Semiconductor Cleanroom & Sub-Fab

Semiconductor Fab Mechanical Condition Monitoring

Protect multimillion-dollar wafer lots from mechanical equipment failure: Low-noise vibration surveillance and wideband acoustic audio emission monitoring for turbomolecular vacuum pumps, Chemical Mechanical Planarization (CMP) tools, and cleanroom air handling infrastructure.

Turbomolecular Pump Early Warning & Monitoring

Turbomolecular vacuum pumps spinning at 60,000–90,000 RPM (up to 1,500 Hz shaft rotation) in the sub-fab maintain ultra-high vacuum for EUV/DUV lithography, etching, and PVD chambers. Even slight magnetic bearing unbalance or ceramic bearing spalling risks severe rotor damage. Our wideband 20 Hz – 10 kHz acoustic audio transducers track acoustic bearing-friction trends and mechanical wear indicators.

Target Equipment: High-vacuum turbopumps, roughing dry pumps, exhaust scrubbers
Hardware: Mercury Z1 (Pilot Q1 2027) (316L Stainless Steel) & IGFO-AE-100 (Target specs — Q4 2027) Motion & Acoustic Sensor
Wet Chemical Processing

CMP Tool Platen & Slurry Pump Cavitation Monitoring

Chemical Mechanical Planarization (CMP) tools require nanometre-level planarity across 300mm silicon wafers. Slurry delivery line pulsation, peristaltic pump cavitation, and platen drive spindle bearing wear cause micro-scratches that degrade wafer yield. Clamp-on acoustic and vibration monitoring of slurry pumps and manifolds (no wetted contact) tracks pump health and platen vibration.

Target Equipment: CMP polishing heads, platen drive motors, slurry delivery manifolds
Signals: Slurry Pump Cavitation Indicators, Platen Spindle 3-Axis Vibration, Surface Temp
Cleanroom Metrology

Plinth & Air Handling Surveillance

Modern lithography tools require stringent floor vibration baselines, referencing VC-E (3.12 µm/s RMS) / VC-F (1.56 µm/s RMS) criteria. Mechanical imbalance in recirculating air handling units (AHU fans), chiller water pumps, or automated overhead wafer tracks (OHT / FOUP rails) directly transfers through raised cleanroom floors. IGFO-100 tracks low-noise floor vibration trends continuously.

Guidelines: Generic Vibration Criterion Curves (VC-A through VC-F; VC-B / VC-C trending for structural plant)
Hardware: IGFO-100 Edge Node (Low-Noise AFE)
Fab Automation Protocol

Fab SCADA & MES Interoperability

Fab IT policies often restrict wireless and cloud connections. The XTR 315 gateway (Launch Q3 2027) aggregates Single Pair Ethernet (SPE) cleanroom sensor channels and publishes telemetry over OPC UA and EDA / Interface A (SEMI standards support) directly into the fab's internal MES and tool host software.

Fab Standards: SEMI EDA / Interface A support, OPC UA Companion Specs
Security: Hardware Secure Element, designed to IEC 62443-4-2 requirements for local network gateways
