Substrate is not just another startup. It was founded in 2022 by brothers James and Oliver Proud, and is backed by Peter Thiel (he co-founded PayPal and is one of the largest investors in Silicon Valley). Despite having existed for only four years, it has raised more than 100 million dollars and has been valued at more than 1 billion. This very successful start-up is based on a promise: the Proud brothers claim that they can build photolithography equipment as advanced as the most sophisticated they have. the Dutch company ASML.
Currently this firm from the Netherlands is the only one capable of manufacturing the machines extreme ultraviolet lithography (EUV) that are used to produce cutting-edge semiconductors, which has placed it in an effective monopoly position in the global semiconductor industry. In the current scenario of confrontation with China, the US is interested in having a national company capable of manufacturing cutting-edge lithography equipment. This is Substrate’s trump card. However, we have reasonable grounds for reluctantly taking up the promise of the Proud brothers.
“No one is coming for us”
Christophe Fouquet, the general director of ASML, assures that no company on the planet is in a position to compete with them. During a conversation with Connie Loizos, an editor at TechCrunch, Fouquet has argued that “the challenges of lithography are many. Being able to make an image is a starting point, but that image must be produced in large quantities, at very low cost, at high speed and with nanometric precision.” It makes sense.
“We had to solve only one problem: obtaining extreme ultraviolet light. And that alone took us 20 years”
“I always say that the only reason ASML was able to build an EUV machine is because 80% of it already existed from prior knowledge and products developed over time. We had to solve just one problem: getting the extreme ultraviolet light. And that alone took us 20 years. When starting from scratch, the challenge is enormous. I have heard many statements. And I have seen some images. But we got our first image with EUV technology 30 years ago, and even then we need 20 more years of hard work to turn it into a manufacturing system,” points out the head of ASML.
It is clear that Christophe Fouquet trusts his technology. And in your product. However, the starting point of Substrate is different from that of ASML. This American startup uses a particle accelerator as a light source for an X-ray lithography tool instead of using extreme ultraviolet light like ASML. According to the Proud brothers Their technology allows them to manufacture a silicon wafer at an order of magnitude lower cost than with ASML’s EUV approach.
Be that as it may, there is another fundamental difference between the ASML and Substrate strategies. And instead of supplying machines to chip manufacturers, as ASML does, Substrate wants to establish its own network of semiconductor production plants equipped with its photolithography machines. Furthermore, its plan is very ambitious: it aims to produce cutting-edge integrated circuits on a large scale in 2028. It sounds daring, no doubt, but time, as always, will put everything in its place.
