How Much Does Applied Materials 0021-40940 Cost in 2026?

Used units for 0021-40940 (Centura DPS Alumina Ring) range from $12,000 to $18,000 in 2026, depending on erosion depth and service history. Refurbished variants (with <0.2mm material loss and full RF recalibration) cost $8,500 to $14,000. This represents 40–60% savings vs. Applied Materials’ 2026 new pricing ($22,000–$30,000). Critical caveat: rings with >0.3mm erosion near the RF coupling slot will fail oxide etch uniformity specs (<±3% required), even after resurfacing. Always verify service logs for plasma arcing incidents in the prior 12 months.

Applied Materials 0021-40940 Specifications and Compatible Tools

The 0021-40940 is a 300mm alumina (99.5% Al₂O₃) confinement ring with a 25.4mm height and 1.5mm wall thickness. Key specs: dielectric strength 6kV/mm, thermal shock resistance up to 350°C, and RF transparency at 13.56MHz. Compatible with:

  • Applied Materials Centura DPS 8200 (1998–2005)
  • Centura DPS Plus 8220 (2001–2008)
  • Endura DPS 8900 (2003–2007)
    Exclusion: Not compatible with Axcelis 12-6543-01 chambers due to mismatched RF coupling slot geometry. Verify chamber serial numbers ending in “X-44” or “X-45” for fit.

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

  1. Erosion depth: Use a Mitutoyo 500-196-30 micrometer. Reject if radial wear exceeds 0.3mm or slot depth drops below 0.8mm.
  2. Alumina integrity: Test with a 5MHz ultrasonic flaw detector. Reject if >2% porosity or subsurface cracks >1.5mm.
  3. RF continuity: Measure resistance across
