How Much Does Lam Research 716-011830-008 Cost in 2026?

Used units for 716-011830-008 alumina focus rings typically range from $1,200–$1,800 in 2026, while refurbished variants (with ceramic resurfacing) cost $2,500–$3,000. New OEM parts exceed $6,500, offering ~75% savings with used options. Critical caveat: erosion depth above 0.1mm on the wafer contact surface correlates with plasma uniformity degradation >15%, invalidating process specs. Always verify part history—units from tools with >1,200 process cycles show 3x higher failure rates in edge plasma stability tests.

716-011830-008 Specifications and Compatible Tools

This alumina (99.5% Al₂O₃) focus ring operates at 1.5kV max, 500W RF power, and 13.56MHz frequency. Dimensions: OD 280mm, ID 200mm, thickness 15mm. Compatible with Lam Research Centura platforms (models 8200/8220, 2008–2015), PRODUCER 5000 series (models 5500/5700, 2010–2017), and Symphony 9400 (2012–2020). Exclusion: Do not install on Lam 7900 platforms (part 716-011830-009)—incompatible clamping force profile causes microcracking. Cross-check tool’s RF matching network specs; mismatched impedance (>50Ω) risks arcing.

What to Check Before Buying a Used 716-011830-008 in 2026

Erosion depth: Use a digital micrometer to measure wafer-contact surface. Reject if erosion exceeds 0.12mm (spec limit).
Dielectric strength: Apply 2kV AC for 1 minute using a megohmmeter. Leakage >10µA invalidates insulation integrity.
Crack propagation: Inspect under UV light for microcracks. Any flaw >0.2mm length fails due to plasma arcing risk.
Surface finish: Profile with a 3D stylus instrument. Ra >1.6µm indicates excessive wear, degrading plasma uniformity.
Cycle count: Request tool logs. Avoid parts with >1,500 etch cycles—edge wear rates accelerate 40% post-threshold.
