About

Our revolutionary X-ray lithography harnesses light billions of times brighter than the sun.

01  What we do

STORAGE RING · X-RAY SOURCE X-RAY

A foundry, not just a tool.

Substrate develops advanced lithography that accelerates electrons through magnetic fields to create semiconductor features at extreme precision — pushing Moore's Law forward. We are building and operating a vertically-integrated foundry on American soil, offering foundry services rather than selling tools.


02  Trajectory

2022

Founded to return the United States to dominance in semiconductor fabrication.

2025

Out of stealth. $100M raised at a ~$1B valuation; pivot to building and operating U.S. fabs.

2028

Targeting initial large-scale chip production.

2030

$10,000 per wafer — against a projected industry cost of $100,000.



04  Founder

James Proud

Founder & CEO. A first-principles builder with deep experience in global hardware and supply chains, driven by the conviction that the rising cost of fabrication demands an entirely new technology paradigm — and that American semiconductor sovereignty is worth fighting for.
