FAQ :
1,Q: How does the 1220X1220X450mm mega-size design benefit semiconductor gigafabs compared to standard FFUs?
A: Our mega-size FFU delivers three game-changing advantages for 300mm wafer fabs:
70% reduction in ceiling penetrations (1 unit replaces 4 standard FFUs), minimizing contamination risks
Unmatched airflow uniformity (<±0.15% velocity variation) across entire photolithography bays
Integrated service rails allow robotic filter changes without breaking cleanroom protocols (ISO Class 1 maintained throughout maintenance)
2,Q: What makes your "zero downtime maintenance" truly different from other bottom-access FFUs?
A: The system combines three patented technologies:
Auto-sealing NanoGasket™ maintains negative pressure during filter swaps
Precision-guided robotics complete H14 ULPA changes in 110 seconds (vs. 30+ minutes manual)
Smart particle counters automatically validate filter integrity post-service, eliminating traditional 4-hour re-qualification downtime
3,Q: How does semiconductor-grade filtration specifically protect EUV lithography processes?
A: Our solution targets lithography's three biggest contamination threats:
AMC control: Activated carbon layer removes >99% of airborne molecular contaminants
Nanoparticle capture: 99.9995% efficiency on 0.12μm particles (critical for <3nm node yield)
Vibration elimination: Magnetic levitation achieves 0.03μm/s vibration - 10x better than ASML's requirements
