India, Feb. 19 -- Semiconductor manufacturing equipment is the most constrained point of the chip supply chain. Without tools, fabs do not ramp, nodes do not shrink, and capacity plans remain PowerPoint slides.

Equipment determines when, and how fast, silicon supply can respond to demand shocks. Lead times for the most advanced tools stretch across many months, meaning any disruption propagates forward into wafer shortages, delayed node transitions, and higher chip prices.

This "tool gating" dynamic is strongest for leading-edge logic and memory manufacturing. Extreme ultraviolet (EUV) lithography is the clearest example. ASML's near-monopoly makes EUV scanners a structural bottleneck, and the whole advanced-node roadmap depends on its ...
