CVD Process Chamber Solution – Applied Materials 0021-34728 Blocker | HHVB82 Series
The Applied Materials 0021-34728 Blocker (cross-reference: HHVB82 / 715-21274-008) is a precision-engineered chamber component designed for use in Applied Materials CVD and PVD deposition systems. This blocker plate controls gas flow distribution and shields critical chamber surfaces during thin-film deposition processes, directly impacting film uniformity and chamber longevity.
Where This Product Is Used
- Semiconductor Wafer Fabrication (Fab) — Installed in Applied Materials CVD/PVD process chambers for 200 mm and 300 mm wafer production lines.
- Thin-Film Deposition Systems — Used in PECVD, LPCVD, and physical vapor deposition chambers where precise gas flow control is critical.
- Display Panel Manufacturing — Applied in flat-panel display (FPD) deposition equipment requiring high-uniformity coating.
- Solar Cell Production — Deployed in photovoltaic thin-film deposition lines using Applied Materials platforms.
- Advanced Packaging & MEMS — Supports deposition steps in advanced IC packaging and MEMS device fabrication.

Application-Specific FAQ
Q: Is 0021-34728 compatible with both 200 mm and 300 mm Applied Materials chambers?
A: Compatibility depends on the specific chamber model. Please share your chamber part number or system model (e.g., Centura, Producer) and we will confirm fitment before shipment.
Q: What is the difference between 0021-34728, HHVB82, and 715-21274-008?
A: These are cross-reference part numbers for the same component used across different Applied Materials documentation revisions and procurement systems. All three refer to the same blocker assembly.
Q: Do you offer refurbished or reconditioned units?
A: Yes. Refurbished units are available at reduced cost with full dimensional inspection reports. Specify “refurbished” when requesting a quote.
Q: Can you supply a full PM kit including this blocker?
A: Yes. We can assemble complete preventive maintenance kits tailored to your chamber model. Contact us with your PM BOM for a consolidated quote.
Q: What is your minimum order quantity (MOQ)?
A: MOQ is 1 piece. Volume discounts apply for orders of 5+ units.
