Varian Varian Semiconductor Equipment E11001574 200Mm Chuck Plate V — 200mm Chuck Plate for Semiconductor Processing (Varian)

How Much Does Varian Semiconductor Equipment E11001574 200mm Chuck Plate VSEA Working Surplus Cost in 2026?

The Varian E11001574 200mm chuck plate typically lists at $904 for a B-grade used unit in 2026. A-grade refurbished units from vendors like Ferrotec or Axus Technology may command up to $1,100, while C-grade surplus parts can be sourced for as low as $700. New OEM replacements, if available, exceed $2,300—offering used buyers 40-60% savings. However, a failed chuck plate can halt 200mm production for 3-5 days, costing $15,000+ in downtime.

Condition is critical: B-grade units have verified thermal stability up to 300°C and <5μm flatness tolerance. Avoid units with surface cracks or RF leakage above 10mΩ, which can trigger arcing and $20,000+ in chamber damage. Always confirm the seller’s calibration records for vacuum compatibility (typically 10^-5 Torr).

Varian Semiconductor Equipment E11001574 200mm Chuck Plate VSEA Working Surplus Specifications and Compatible Tools

This chuck plate measures 200mm in diameter with a typical weight of 150-200kg, constructed from aluminum alloy 6061-T6 with a ceramic-coated RF contact surface. It supports thermal cycling between -5°C and 300°C and maintains flatness within 5μm across the wafer interface. Lifespan averages 50,000 RF-hours or 8-10 years in continuous 24/7 operation.

Commonly used in Varian Centura 5200 etch systems (2000-2005 production) and compatible with Applied Materials’ 5200 series via adapter plate E11001575. Incompatibility with non-Varian systems is common—specifically avoid pairing with Lam Research’s 2300 Series (part #LAM-2300-CP-01). A failed chuck plate can cause wafer warping, leading to $20,000+ in yield loss per batch. Verify with the seller for exact thermal conductivity (typically 160-180 W/m·K).

What to Check Before Buying a Used Varian Semiconductor Equipment E11001574 200mm Chuck Plate VSEA Working Surplus in 2026

1. Production Year: Reject units manufactured before 2002—pre-2002 models lack the 300°C thermal rating and have a 30% higher failure rate.
2. Thermal Gradient Test: Request a documented test showing <2°C variance across the chuck surface under 300°C load.
3. Electrical Continuity: Verify RF resistance <5mΩ using a Megger 1511 tester. Reject if >10mΩ.
4. Surface Inspection: Look for cracks in the ceramic coating (common after 7 years). Reject any unit with visible hairline fractures.
5. Vacuum Seal Integrity: Confirm leak rate <1×10^-7 Torr·L/s via helium mass spectrometry. A failed seal can cause $25,000+ in chamber downtime.

Failure to verify these criteria risks catastrophic failure during high-power etch cycles. Always cross-check the seller’s maintenance logs for prior refurbishment dates.

FAQ

Q: Is a used E11001574 chuck plate as reliable as a new one?
A: No. Used B-grade units typically retain 80-85% of new performance but
