How Much Does Lam Research 716-443083-004 Cost in 2026?

Used units for 716-443083-004 typically range from $12,000 to $15,000, while refurbished variants command $18,000 to $20,000. New OEM parts exceed $35,000, offering 40–50% savings with used/refurbished options. However, parts from systems with >50,000 process cycles show 30% higher defect rates in plasma uniformity tests. Always verify the part’s installation history—units from high-duty-cycle tools (e.g., 24/7 operations) require closer inspection for thermal fatigue.

716-443083-004 Specifications and Compatible Tools

This aluminum-nitride-coated confinement ring operates at max 350°C and 1–5 mTorr pressure ranges. Key dimensions: Ø280mm x H65mm with 0.05mm surface roughness (Ra). Compatible with Lam’s Plasmalab Series 100 (2012–2018), Symphony Etch Platform (2015–2020), and Centura DSiE (2010–2016). Exclusion: Not compatible with 790-xxx models due to divergent port-thread profiles (check PN 716-443083-002 for alternatives). Cross-reference tool’s chamber ID tag for validation.

What to Check Before Buying a Used 716-443083-004 in 2026

Erosion depth: Use a digital micrometer to measure wall thickness. Reject if <0.8mm (original spec: 1.2mm).
Crack detection: Perform eddy current testing at 5MHz; reject parts with >2mm surface flaws.
Gas flow deviation: Test with a mass flow controller (MFC-5000); deviation must stay within ±5% of rated flow.
Thermal cycling history: Reject parts with >8,000 cycles (use Lam’s CycleLog™ tooling ID scan).
Plasma uniformity: Run a 30-minute test at 500W RF; non-uniformity >12% invalidates part.
