DeshengxinFFU: The Silent Guardian of Semiconductor Yield in the Nanoscale Era
The Invisible War Against Particles in Chip Fabs
At 3nm process nodes, a single 0.05μm dust particle can distort EUV lithography patterns, scrapping million-dollar wafers. With ISO 1 cleanrooms requiring ≤10 particles/m³ (≥0.1μm), DeshengxinFFU’s advanced filtration and airflow control technologies have become indispensable for leading foundries.
Why Traditional FFU Systems Fail Modern Fabs
Lithography’s Ultra-Sensitive Demands
EUV/DUV lenses require near-zero 0.05μm particle tolerance
±0.1°C temperature shifts cause photoresist deformation
Humidity fluctuations (>±1%) induce nanoscale overlay errors
Legacy FFU Limitations
99.99% HEPA filters insufficient for sub-5nm processes
Turbulent zones from ±15% airflow variation
High maintenance costs and energy waste
