Contact [email protected] with your chamber serial number for exact cross-reference confirmation.
Why Choose the Original Model
- Process Repeatability: OEM-spec sensor calibration ensures consistent shutter timing, directly impacting deposition uniformity and film thickness control.
- Chamber Qualification: Using the original P/N avoids re-qualification cycles required when substituting non-OEM components.
- Integrated Sensor Reliability: Factory-integrated sensor eliminates field-assembly tolerances that can cause false position signals.
- Warranty & Traceability: OEM parts carry full traceability documentation, essential for ISO-certified fabs.
Typical Applications
- Applied Materials Endura PVD systems — Al, Ti, TiN, Cu target chambers
- Applied Materials Centura CVD platforms — process isolation shutter applications
- Semiconductor wafer fabrication lines (200 mm / 300 mm)
- Flat panel display (FPD) deposition equipment
- R&D and pilot-line PVD tools requiring precision shutter control
System Compatibility
| System Platform | Chamber Type | Compatibility |
|---|---|---|
| Endura 200 / 300 | PVD Metal | Confirmed |
| Centura 200 | CVD Dielectric | Verify BOM revision |
| Producer GT | CVD | Not applicable |
| Custom OEM Builds | Various | Contact us to verify |
Selection Guide
- Identify your chamber platform — Endura or Centura? Check the chamber nameplate or service manual.
- Locate your BOM P/N — Search for 0021-XXXXX in your chamber spare parts list. If 0021-70379 appears, this is your part.
- Check sub-assembly reference — If your BOM lists KLB-1SII, N2200, or USC-881, this assembly is the correct match.
- Determine condition requirement — New OEM for critical process chambers; refurbished for non-critical or backup tools.
- Confirm sensor harness compatibility — Verify connector type matches your chamber wiring harness before installation.

Replacement & Compatibility FAQ
Q: Can I use a refurbished SM312CV2 in a production chamber?
A: Yes, provided the unit has been cleaned, inspected, and comes with a test report. Many fabs use certified refurbished shutters in non-critical or backup chambers to reduce cost.
Q: What is the difference between 0021-70379 and 0021-70379-001?
A: The suffix typically denotes a minor engineering change order (ECO). Functionally they are often interchangeable, but confirm with your process engineer or AMAT field service representative.
Q: Is the sensor replaceable separately?
A: The USC-881 sensor kit may be available as a standalone item. Contact us with your specific sensor connector and signal type for availability.
Q: What is the lead time for new OEM stock?
A: New OEM units typically ship within 3–10 business days depending on regional stock. Refurbished units are often available for same-week dispatch.
Q: Do you provide export documentation for international shipments?
A: Yes. We provide commercial invoice, packing list, CoC, and can assist with ECCN/HTS classification for customs clearance.
