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
