots resulting in poor contact;
③ Lost, crashed firmware or firmware version incompatible with equipment system;
④ Long‑term aging, damaged core chips or internal hardware circuit failure.
Solutions
Shut down equipment and fully discharge power. Inspect supply voltage and circuit continuity, check tightness of power terminals and wiring. Remove the board, clean gold fingers and slot dust/oxide layers in a clean environment, then firmly reinsert the board. Re‑flash compatible original firmware matching the equipment system version and restore factory default process parameters. If no response persists with normal power supply, contact and firmware, hardware damage is confirmed; replace with original spare part 0190‑80781.
Phenomenon: Fluctuating and drifting process parameters, unstable process, reduced wafer yieldPossible Causes
① Severe interference on signal channels, poor shielding & grounding leading to distorted sensor signals;
② Long‑term parameter drift without regular process calibration;
③ Aging signal acquisition channels with degraded sampling precision;
④ Electromagnetic interference from adjacent RF and variable frequency equipment causing abnormal sampling.
Solutions
Inspect signal cable shielding and grounding system, improve anti‑interference grounding measures to mitigate electromagnetic noise. Re‑calibrate temperature, pressure, flow and other process parameters via the equipment host to correct drift. Troubleshoot abnormal signal channels and optimize channel configuration. If faults remain after calibration and interference improvement, degradation of board acquisition performance is confirmed; replace the board.
Phenomenon: Frequent process alarms, false interlock triggering and repeated process interruptionPossible Causes
① Improper threshold setting for interlock parameters and drifted process protection values;
② Transient signal interference causing misjudgment and false alarms;
③ Abnormal and disordered board interlock logic program;
④ Channel circuit failure leading to abnormal signal output.
Solutions
Verify process interlock thresholds and protection parameters, correct incorrect and drifted configurations. Optimize equipment electromagnetic shielding to eliminate transient signal interference. Reboot the board to reset programs and restore factory standard interlock logic and process settings. Test interlock functions under simulated process conditions to identify logic defects. Replace the board promptly if faults persist to guarantee stable production.
Phenomenon: Board communication interruption; main control system fails to read process data; command transmission disabledPossible Causes
① Loose bus communication cables, oxidized interfaces or damaged wiring;
② Misconfigured board communication parameters and mismatched bus protocols;
③ Bus network conflict and duplicate device addresses;
④ Aging communication chip and damaged communication circuit on the board.
Solutions
Fully inspect communication bus cables and connectors, clean oxidized contacts, fasten loose connections and replace damaged cables. Verify and unify board communication parameters, bus protocols and network configurations to eliminate address conflicts. Reboot equipment bus and board programs to re‑establish system handshake. If communication still fails with correct wiring and parameters, communication circuit failure is confirmed; replace original board.
Phenomenon: Excessively high board temperature, equipment lagging, frequent restart and error reportingPossible Causes
① Heavy dust accumulation in cabinet and blocked air duct resulting in poor heat dissipation;
② Abnormal power consumption caused by full‑load chip operation under prolonged heavy process computation;
③ Severe power supply fluctuation and power noise;
④ Unstable firmware and version compatibility issues.
Solutions
After shutdown, thoroughly clean cabinet air ducts and dust on the board surface to improve ventilation and stabilize cabinet operating temperature. Optimize power supply quality, stabilize voltage and suppress power interference. Reduce redundant program tasks and flash stable original compatible firmware. Replace the board in advance if failures recur due to component aging, avoiding production downtime and wafer scrap risks.
Phenomenon: No data at certain process points, no actuator response, partial process out of controlPossible Causes
① Damaged corresponding signal channels or disabled/locked channel parameters;
② Signal interruption caused by faulty front‑end sensors or actuators;
③ Board channel protection activated and function self‑locked;
④ Partial circuit failure leading to single‑channel malfunction.
Solutions
Inspect sensors and actuators at corresponding positions and replace defective front‑end components. Check channel configuration parameters, release fault protection lock and reactivate disabled channels. Reboot the board for initialization and test signal acquisition and command output of related channels. If no signal is obtained with normal front‑end equipment and parameters, partial channel damage on the board is confirmed; replace original board.
