How Much Does AMAT 0021-40940 Confinement Ring Cost in 2026?

Used units range from $12,000–$18,000 in 2026, depending on chamber cycle count (10k–25k cycles). Refurbished variants (recoated with Al₂O₃) cost $8,500–$14,000, saving 40–60% vs. new ($35,000–$45,000). Price variance hinges on edge erosion: rings with >1.2mm radial wear require recoating, adding $2,500–$4,000. Avoid units with >3mm vertical deformation—these fail Centura’s 0.5mm flatness spec.

What to Check Before Buying a Used AMAT 0021-40940 in 2026

Ceramic coating thickness: Use a micrometer; <0.15mm Al₂O₃ layer requires recoating.
Radial wear: Measure OD with a digital caliper; >1.2mm erosion reduces plasma containment.
Crack inspection: Use a 10X borescope for microfractures in ceramic; reject any >0.05mm gaps.
Chamber cycle count: Units >30k cycles show accelerated erosion; verify via OEM logbook or PLC data.
Plasma uniformity test: Run a dummy wafer etch; >15% edge uniformity deviation indicates misalignment.
