Industry Analysis
ASML’s near-total dominance in EUV lithography is triggering a cascading upgrade across the semiconductor stack: TSMC, Samsung, and Intel’s race for High-NA EUV tools is compressing sub-3nm ramp timelines and forcing co-evolution in EDA, photoresists, and mask infrastructure. Geopolitical friction inflates compliance overhead—while U.S. export controls haven’t yet blocked ASML’s DUV shipments to China, tightened scrutiny on components already extends lead times and inventory costs. With Nikon and Canon effectively locked out of EUV, Tokyo Electron is pivoting to integrated track systems to embed itself deeper into ASML’s ecosystem. Over the next 12–24 months, surging AI chip demand and recovering fab capex will let ASML monetize its technology gap, making its tool installations the definitive leading indicator of advanced-node capacity expansion.
