Substrate is building a next-generation foundry to return America to dominance in semiconductor production. To achieve this, we will use our technology—a new form of advanced X-ray lithography—to power them. America invented semiconductors. We will lead again.

History repeatedly shows that American science and engineering solve impossible tasks. I started Substrate because I believed that this impossible task is one worth trying.

The United States invented all of the critical technologies that power today’s advanced semiconductors, but over time, we have lost the lead. For years, many have spoken of the need for a new pure-play American foundry, yet view it as an impossible task. History repeatedly shows

These patterns have been printed using a Substrate lithography system with no IP or supply chain input from other advanced lithography tools. The resolution of the features in these images is equivalent to that achievable only with what the semiconductor industry refers to as
