How Much Does Lam Research 716-044863-428 Cost in 2026?

Used units range from $15,000 to $25,000 in 2026, with refurbished variants priced $10,000–$18,000. New OEM pricing exceeds $50,000, offering ~60–70% savings for used/refurbished options. Caveat: Units with >50,000 operational cycles (per Lam’s lifecycle metrics) may require derating, reducing effective savings by 15–20%. Market demand remains stable due to 4xx Series tool prevalence in legacy 300mm etch processes.

Lam Research 716-044863-428 Specifications and Compatible Tools

Key specs: 12 kV DC voltage rating, 500 W max power, 0–5 SLPM helium flow, and flat ceramic substrate (15.2 mm thickness). Compatible with Lam 450, 460, and 470 Series etch chambers (models 4520, 4620, 4720) produced 2008–2015. Exclusion: Not compatible with 480 Series (e.g., 4820) due to differing mounting bracket geometry (part number 716-044863-480). Verify tool’s vacuum interface (ISO-KF40) and chuck ID (Ø305 mm) before installation.

What to Check Before Buying a Used Lam 716-044863-428 in 2026

Ceramic integrity: Inspect for microcracks via 10X magnification; reject if >3 surface flaws per 10 cm².
Insulation resistance: Measure with a 10kV megohmmeter; must exceed 1×10¹² Ω (per JIS C 2113).
Helium leak rate: Test with a mass spectrometer; leakage must be <1×10⁻⁸ std cm³/sec (ASTM E1418).
Cycle count: Units with >80,000 cycles (per Lam’s 2012 whitepaper) risk thermal gradient failure.
Firmware compatibility: Confirm ESC controller revision (V4.3–V4.7) matches tool’s PLC protocol.
