Geopolitical Chokepoint Status: CRITICAL_EXECUTIVE_CONTROL

At 13.5nm wavelength with 11 Zeiss Bragg reflections, overall light transmission is capped at 1.98%. Achieving sub-nanometer atomic flatness on mirrors and synchronizing 50,000 tin droplets per second with a high-power CO2 laser represents the ultimate technological chokepoint. Without ASML and Zeiss supply chains, domestic substitution attempts suffer severe photon starvation, forcing reliance on multi-patterning DUV with high overlay defect rates.
