How Much Does KLA 2351 Overlay Metrology System Cost in 2026?

Used systems price between $189,000–$315,000 in 2026, depending on calibration history and optics condition. Refurbished units (with <18-month-old laser modules and full software updates) add 12–18% to the base price. New systems from KLA exceed $525,000, offering 37–50% savings by opting for used. Critical caveat: systems with >5 years since last metrology calibration (per KLA-2351-TC-003 specs) require mandatory recalibration at ~$28,000, often unaccounted in initial budgets.

KLA 2351 Specifications and Compatible Tools

Overlay accuracy: ±0.8 nm (3σ) at 248nm wavelength. Throughput: 120 wafers/hour (200mm). Power draw: 3.2 kW at 208VAC, 50/60Hz. Compatible with KLA 2350 (2001–2007), 2351 (2003–2010), and 2360 (2005–2012) systems. Also integrates with Applied Materials Centura platforms (pre-2015) via KLA-2351-IF-01 interface module. Exclusion: Not compatible with KLA 2380 systems (2018+) due to incompatible StageControl v4.2+ firmware. Verify tool’s metrology port dimensions (min. 450mm x 320mm clear space required).

What to Check Before Buying a Used KLA 2351 in 2026

  1. Laser stability: Use a wavemeter to confirm 248nm emission deviation <±0.05nm (spec per KLA-2351-MT-001).
  2. Optics contamination: Inspect beam splitter for >5% haze (measured via integrating sphere, reject if >3% light loss).
  3. Stage repeatability: Run 50-cycle XY stage test; reject if standard deviation exceeds 1.2nm (per KLA-2351-TS-007 protocol).
  4. Software lifecycle: Systems with K2OS v3.9
