Plasma Etchers — Used Anatech SP100 (Anatech)

How Much Does Used Anatech SP100 Cost in 2026?

The Anatech SP100 plasma etcher typically sells in the range of $9,500 for a used, refurbished unit in condition grade B. This price is based on units sourced from the 2010–2014 production window, with most units in this range having been refurbished by vendors like Ferrotec and Covalent Materials. A unit in condition grade A (less than 10,000 RF-hours and full diagnostics passed) can command up to $11,000, while a lower-grade B or C unit may be available for as low as $8,500, depending on the seller and the extent of refurbishment.

Compared to a new SP100, which can cost upwards of $24,000, the used market offers 40–60% savings. However, buying a poorly refurbished unit can cost a facility $15,000–$20,000 in downtime and repair costs if it fails within the first six months. Units with more than 12,000 RF-hours or missing critical components like the RF generator (part number SP100-RF-1000) are typically sold at a discount but carry a higher risk of early failure.

Used Anatech SP100 Specifications and Compatible Tools

The Anatech SP100 is a DC plasma etcher typically rated for 100–500 W RF power, with a chamber size of 12" diameter and a base pressure of 1e-5 Torr. It commonly supports gases like CF4, O2, and Ar, and is used in thin-film etching for applications in MEMS and semiconductor packaging. The unit typically has a 10–15 year lifecycle, with most units in the used market having 8,000–12,000 RF-hours.

It is compatible with older Anatech-compatible process modules like the Anatech PM-3000 and PM-3500, used in facilities that require low-cost, high-precision etching. However, it is not compatible with newer Anatech models like the SP200, which use a different RF coupling system. Attempting to retrofit the SP100 into a system expecting the SP200 can lead to $10,000+ in retrofit costs and potential system incompatibility.

What to Check Before Buying a Used Anatech SP100 in 2026

1. RF-Hour Count: Units with more than 12,000 RF-hours should be rejected. High RF usage can degrade the chamber and electrodes, leading to $8,000–$12,000 in replacement costs.
2. RF Generator Test: Run a plasma ignition test and RF power sweep to confirm the generator is functioning within ±5% of rated power. A generator that fails this test is a hard reject.
3. Chamber Leak Test: Use a Helium Mass Spectrometer to test for leaks. A leak rate above 1e-8 Torr·L/s indicates a compromised chamber, which can lead to $5,000+ in vacuum system repairs.
4. Gas System Integrity: Check for corrosion or clogging in the gas lines, especially in the CF4 line. A blocked line can cause $3,000–$5,000 in downtime and part replacement.
5. Production Year: Units made before 2010 often use older, less reliable RF components. These should be inspected more thoroughly or avoided unless a full refurb is included.

Failing to verify these points can result in $10,000–$20,000 in unplanned costs due to early failure or retrofitting.

FAQ

Q: How does the Anatech SP100 compare to the SP200?
A: The SP200 is a newer model with a higher power rating (up to 1,000 W) and a larger chamber (16" diameter). The SP100 is typically limited to 500 W and a 12" chamber, making it suitable for smaller-scale or legacy processes.

Q: Can I use the Anatech SP100 in a high-volume production line?
A: Only if the process requires low-volume, high-precision etching. The SP100 is not rated for more than 10,000 cycles and may fail after 8,000–12,000 RF-hours, which could cost $15,000+ in downtime in a high-volume setting.

Q: How long does a used Anatech SP100 typically last after refurbishment?
A: A well-refurbished unit can last 4–6 years with proper maintenance. Units with 10,000+ RF-hours may only last 2–3 years, especially if the RF generator or chamber is not replaced.

Q: Should I buy a used Anatech SP100 if I need it for a new process?
A: Only if the process is not mission-critical and you can afford $10,000+ in potential repair costs. For new processes, it’s better to invest in a certified refurbished SP200 or a new SP100.

Q: What’s the average lead time for a used Anatech SP100?
A: It’s typically 2–4 weeks after sourcing, but can take longer if the unit needs on-site diagnostics or component replacement.
