Continuous low-noise vibration telemetry, wideband acoustic diagnostics, and OPC UA / EDA edge intelligence for cleanroom facilities, plasma etch and deposition chambers, mass flow controllers, turbomolecular vacuum skids, and automated material handling systems (AMHS). Designed for use on SEMI S2-assessed tools, ISO 14644-1 Class 3–4 cleanrooms, and Generic Vibration Criteria (VC-B to VC-G).
Acoustic transient analysis and micro-vibration tracking across plasma etch, ALD, and CVD chambers, monitoring electrostatic chuck integrity and slit valves.
Real-time envelope demodulation and wideband acoustic sensing detect turbomolecular bearing touchdown, chamber plasma strike transients, and MFC micro-leaks to support early detection and planned maintenance.
Deterministic fieldbus bridges stream spectral indicators and threshold alarms directly into tool controllers, MES schedulers, and facility sub-fab SCADA systems.
Dry plasma etching (RIE, ICP-RIE) and thin-film deposition tools (ALD, PECVD, PVD) operate under severe RF electromagnetic fields, aggressive process chemistries, and cyclic thermal vacuum dynamics. Acoustic sensor nodes mounted to outer chamber walls monitor mechanical transients during slit-valve actuation, electrostatic chuck (ESC) backside helium cooling flow stability, and RF matchbox capacitor tuning harmonics. Wideband acoustic tracking captures abnormal plasma strike transients and ESC delamination risks to support early intervention before batch yield degradation.
Semiconductor gas distribution systems route toxic, pyrophoric, and corrosive precursor gases (including SiH₄, NF₃, WF₆, and Cl₂) through ultra-high-purity (UHP) orbital-welded gas sticks and mass flow controllers. Subtle piezo or solenoid valve seat wear, thermal sensor drift, and orifice particle deposition compromise stoichiometric recipe ratios and risk hazardous gas release. Inline and surface acoustic monitoring captures high-frequency fluid turbulence and mechanical valve chatter, detecting micro-leaks and flow drift to support early warning and planned tool maintenance.
Turbomolecular vacuum pumps spinning up to ~90,000 RPM maintain high vacuum in plasma etch, CVD, and ion implantation chambers. Ceramic-bearing spall (hybrid pumps) and touchdown-bearing events (maglev pumps) can cause damage. The Mercury Z1 (Pilot Q1 2027) acoustic probe captures wideband acoustic signatures to indicate bearing degradation to support early detection and planned maintenance.
Automated Material Handling Systems (AMHS) transport front-opening unified pods (FOUPs) holding 25 delicate 300mm wafers across ceiling monorails at high speeds. Track joint misalignments, switch diverter wear, or erratic hoist deceleration can transmit destructive shock pulses, creating micro-cracks in thinned silicon. Compact IGFO-100 nodes mounted directly inside test FOUPs measure 3-axis acceleration, calculating shock response spectra (SRS) to continuously evaluate fab track geometry.
