Every chip in every laptop, data center, and AI server exists because someone figured out how to draw impossibly small lines using light. Photolithography, the process of projecting patterns onto silicon wafers, has been the foundation of the semiconductor industry for half a century. The latest version, extreme ultraviolet (EUV), uses light with a wavelength of 13.5 nanometers. It's a marvel of physics and engineering. It also costs $400 million per machine, and there's only one company on earth, ASML, that can build them.

Lace Lithography wants to skip past all of that. The Bergen, Norway startup just raised $40 million in a Series A led by Atomico to develop lithography systems that use a beam of helium atoms instead of light. The theoretical advantage is enormous: helium atoms have a de Broglie wavelength vastly shorter than EUV light, enabling features up to 10 times smaller than what's currently possible.

Ten times smaller. Let that sink in for a moment. We're talking about patterning at the scale of individual atoms, in a world that's already struggling to manufacture at 2 nanometers.

The company was founded in July 2023 by Professor Bodil Holst of the University of Bergen and CTO Adria Salvador Palau. Holst's research in neutral atom optics stretches back years, well before the current semiconductor supply chain panic made chip sovereignty a dinner table conversation in Brussels and Washington.

Her insight was this: photons have limits. As you push wavelengths shorter, the engineering challenges multiply exponentially. EUV already requires vacuum environments, mirrors coated with 80 alternating layers of molybdenum and silicon, and a plasma source that vaporizes tin. Going beyond EUV with even shorter wavelength light (sometimes called High-NA EUV) is possible but increasingly impractical and expensive.

Atoms offer a different path. A focused beam of neutral helium atoms has the right quantum properties for nanoscale patterning, and atoms don't carry charge, which eliminates certain damage mechanisms that plague ion-beam and electron-beam techniques. They also don't generate secondary electrons that blur pattern edges.

Atomico led the round. M12, Microsoft's venture fund, joined alongside Linse Capital (Jensen Huang's family office, for those keeping track), Vsquared Ventures, Future Ventures, Runa Capital, Deep Future, SETT Spain, and Nysno Climate Investments, Norway's state-backed climate investment fund.

Nysno's presence is worth pausing on. A climate fund investing in semiconductor lithography. The reasoning: current EUV systems are energy hogs. More efficient manufacturing processes could materially reduce the carbon footprint of chip production, which matters when AI is driving explosive growth in data center buildouts.

Here's the honest assessment: Lace Lithography is building something that doesn't exist yet. Not as a product, not as a prototype in a fab. The company is targeting a pilot tool deployment in a semiconductor fabrication facility by around 2029. That's three years away, minimum. In semiconductor terms, that's one or two process node generations.

The company's current business model involves licensing and consulting, providing access to its technology and technical services for semiconductor companies doing mask development, process optimization, and R&D. That generates some revenue while the main product gets built. It's the classic deep-tech playbook: stay alive with services while the breakthrough technology matures.

Norway isn't where you'd expect a semiconductor lithography company to emerge. The country is known for oil, fish, and sovereign wealth. But Bergen has a quietly strong physics department, and the intersection of Norwegian deep-tech research funding with European chip sovereignty ambitions creates an environment where a company like Lace can get started.

The $40 million Series A is substantial for a company less than three years old, especially one attempting something this technically ambitious. But compared to the billions flowing into semiconductor infrastructure globally, it's a rounding error. If atom-beam lithography works at scale, Lace Lithography won't need another Series A. It'll need a factory. And the line of customers waiting outside will stretch around the block.
