In the nano-scale world of chip manufacturing, equipment frames and bases form the “lifeline” of lithography scanners, etch chambers, and CVD reactors. Where <1μm vibration errors impact yield, and metal ion release contaminates EUV optics, only aerospace-grade stainless steel and molecular-level cleanliness can safeguard chip fabrication. We specialize in mission-critical structural components with zero distortion, zero outgassing, and zero magnetic interference for 3nm node resilience.
I. Semiconductor “Foundation” Challenges

|---|---|---|
| Micro-Vibration | >5nm @100Hz | Hybrid damping + honeycomb ribs |
| Thermal Drift | ΔL>0.1μm/°C | CTE-matched design (≤9.5×10⁻⁶/K) |
| Metal Contamination | >0.1 particles/cm²·min | EP + scCO₂ cleaning |
| Residual Magnetism | μr>1.002 | Non-magnetic steel (μr<1.0005) |
| Wafer-Level Flatness | >0.02mm/m² | Stress relief + nano-scraping |
