Semiconductor FMEA software

Every tool-down makes the whole tool fleet smarter.

Tool-down events, PM findings and engineering notes are checked against your tool-family FMEA. The best fix on day shift becomes the default on night shift.

How it works, every week

Your tool-family FMEAs keep themselves current.

New evidence, matched

Tool-down events, PM findings and notes checked against your FMEAs as they arrive.

One short list a week

Your equipment engineer gets a short list, not a re-review.

Approve once, it reaches everything

Each approved change reaches every chamber of the same configuration.

Nothing changes without your engineer's approval. Every change versioned and sourced.

Where Tacit AI makes the difference

Every proven fix, found in seconds, applied to every tool.

Retrieve known solutions with evidence

Search manuals, SOPs and notes by symptom, chamber or configuration. Every answer cited.

Establish equipment-risk baselines

Tool-family FMEA built from your evidence. Owners approve every change.

Compare like tools without erasing context

Repeat evidence across comparable tools. Reuse only after an owner confirms.

Prioritize fab investigations by availability and WIP impact

Tool events ranked by downtime, WIP held and yield exposure.

Govern knowledge and changes

Role-based approval, citations and controlled export, built in.

See which data gaps would invalidate your analysis

Event data checked first, so every pattern is one you can trust.

Economic and technical owners

For leaders who own availability, excursion response and knowledge continuity.

Equipment, process and yield engineers sharing fixes across shifts and sites.

Mature fabs

Recover approved knowledge from fragmented history

Records linked to recurring symptoms. Engineers decide which fixes apply.

New tools and ramps

Create a governed starting baseline

A governed baseline from OEM documents before history builds.

Standards supported

Built to the methods you already use.

Scoped to your workflow and selected editions, including SEMI S2 for equipment environmental, health and safety.

SEMI E10

SEMI E58

SEMI S2

IEC 60812

How you get there

One tool family this quarter. The whole fab next year.

Start where the evidence is richest. Each system after starts ahead.

MONTH 1

Start with your tool-family FMEA

Bring one tool family's tool-down history and PM records. First draft in under 3 weeks.

MONTH 3

Tool-downs and PM findings flow in weekly

Your equipment engineer approves each change once. Every matching chamber updates.

YEAR 1

Every tool family on one standard

The list shrinks every month. The next qualification is just another week.

Questions

Semiconductor evidence questions, answered.

Can it build an equipment FMEA for a tool family?

Yes. Tacit AI builds a source-linked FMEA per tool family from OEM manuals, SOPs, work orders, fault logs and engineering notes, with chamber, module, recipe and configuration context preserved. Tool, process, EHS and reliability owners set scope, ratings, controls and procedure changes and sign off.

How does it use SEMI E10 and SEMI S2?

As terminology and structure. Equipment states, downtime categories, and RAM metrics follow SEMI E10 where the fab selects it, so outputs land in the vocabulary your OEE and availability reporting already uses. SEMI S2 is EHS guidance for equipment and is referenced for context only. Tacit AI organizes your data to these standards.

How are equipment events connected to yield?

On one timeline. In Phase 1, equipment, process, excursion, qualification and yield data are aligned in time. Every association shows its matching rules, sample size, lag, missing data, recipe and product mix, upstream and downstream effects and confounders. No black-box correlations.

Can it connect to SPC, FDC, CMMS, or MES data?

Yes. Integrations are scoped against interfaces, volume, timestamp and equipment-identity quality, data ownership, security, validation and system-of-record controls. Phase 1 starts from a controlled extract, with production integration after.

Does Tacit AI score technicians or process engineers?

This workflow evaluates evidence and documentation, not employee competence or performance. Any workforce analytics would require a separate, explicitly governed use case with legal, privacy, labor, and human-review controls.
