Used Speedfam-IPEC and Novellus CMP Buying Guide

This guide is for: a lab manager or fab engineer who needs a 200mm CMP system under $500k and wants to avoid wasting $150k+ on a lemon with no parts.

I’ve seen three Speedfam-IPEC 6800s in the last month. Two had cracked platen bearings. One had a seller who “upgraded” the polishing head but used a $3k Chinese knockoff instead of the $12k original part. Used CMP systems aren’t like used cars—you can’t just check the odometer. You need to know which models rot from the inside out and which ones still have 80% of their original parts in working order.

If you pick the wrong used CMP tool, you’ll waste $150k–300k in repairs, downtime, and parts that no one stocks anymore. I’m not exaggerating. A customer once bought a 2001 Novellus 4700 for $220k, only to find the motorized carrier was dead and the nearest working one was in a landfill in Singapore. They ended paying $90k for a used motor from a scrap line—after the original $220k*. Don’t let this happen to you.

Which Speedfam Models Are Worth Your Time?

Focus on Speedfam-IPEC 6700 and 6800 systems from 1998–2003. These 200mm CMP platforms are battle-tested. The 6700 is simpler, with fixed polishing heads—great for basic oxide or tungsten steps. The 6800 adds motorized force control, which matters if you’re doing copper CMP. Both use standard 200mm carriers and have parts still in circulation.

Avoid the 5600 series. The platen motor is a single-point failure. I’ve seen them seize up at 12,000 cycles. If you find a 5600, subtract 40% from the asking price unless you want to rebuild the platen yourself. And trust me—no one wants to rebuild a 20-year-old platen.

Used Novellus Systems: 4700 vs. 4900

The Novellus 4700 (1999–2002) is your best bet for 200mm. It has a modular design, so you can swap heads and carriers without scrapping the whole tool. The 4900 (2001–2004) added advanced endpoint detection, but the endpoint module is a $25k part that’s hard to source now. Save your money: the 4700’s endpoint is good enough for most 200mm workloads.

Never buy a Novell0 4500. The wafer backside polish feature sounds fancy, but the abrasive slurry eats through the platen seals. You’ll be replacing $6k seals every 6 months. Stick to the 4700.

200mm CMP Pricing: What You’ll Actually Pay

For a working 6700 or 4700 in a climate-controlled facility, expect $200k–350k depending on the region. Machines with original Entegris polishing pads (not third-party) add $30k–50k to the value. If the seller claims the system has “full documentation,” ask to see the last 3 PM logs—90% of the time, they’ll say “We don’t do that here.”

Compare this to a used AMAT Mirra 200 from 2005–2008. You’ll pay $400k–600k for the same 200mm capability. The Mirra is more reliable, yes—but the consumables are 2x–3x more expensive. A Mirra polishing pad runs $18k vs. $12k for a Speedfam. Over 3 years, that gap adds up.

Consumables: Don’t Assume Parts Are Easy to Find

Speedfam-IPEC and Novellus parts are still available, but you need to know where to look. Polishing pads for 200mm tools cost $8k–15k depending on the material (IC1000 for oxide, IC2000 for copper). Slurry lines and nozzles are $500–$2k each, but the real gotchas are the platen seals ($3k–$6k) and carrier motors ($8k–$15k).

If a seller says “all parts are available,” ask for a quote from a vendor. If they can’t provide one, you’re buying a paperweight. I’ve seen “fully functional” CMP systems where the polishing head motor was clogged with dried slurry—and the replacement motor had been obsolete for 5 years.

Speedfam vs. AMAT Mirra: The Real Trade-Offs

The AMAT Mirra/Reflexion systems are more advanced, but they’re designed for high-volume fabs. For a cost-sensitive lab or mid-sized fab, the older Speedfam and Novellus systems are better. Why? Because they’re simpler to maintain and cheaper to operate.

But don’t dismiss the Mirra outright. If you’re running 24/7 and need minimal downtime, the Mirra’s reliability justifies the price. For 8-hour shifts and sporadic use? The Speedfam 6700 or Novellus 4700 will save you $100k+ upfront.

What to Do Before You Sign

1. Inspect the platen and polishing head. Cracks, scoring, or discoloration mean the system was overused.
2. Ask for the last 6 months of maintenance logs. If they don’t exist, walk.
3. Verify part availability. Get quotes for 3 critical parts before closing.

If you follow these steps, you’ll avoid the $150k trap. Now go find a 6700 or 4700 with a clean platen and original Entegris parts. And for God’s sake, don’t buy a 5600.
