FAQ
Q ISO Class 1 vs old 100 classification?
A
ISO 14644-1 Class 1 ≈ US Federal Std 209E Class 1 (≥ 0.5 μm particles per ft³). Class 1 for litho; Class 5 for assembly; Class 7 for public areas.
Q Why are semi tools so expensive?
A
ASML EUV lithography $150-300M each. Reasons: sub-nm tolerances, ultra-purity, millisecond stability, 50,000+ patented parts.
Q China semiconductor import restrictions?
A
US + Japan + Netherlands restrict sub-14 nm advanced-node tools; mature nodes (28 nm+) mostly still importable. 0so tracks compliance lists.
Q Fab maintenance specifics?
A
24/7 zero-downtime; spare-parts SLA 4 h on-site; resident technicians; component traceability to wafer batch. Siemens and Beckhoff have dedicated semiconductor IPC and motion lines.
