Our Purpose — Substrate

00 The decline

Three decades ago, the United States made nearly 40% of the world's chips. Today it makes around 12% — and the trend is still falling.

U.S. share of global chip fabrication capacity

Heritage

America invented the chip. Then it let the factory leave.

The transistor, the integrated circuit, even EUV lithography — all born in the United States. But the hardest part, turning that science into tools and running the fabs, drifted overseas, leaving the lithography monopoly to a single foreign company. Substrate exists to bring that crown jewel home.

What we believe

01

The cost of semiconductor fabrication is out of control, and it will only continue to trend upward without radical new technological innovation.

02

The United States is dangerously reliant on sources of geopolitical and supply-chain risk that we do not directly control.

03

The only chance to return to dominance is to create a new type of more vertically-integrated foundry.

The number that drives us

$0 Industry trajectory · 2030

$0 Substrate · 2030

$10,000 per wafer by 2030 against a projected $100,000 — extending Moore's Law in both performance and cost, and democratizing access to advanced chip design and production.

Cost per wafer · the divergence

Same decade. Two trajectories.

Left to the industry's curve, a leading-edge wafer reaches $100,000 by 2030. Our integrated foundry drives it to $10,000 — the 10× gap that decides who can afford to build.

Cost to build a leading-edge fab

Rock's Law

The cost of a fab doubles every four years.

Each leading-edge fab costs roughly twice the last. A 2030 fab will run past $50 billion — and that cost lands on every wafer. Unchecked, the curve prices out all but a handful of giants. We are built to break it.

AI & silicon

AI can design the chip. It still can't build it.

Modern AI already designs chips faster and cheaper than any human team — design cost is collapsing toward zero. That leaves one bottleneck for the entire AI era: fabrication. Substrate sits exactly there, closing the loop between the models and the silicon they run on.

The vision

Silicon wafer · 300mm

A vertically-integrated foundry, powered by particle accelerators.

We are developing a foundry that uses particle accelerators to produce advanced X-ray lithography — manufacturing at dramatically reduced costs, extending Moore's Law, and putting cutting-edge silicon back within reach of American industry.

The U.S. lost its lead to rising fab costs, supply-chain vulnerability, and the rapid advance of competitors abroad. We intend to win it back.

Failure is not an option. We must try.
