Used AMAT Mirra and Reflexion CMP Buying Guide: Models, Consumables, and Pricing

This guide is for: a semiconductor plant manager or engineer tasked with buying a used CMP tool but unsure which model to pick, how to inspect it, or what hidden costs lurk.

I sold a Reflexion 7200 to a startup last year. They got it for $950k, thinking they’d scored. Six weeks later, the slurry distribution manifold clogged—$40k part, $15k labor to replace. They’d skipped the inspection. Don’t let this be you.

Here’s the truth: used CMP tools are a numbers game. A Mirra 6600 will cost you $500k–$1.2M depending on condition. A Reflexion 7200 or 7300 runs $800k–$1.5M. But these are just entry tickets. Over three years, consumables alone will eat $200k–$300k for a Mirra, $250k–$400k for a Reflexion. Head seals, platens, and slurry lines rot. I’ve seen 30% of used CMP tools fail within six months due to neglected maintenance.

**Should You Buy Mirra or Reflexion?**  
Mirra (6600/6700 series) is the workhorse. Pro: modular design makes repairs cheaper. Con: older models lack endpoint sensors. Reflexion (7200/7300) has better automation but tighter tolerances—its slurry pumps fail 2x more often than Mirra’s. Ask: do you need advanced process control? If yes, pay the premium. If not, Mirra’s your bird.

**Which Consumables Drain Your Budget?**  
Platen condition is king. A worn platen reduces polishing uniformity; replace if the surface is pitted or shows >50µm wear. Head seals? They leak after 5k–8k wafer lots. Stock up on [slurry distribution parts](/parts/cmp-slurry-distribution) too—those micro-tubes clog like arterial plaque. I’ve priced used Reflexion slurry manifolds at $35k–$60k; don’t let a “clean” tool hide old, cracked lines.

**Why Pricing Varies 40% Between Buyers**  
Condition, age, and maintenance history decide value. A Mirra with <10k lots and fresh platens? $1.1M. Same tool with 25k lots and a clogged platen? $750k. Seller honesty matters. Ask for PM records, last major overhaul date, and wafer throughput data. If they can’t provide these, walk. Or offer $200k less and budget for surprises.

**Common Failures to Name-Check in Inspections**  
- Motor controller boards (Mirra 6600: 20% failure rate after 8 years)  
- Endpoint detection sensors (Reflexion 7300: $25k–$35k replacement)  
- Polishing head actuators (leaks = $10k–$15k repair)  

**FAQ**  
*"How much does a used AMAT Mirra CMP cost?"*  
$500k–$1.2M. Older models (pre-2010) drop to $400k but expect $100k+ in refresh costs.  

*"What’s the failure rate of used CMP tools?"*  
30% fail within 6 months due to hidden platen or seal damage. Inspections cut this to 10%.  

*"How much do CMP slurry parts cost?"*  
A used Reflexion slurry manifold: $35k–$60k. Mirra’s simpler system: $20k–$40k.  

*"Which CMP model is more reliable?"*  
Mirra 6600/6700 series. Reflexion 7200+ needs stricter maintenance.  

**Next Steps**  
1. **Audit the platen**: Reject any with >50µm wear or resin cracks.  
2. **Check head seal life**: Ask for lot count and leak test records.  
3. **Verify slurry lines**: Replace if they’re >5 years old or show discoloration.  
4. **Negotiate based on PM history**: Use maintenance gaps to lower the price 15–30%.  

Buying used CMP isn’t magic. It’s about knowing what breaks, how much it costs to fix, and who’s lying. Start here, and you’ll avoid the $40k manifold trap.
