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.

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 “High NA EUV lithography” and matches features printed at the 2 nm semiconductor node and below. All of these images were printed in a single exposure, with no multi-patterning.

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 that American science and engineering solve impossible tasks. As we rush to build more current-generation semiconductor fabs in America today, we need to start immediate work on building the semiconductor fabs of tomorrow. The stakes are too high for the United States not to try everything we can to solve both one of our most significant technological gaps and our biggest opportunities to reclaim leadership over the technologies we pioneered.

We are so back

How are you going to make sure this tech isn't stolen through espionage, like so many other technologies have?

At least ASML has prepared for this by investing billions in Mistral.

I’m in

incredibly based. god speed, kings.

incredible

Time to onshore advanced chips

Tuffff

investing at 1k views

can't wait to sell this to the dutch again

How large can you make them and at what cost? That’s the biggest issue with semiconductors besides power constraints. Semiconductors have been around for years but building them cheap enough to be useful to average consumers or scaling for larger projects hasn’t been possible.

soo tuff

This is huge. Love to see it!

ACCELERATE

In the real world it’ll never have the throughput. It’s why this was tried and shelved in the 90s. Serial exposure (direct write), higher dose requirement and high source power. Repeating the greatest hits on why x-ray and e-beam got dropped. Plus overlay is a disaster

I know just the place

Yes! My mother worked at PSI, Pacific Semiconductor in Southern California in the early 1960s! Bring it all back! 🙌🇺🇸🙌

And they did not flinch

Just please make sure to cyber harden your networks and also 2nd and 3rd tier suppliers so that China does not pilfer your IP as they have done w/so many other American technologies.

Cool, how can I invest?

LETS GOOOOO

Congratulations for @substrate Stunning achievement. Robert Noyce is cheering excitedly from heaven.

Glad we are onshoring this process, hopefully it stands the test of time.

finally an ASML contender in the US

@katebomb we should

Developing a X ray projection system when gold prices are spiking sure is a choice

@asianometry pls make video. Thks

this was almost me 😉

Let’s fucking go!!!

let's gooo. keep going! 🇺🇸

Outstanding achievements by a small team with a great vision. Congratulations.

X-ray lithography at scale is the wildcard. If Substrate pulls this off, it rewrites the global semiconductor playbook.

Let’s go
