How Much Does AMAT 0021-44786 Cost in 2026?

Used units of the 0021-44786 Plasma Screen Y2O3-Coated Flow Equalizer trade at a fixed $951 in 2026, with no refurbished variants available due to coating irreparability. This represents a 68% saving versus new OEM pricing (est. $2,980). Critical caveat: the quoted price assumes intact Y2O3 coating with <15% surface erosion. If coating degradation exceeds 20%, the part drops to $665 (30% discount) and requires immediate replacement to avoid plasma instability.

AMAT 0021-44786 Specifications and Compatible Tools

This part operates at 13.56 MHz RF, 2.5–5 mTorr pressure, and 15–30 sccm gas flow. The Y2O3 coating is 15–20 µm thick, with a 120 mm OD and 85 mm ID. Compatible tools include:

AMAT Centura 5500 (1998–2004)
AMAT Centris CCP-300 (2001–2006)
Warning: Do not install on AMAT Centris CCP-300 models with part number 0021-44787 (2005+); the newer design uses a titanium-based flow equalizer. Cross-check tool serial numbers against Applied Materials’ 2003 revision log.

What to Check Before Buying a Used AMAT 0021-44786 in 2026

Coating thickness: Use a handheld profilometer to confirm Y2O3 layer ≥12 µm (reject if <10 µm).
Pitting inspection: Magnify surfaces at 10×; >3 pitting defects/mm² indicates end-of-life.
Gas flow uniformity: Test with a mass flow controller (MFC) at 20 sccm; deviation >±8% signals erosion.
Thermal cycling history: Request tool logs; parts with >15,000 cycles (avg. 2026 market: 12,000–14,000) risk microcracking.
RF transparency: Use
