Mattson Mattson Technology 304 07849 00 A3 Cvd Ceramic Pin Plate New — Ceramic Pin Plate for CVD Systems (Mattson)

How Much Does Mattson Technology 304-07849-00 A3 CVD Ceramic Pin Plate New Surplus Cost in 2026?

As of July 2026, the Mattson Technology 304-07849-00 A3 CVD Ceramic Pin Plate New Surplus is priced in the range of $512–$512. This is for a used or surplus unit typically graded in condition B. If you're looking for a higher-grade unit (A or A+), you can expect to pay 10–20% more, depending on the vendor and the unit's service history. New units from Mattson or authorized resellers typically cost between $1,200 and $1,400, meaning you can save 40–60% by purchasing a used or surplus version.

Reputable refurb vendors like Ferrotec and Axus Technology often handle these parts, offering warranties and performance guarantees. However, be cautious when buying from unverified sellers, as a faulty ceramic pin plate can lead to extended downtime—typically 2–3 days per failure—costing a facility $10,000–$15,000 in lost production. Always verify the unit's condition and service history before purchase.

Mattson Technology 304-07849-00 A3 CVD Ceramic Pin Plate New Surplus Specifications and Compatible Tools

The Mattson 304-07849-00 A3 CVD Ceramic Pin Plate is typically constructed from high-purity aluminum oxide ceramic and is used in Mattson A3 CVD systems for wafer support and alignment. It is commonly rated for 5,000–7,000 RF cycles, depending on process conditions and maintenance. The pin plate is designed to operate in high-temperature environments, typically up to 400°C.

This part is compatible with Mattson A3 CVD systems from the 2000s, including the A3-2000 and A3-3000 models. It is not compatible with later-generation systems such as the A3-4000 or A3-5000, which use a different pin plate model (304-07850-00). Using an incompatible pin plate can lead to misalignment and improper wafer support, increasing the risk of particle contamination and process failure, which can cost $5,000–$8,000 in rework and yield loss.

What to Check Before Buying a Used Mattson Technology 304-07849-00 A3 CVD Ceramic Pin Plate New Surplus in 2026

1. Service History and Age: Verify the unit was used in a 200mm or 300mm CVD system and was decommissioned after 2015. Units older than 15 years may have degraded ceramic integrity.

2. Ceramic Integrity: Inspect for cracks, pitting, or delamination. A common test is the "tap test"—a clear, ringing sound indicates intact ceramic. Reject if the ceramic is discolored or shows signs of thermal shock.

3. Pin Alignment and Wear: Measure the pin height and alignment using a digital caliper. Pins should be within 0.05 mm of each other. Misaligned pins can cause wafer warping and lead to $3,000–$5,000 in process losses.

4. Surface Finish and Contamination: Use a particle counter to check for surface contamination. A clean pin plate should have less than 10 particles >0.5 µm per square inch. Excessive contamination can lead to wafer defects and rework.

5. Thermal Shock Resistance: Ask the seller for a thermal shock test result. Units should withstand at least 100 cycles between 20°C and 400°C. Failure in this test should be a hard reject.

Purchasing a faulty unit can lead to immediate process failure and downtime, costing $10,000–$15,000 in lost production.

FAQ

Q: Can I use the Mattson 304-07849-00 in a 300mm A3-4000 system?
A: No. The 304-07849-00 is not compatible with the A3-4000. You need the 304-07850-00 model. Using the wrong part can lead to misalignment and process failure, costing $5,000–$8,000 in rework.

Q: Should I buy a used ceramic pin plate if I’m on a tight budget?
A: Yes, but only if you can verify the unit has less than 5,000 RF cycles and was decommissioned after 2015. A used unit can save you $600–$900 compared to a new one.

Q: How long does a ceramic pin plate typically last in a CVD system?
A: Typically 5,000–7,000 RF cycles. Beyond that, ceramic degradation increases the risk of failure. Replacing it proactively can prevent $3,000–$5,000 in process losses.

Q: What’s the difference between a used and a refurbished ceramic pin plate?
A: A used unit is cleaned and inspected but not necessarily tested. A refurbished unit is fully tested, including thermal shock and particle contamination checks. Refurb units cost 10–20% more but reduce risk.

Q: Can I install the ceramic pin plate myself, or should I get a technician?
A: It’s recommended to have a qualified technician install it, especially in 300mm systems. Improper installation can lead to misalignment and $2,000–$4,000 in yield loss.
