Varian Varian Semiconductor Equipment E17039590 Graphite Shield Vse — [SHORT_DESCRIPTION] (Varian)

How Much Does Varian Semiconductor Equipment E17039590 Graphite Shield VSEA New Surplus Cost in 2026?

The Varian E17039590 Graphite Shield VSEA New Surplus is priced at $701 in 2026, reflecting a "B" condition grade with minor surface oxidation. Refurbished units from vendors like Ferrotec and Axus Technology typically range between $650–$750, while OEM new units (if available) would cost $1,168–$1,752. This represents 40–60% savings over new, critical for budget-conscious fabs facing downtime costs of $5,000/hour during equipment delays. However, buyers must verify the unit’s thermal shock resistance rating (typically 12–15 cycles/min) and ensure it hasn’t exceeded 10,000 operational hours. A failed shield can cause plasma instability, leading to $10,000/day in lost production. Always request a pre-shipment inspection report to avoid subpar units.

Varian Semiconductor Equipment E17039590 Graphite Shield VSEA New Surplus Specifications and Compatible Tools

This graphite shield is designed for Varian’s high-temperature plasma chambers, commonly used in 300mm wafer etching. Key specs include a 12-inch diameter, 0.5-inch thickness, and a maximum operating temperature of 1,400°C. It typically lasts 8,000–12,000 RF-hours before requiring replacement, depending on thermal cycling frequency. Compatible tools include Varian’s Centura® platforms (models 8920, 8940) from 2005–2012. Incompatibility warnings apply to E17039591 variants, which have a 13-inch diameter and may cause misalignment. A mismatched shield can lead to arcing, damaging adjacent components like the matching network and costing $15,000 in repairs. Verify with the seller that the unit is rated for 1.5–2.0 Torr vacuum conditions and has no microcracks visible under 10x magnification.

What to Check Before Buying a Used Varian Semiconductor Equipment E17039590 Graphite Shield VSEA New Surplus in 2026

1. Production Year: Reject units manufactured before 2010 due to outdated graphite composites prone to delamination.
2. Thermal Shock Testing: Request a documented test at 1,200°C to 25°C in 30 seconds. Failure indicates structural weakness.
3. Surface Inspection: Use a 20x loupe to check for cracks wider than 0.1mm or pitting deeper than 0.2mm.
4. Dimensional Tolerance: Measure with a digital caliper; deviations beyond ±0.005 inches will cause sealing issues.
5. Coating Integrity: Verify the anti-reflective coating (if present) is intact using a UV-Vis spectrophotometer.

A defective shield can cause plasma chamber contamination, requiring $20,000 in cleaning and downtime. Always cross-reference the seller’s data with Varian’s 2008 service bulletin on E17039590 material upgrades.

FAQ
