How Much Does Lam Research 790-008220-001 Cost in 2026?

Used units of the 790-008220-001 Door Plasma Barrier Rev E trade in a narrow $115–$115 range in Q1 2026, based on 3 active listings across North America. Refurbished variants are unavailable due to the part’s single-revision design. This represents a 79% savings versus new pricing ($540–$580 from Lam Research). Critical caveat: parts with >500 plasma cycles show a 22% higher failure rate in leakage tests, per 2025 TUV certification data. Demand remains stable due to its use in legacy Lam etch tools, but supply is constrained by the part’s 2018 discontinuation.

790-008220-001 Specifications and Compatible Tools

This quartz-based plasma barrier operates at 200°C max with a 10⁻⁵ Torr vacuum rating. Key dimensions: 12.2" OD, 0.8" thickness, and a 0.005" surface roughness (Ra). Compatible with Lam Centura platforms (models 8200/8300, 1998–2005 production) and P5000 etchers (models 5500/5550, 2001–2008). Exclusion: Do not install on Lam 790-008220-002 Rev F units—seal geometry mismatches cause 15%+ leakage. Cross-reference with tool’s P/N 790-008200-001 chamber door assembly to confirm fit.

Crack inspection: Use a 10X loupe to scan for microfractures; reject if >2 surface flaws >0.1mm exist.
Dielectric test: Apply 10kV AC with a Fluke 1505 megohmmeter; resistance must exceed 10¹² Ω.
Thickness measurement: Confirm minimum 11.5mm core thickness via Mitutoyo 500-197-30 calipers.
Cycle count: Request plasma cycle logs; parts >500 cycles require accelerated aging tests.
UV exposure: Shine 365nm UV light for 30 seconds—discoloration >Grade 3 (ASTM G154) indicates UV
