About the Company

Substrate

Develops advanced X-ray lithography chipmaking system

Substrate develops a new chipmaking platform that uses advanced X-ray lithography powered by a proprietary particle accelerator to pattern circuitry on silicon wafers, with the aim of building a vertically integrated U.S. foundry. The technology claims to cut lithography costs roughly in half and has been demonstrated at national laboratories and its own facilities, with first chips targeted for 2028. Unlike traditional suppliers, Substrate pursues domestic production to reduce reliance on overseas fabs and focuses on cost-efficient, leading-edge wafers for AI and robotics. Its goal is to restore U.S. leadership in advanced semiconductor manufacturing and improve supply‑chain resilience by offering a domestic, cost-effective path to making high-end chips.
