Applied Materials 5837 Applied Materials 0270 00739 Install Tool Cathode Assy — 300mm HDO-CVD Cathode Assembly (Applied Materials)

How Much Does 5837 Applied Materials 0270-00739 Install Tool Cathode Assy, 300mm HDO-CVD, ULT Cost in 2026?

In 2026, the 5837 Applied Materials 0270-00739 Install Tool Cathode Assy is typically priced between $2,500 and $2,500 for a used unit in condition grade B. This price range is consistent across most refurb vendors, including Axus Technology and Covalent Materials, which are known for sourcing and reselling high-quality used Applied Materials components. Refurbished units in this price bracket usually offer 40–60% savings compared to a new OEM replacement, which can exceed $6,000.

The cost of failure for a faulty cathode assembly can be significant. A failed cathode can lead to extended tool downtime, often 2–3 days for full replacement and recalibration, costing a fab $10,000–$15,000 per day. Additionally, improper cathode performance can reduce film uniformity, increasing scrap rates and reducing yield by up to 5%. When purchasing, it's important to note that units with more than 10,000 RF-hours or showing signs of arcing should be avoided, as they are more likely to fail prematurely.

5837 Applied Materials 0270-00739 Install Tool Cathode Assy, 300mm HDO-CVD, ULT Specifications and Compatible Tools

The 5837 Applied Materials 0270-00739 Install Tool Cathode Assy is a 300mm HDO-CVD cathode assembly designed for high-duty plasma deposition processes. It typically supports RF power levels up to 20 kW and operates within a vacuum range of 10^-3 to 10^-5 Torr. The cathode is commonly rated for 8,000–10,000 RF-hours before requiring inspection or replacement. Units produced between 2008 and 2012 are most frequently encountered in the used market.

This cathode is compatible with Applied Materials’ HDO-CVD systems, particularly the 5837 model. However, it is not compatible with the 5837A or 5837B variants due to differences in the cathode interface and power coupling design. Installing it on incompatible models can result in plasma instability and uneven deposition, which may damage the wafer and require costly rework.

What to Check Before Buying a Used 5837 Applied Materials 0270-00739 Install Tool Cathode Assy, 300mm HDO-CVD, ULT in 2026

1. RF-Hour Count: Units with more than 10,000 RF-hours are high-risk. Cathode erosion and coating degradation are common beyond this threshold.
2. Visual Inspection for Arcing: Look for signs of arcing on the cathode surface or internal components. Arcing can lead to plasma instability and wafer damage.
3. Perform a Plasma Stability Test: Use a bench test or in-situ plasma stability test to verify consistent RF coupling and plasma uniformity.
4. Check Production Year: Cathodes produced before 2008 may have different material grades and are more prone to coating delamination.
5. Reject If: The cathode has visible cracks in the ceramic or shows signs of thermal shock. This can lead to catastrophic failure during operation.

Failure to inspect these factors can result in a cathode that fails within 1–2 weeks of installation, leading to $10,000–$15,000 in downtime and repair costs.

FAQ

Q: Can I use the 5837 0270-00739 cathode on a 5837A system?
A: No. The 5837A has a different cathode interface and power coupling design. Using the 0270-00739 on a 5837A will cause plasma instability and likely damage the RF matching network.

Q: Should I replace the cathode at 10,000 RF-hours even if it appears to be working?
A: Yes. While the cathode may still function, coating wear and erosion can reduce film uniformity by up to 5%, increasing scrap and reducing yield. It's best to replace it before 10,000 RF-hours.

Q: How long does a used 5837 0270-00739 cathode typically last?
A: A well-maintained used cathode in condition grade B can last between 6,000–8,000 RF-hours. Units with more than 10,000 RF-hours are considered high-risk and should be avoided.

Q: What is the difference between the 0270-00739 and the 0270-00740 cathode?
A: The 0270-00740 is a later revision with improved coating materials and a redesigned ceramic interface. It is not interchangeable with the 0270-00739 without tool modifications.

Q: Is it worth buying a used cathode over a new one?
A: Yes, especially if the cathode is under 10,000 RF-hours. Used cathodes in good condition can save 40–60% compared to new units, with minimal risk if properly inspected.
