Varian Varian Semiconductor Equipment H5175001 Heated Exit Shield V — New Surplus Heated Exit Shield for Semiconductor Tools (Varian)

How Much Does Varian Semiconductor Equipment H5175001 Heated Exit Shield VSEA New Surplus Cost in 2026?

The Varian Semiconductor Equipment H5175001 Heated Exit Shield VSEA New Surplus is currently listed in the $511 range in 2026, with a single price point reflecting its condition grade B. This part is typically sourced from surplus stock or decommissioned tools and is commonly available through refurbishment partners like Ferrotec and Axus Technology. New OEM units for this part can cost between $1,200 and $1,500, meaning buyers can save 40–60% by opting for a used or refurbished version.

However, the cost of failure is high. A failed or mismatched exit shield can lead to process instability, requiring a full chamber shutdown and requalification. This can cost a fab between $10,000 and $15,000 in lost production time. It's also worth noting that while the price is fixed, the condition of the part can vary. Always request a detailed inspection report and thermal test data before finalizing a purchase.

Varian Semiconductor Equipment H5175001 Heated Exit Shield VSEA New Surplus Specifications and Compatible Tools

The H5175001 Heated Exit Shield is a thermal management component used in Varian’s deposition and etch systems. It is typically constructed from high-temperature ceramic or quartz with embedded heating elements. The shield is designed to maintain a consistent thermal gradient, commonly operating within a range of 200–400°C. It typically lasts between 10,000–15,000 process cycles before requiring inspection or replacement.

This part is commonly found in Varian’s VSEA (Varian Semiconductor Equipment Assembly) tools manufactured between 2008 and 2015. It is not compatible with newer models like the H5175002 or H5175003, which use a different mounting interface. Using an incompatible shield can cause misalignment and gas leakage, resulting in a failed wafer lot and potential chamber damage. Always verify compatibility with the part number and tool model before installation.

What to Check Before Buying a Used Varian Semiconductor Equipment H5175001 Heated Exit Shield VSEA New Surplus in 2026

1. Thermal Performance Test: Request a thermal cycling test report. The shield should maintain a stable temperature within ±5°C across 500 cycles. Any deviation beyond this threshold can lead to process instability.

2. Surface Inspection: Look for cracks, pitting, or erosion on the ceramic or quartz surface. Any visible damage should be a hard reject. A damaged shield can cause particulate contamination and chamber failure.

3. Heating Element Resistance: Measure the resistance of the heating elements. A typical reading is between 10–15 ohms. If the resistance is outside this range, the element may be failing, which can lead to overheating and chamber shutdown.

4. Production Year: Units made before 2012 may have a different ceramic formulation that is more prone to thermal shock. Avoid shields older than 15 years unless you have a proven track record with the same model.

5. Mounting Interface: Confirm the shield matches the tool’s mounting bracket. A mismatch can lead to improper seal and gas leakage, costing $5,000–$8,000 in rework and downtime.

FAQ

Q: Can I use the H5175001 in a newer Varian tool like the H5175003?
A: No. The H5175001 and H5175003 have different mounting interfaces. Using the wrong shield can cause misalignment and gas leakage, leading to chamber failure and requalification costs of up to $10,000.

Q: Should I replace the H5175001 after 15,000 cycles?
A: Yes. While some shields may last up to 18,000 cycles, the recommended replacement interval is 15,000 cycles. Beyond that, the risk of thermal degradation and particulate generation increases, potentially affecting wafer yield.

Q: How much does it cost to repair a failed H5175001?
A: Repair is not typically cost-effective. Most failures require full replacement due to ceramic or heating element damage. Repairs can cost $800–$1,200, but the part is often cheaper to replace outright.

Q: What is the difference between H5175001 and H5175002?
A: The H5175002 has a different ceramic formulation and a revised mounting bracket. It is used in tools manufactured after 2013. Using the wrong model can lead to seal failure and chamber downtime.

Q: How long does a used H5175001 last after installation?
A: On average, a used H5175001 in condition grade B can last 8,000–12,000 cycles after installation. Performance depends on thermal stress and process conditions.
