Lithography equipment

Lithography machines print chip patterns onto silicon wafers, and the most advanced kind — extreme-ultraviolet, or EUV — is built by exactly one company on earth: ASML. Each tool costs hundreds of millions of dollars, the newest High-NA generation roughly twice the last, and only a limited number leave the factory each year. That combination makes tool allocation the quiet scheduler of the whole AI buildout: every leading-edge fab expansion, whoever announces it, ultimately queues for a build slot at a single supplier. The generational handoff is happening now — Intel has accepted the first production-grade High-NA tool while TSMC publicly defers the new generation on cost grounds — so the queue itself has become strategy.

The failure mode is absolute in a way almost nothing else in the chain is: a disruption at the sole EUV supplier, or a widened export-control regime, caps how fast the world can add leading-edge capacity for years, with no substitute vendor to route around. EUV tools have never shipped to China under Dutch–US export controls, which is why this node doubles as a geopolitical instrument. ASML stands alone at the top; Nikon and Canon persist in older optical grades, and the fabs that depend on the machines — TSMC, Samsung and Intel — compete for every slot.
