SMEE (Shanghai Micro Electronics Equipment) — AI supply-chain exposure

SMEE is China's only domestic maker of lithography scanners — the machines that print circuit patterns onto wafers. It sits at the deepest tool layer of the foundry chain, but its equipment is DUV-class and generations behind the leading-edge systems ASML alone supplies, so today it is strategic rather than substitutive: a hedge against export controls, not yet a replacement for them.

Its structural hook is almost entirely geopolitical. Lithography is the single hardest chokepoint in chipmaking, and China's ability to build advanced logic domestically hinges on closing this gap; SMEE is the national vehicle for trying. That lends it outsized strategic weight relative to its actual capability. The model places it at a modest centrality precisely because of that gap — a supplier of foundry capacity in intent, but constrained to trailing-edge nodes until its tools mature.
