Gas sticks and welds, signed at the joint
Cleanroom crews run valve manifold box leak checks, pigtail swaps, and SEMI F81 weld acceptance on offline intelliINSPECT wizards, each result signed against the tool the line feeds.
Industry
A pinhole in a silane line can clear the whole fab. Prove every joint before the alarm does.
Fab facilities and EHS teams use intelliSPEC to keep every gas stick, weld, and scrubber on a signed inspection record, from the sub-fab to the cleanroom, on one standard across US, EU, and Asia sites.

Four systems that end the run when they fail.
Gas delivery, high-purity piping, abatement, and the permits that let anyone touch them. One module owns each job, and every result lands on the same record.

Where the fab is fragile
Four systems that end the run when they fail.
Gas delivery, high-purity piping, abatement, and the permits that let anyone touch them. One module owns each job, and every result lands on the same record.
Exhaust and abatement, measured not guessed
intelliNDT turns UT thickness readings on acid-exhaust ducting and scrubber shells into corrosion rates and remaining life, so replacement is scheduled on the data, not on the failure.
HPM permits with a spine
Hot work near a silane header, LOTO on a chemical dispense system. intelliCOMPLY routes every permit and JSA to an owner and closes it with proof the AHJ can read against NFPA 318 and IFC hazardous production material controls.
The annual power-down, gated
intelliTURN holds facility shutdown scope, gas-system tie-ins, and restart gates in one plan, so the fab comes back up on schedule with every system verified, not vouched for.
One record, gowned in
Follow one silane stick from the sub-fab to the auditor.
The record moves with the work. Nothing is retyped, nothing waits for the office.
Capture at the stick
A technician gowns in, opens the VMB checklist offline, logs the helium leak reading and fitting torque, and signs at the panel. No paper leaves the cleanroom.
The verdict, recomputed
The reading syncs and the platform re-runs the math. A drift past tolerance flags the stick, opens a corrective action with an owner and a due date, and resets the inspection interval to SEMI F-series practice.
Proof on demand
When the AHJ or the insurer asks, the fab exports every check, verdict, and closeout on that line as one query, mapped to SEMI S2 and NFPA 318, for any site in the network.
Proof path
The AHJ walkthrough is already on the calendar.
Bring one fab's gas-system routine and we will walk the record from the stick to the signature.
01
Weld visual acceptance on high-purity gas and UPW lines captured to SEMI F81 in intelliINSPECT, offline in the cleanroom.
02
Acid-exhaust and abatement corrosion rate and remaining life computed in intelliNDT, with intervals reset on each reading.
03
HPM permits, hot work, and LOTO threaded into one NFPA 318 and IFC-ready audit trail in intelliCOMPLY.
Answers
Semiconductor Fabs questions
Does intelliSPEC support SEMI S2 and S8 safety inspections?
Yes. Gas-delivery leak checks, interlock verification, and abatement testing are captured as structured records against SEMI S2 equipment safety and SEMI S8 criteria, held against the specific tool, with lapses surfaced before an audit finds them.
How do valve manifold box and gas stick inspections work in intelliSPEC?
Crews run VMB checklists on intelliINSPECT offline in the cleanroom, logging leak readings, purge checks, and pigtail replacement to SEMI F-series practice. Each stick carries its own history, tied to the tool it feeds.
Can it document orbital weld inspection on high-purity piping?
Yes. Visual weld acceptance is captured to SEMI F81 criteria in intelliINSPECT, with photos, inspector signature, and timestamp on each joint, so the weld map survives the contractor who made it.
What software do semiconductor fabs use for hazardous production material compliance?
Fabs use intelliCOMPLY to route HPM permits, hot work, JSAs, and LOTO to owners with closeout proof, building the audit trail that NFPA 318 and IFC hazardous material chapters expect.
Does it track corrosion on fab exhaust and abatement systems?
Yes. intelliNDT computes corrosion rate and remaining life from UT thickness readings on acid-exhaust ducting, scrubber shells, and burn-box headers, so replacement lands on a schedule instead of an alarm.
Does intelliSPEC work offline inside a cleanroom?
Yes. Inspections capture fully offline on a gowned-in tablet and sync when the technician exits, so ISO 14644 protocol and dead zones in the sub-fab never break the record.
Can it manage a fab facility shutdown or annual power-down?
Yes. intelliTURN tracks shutdown scope, gas-system tie-ins, and restart readiness gates in one plan, so every system is verified with a signature before the fab powers back up.
