Used Entegris 300mm FOUP: Fit and Cleanliness Checks

Evaluate used Entegris FOUPs by the exact model and the requirements of your wafer-handling process. Request product labels, condition photos, previous-use history, and a documented acceptance plan before placing an order.

Match the FOUP model, not just the wafer diameter

Entegris lists A300 FOUPs in 25- or 13-capacity designs for 300 mm wafer processing. Specify the required capacity and exact product variant rather than assuming every Entegris 300mm FOUP has the same configuration.

Record the full part number, revision if identified, body and door labels, wafer dimensions and thickness requirements, and any required purge or identification features. Have your equipment engineer review the proposed FOUP against the load-port documentation and your approved carrier specification.

What to request from the seller

Ask for individual or traceable lot identification, photos of wafer-contact areas and the door, records of repairs or replaced parts, previous process exposure where known, and cleaning and packaging documentation. Require the seller to identify unknown history rather than describe it as verified clean.

If buying a lot, agree how each pod will be inspected or how a sampling plan will be approved. Keep unidentified or undocumented units out of the accepted lot until the responsible reviewer resolves them.

Define fit and cleanliness acceptance criteria

1. Identity and condition: Reconcile labels and quoted models; inspect the shell, door, wafer supports, and other specified features for damage or missing parts.
2. Mechanical fit: Have the responsible engineer define a controlled fit and door-operation check on the intended interface using approved test materials.
3. Cleanliness: Require a cleaning process and measurement plan approved for your use, with documented methods, limits, results, and traceability.
4. Configured features: Include any required purge or identification functions in the agreed demonstration.
5. Packaging and remedies: Specify final handling, packaging, labeling, and the outcome for failed or untraceable units.

Use site-approved procedures; do not introduce an improvised contamination test or adopt numerical particle or opening-force limits without the relevant specification.

For procurement planning, review the FOUP buying guide. Compare the Entegris wafer carrier page and FOUP pod page as separate inquiries; these links do not establish interchangeability.

Request a model-specific lot quote

Request a FOUP quote with the exact part number or label photos, required quantity, wafer and load-port requirements, cleaning acceptance criteria, and destination. Ask for an itemized quote tied to the offered lot and its inspection records.
