Leading-edge chipmaking remains concentrated in allied foundries, while China is constrained by access to cutting-edge tools and yields at the smallest nodes.
This layer captures who can reliably produce leading‑edge wafers at scale. Capacity is not enough; yield, ramp speed, and risk concentration decide real output.
Frontier accelerators and high‑end CPUs are constrained by access to the best nodes and stable high yield. Concentration creates systemic risk: a single geography can determine global compute growth.
The strategic advantage is how fast a fab can move from first silicon to high‑volume manufacturing. Tooling, metrology, and process discipline compound.
When leading capacity is concentrated, disruption risk becomes a supply‑chain constraint. Resilience requires both geographic diversification and compatible equipment ecosystems.
Fabrication relies on access to critical minerals for semiconductor manufacturing, including rare earths, gallium, germanium, and other essential materials that form the foundation of the supply chain.
