Lace Helium Lithography Funding: $40M Microsoft-Backed Round Targets Atomic-Scale Chipmaking by 2029

Norwegian chipmaking equipment startup Lace Lithography announced $40 million in Series A funding on March 23, bringing total capital raised to over $60 million since its 2023 founding. The Lace helium lithography funding Microsoft-backed round, led by Atomico with participation from Microsoft’s M12 venture arm, will accelerate development of a revolutionary chip fabrication technology that replaces light with helium atom beams to pattern silicon wafers at atomic resolution. CEO Bodil Holst claims the technology can create chip features 10 times smaller than current systems—a 0.1 nanometer helium beam width compared to the 13.5nm wavelength used by ASML‘s extreme ultraviolet (EUV) lithography tools—with a pilot fab tool targeted for 2029.

Why the Lace Helium Lithography Funding Microsoft Deal Matters

According to Reuters, the Lace helium lithography funding Microsoft round reflects growing investor and government interest in alternatives to ASML’s near-monopoly on advanced lithography as semiconductor manufacturing approaches physical limits of light-based patterning. ASML’s EUV systems cost upwards of $350 million per unit, and no meaningful alternative exists at the cutting edge—creating strategic vulnerabilities for chipmakers entirely dependent on a single supplier.

The Next Web notes that “the chip industry’s most valuable piece of equipment is a machine most people have never heard of,” referring to ASML’s EUV systems. A credible alternative to EUV, even one a decade from commercial deployment, carries strategic value well beyond near-term revenue potential because it reduces dependence on a single choke point in global chip supply chains.

The Lace helium lithography funding Microsoft involvement is particularly notable. M12’s participation signals that even the world’s largest tech companies recognize they may need alternatives to ASML’s roadmap as AI chip demand pushes beyond what light-based systems can deliver at acceptable cost and power efficiency.

How Helium Atom Beam Lithography Works

Traditional lithography uses light to draw chip patterns—a process refined over decades but constrained by physics. According to Tom’s Hardware, light has a diffraction limit determined by its wavelength. ASML’s EUV tools operate at 13.5 nanometers, and going shorter requires higher-energy photons that become increasingly difficult and expensive to generate and control.

Lace’s approach eliminates light entirely. Instead of photons, the company uses a beam of metastable helium atoms to pattern features on silicon wafers. Atoms don’t have a diffraction limit like photons, enabling atomic-resolution patterning theoretically limited only by the size of individual atoms.

“The beam Lace will use to make chips is about the width of a single hydrogen atom, or 0.1 nanometer,” according to Reuters. For context, a human hair is approximately 100,000 nanometers wide. The 0.1nm beam width represents roughly 135 times narrower precision than ASML’s current EUV systems.

John Petersen, Scientific Director of Lithography at Imec—a leading chip research hub—told Reuters that helium atom beams could enable transistor features “an order of magnitude smaller to an ‘almost unimaginable’ degree” compared to current capabilities.

The Technical Breakthrough: AI-Solved Mask Design

According to EU-Startups, the core technical challenge that kept helium lithography theoretical for years was mask design. The mathematical complexity of computing how helium atoms interact with mask patterns was considered “effectively intractable” until Lace developed a proprietary AI-driven algorithm that accelerates computation by over 15 orders of magnitude.

This computational breakthrough transformed helium lithography from physics curiosity to potentially viable manufacturing technology. Rather than requiring years of supercomputer time to design a single mask, Lace’s algorithms enable practical design cycles compatible with chip development timelines.

The Lace helium lithography funding Microsoft round will accelerate refinement of these algorithms and development of full system prototypes integrating the helium beam source, mask system, wafer handling, and metrology equipment required for production-worthy tools.

The 2029 Pilot Fab Timeline

Lace has developed prototype systems and aims to install a test tool in a pilot chip fabrication plant around 2029. According to Tech Startups, CEO Holst acknowledges the challenges: “Turning a lab breakthrough into a production-ready tool is one of the toughest transitions in the chip industry.”

The 2029 timeline provides Lace approximately three years to move from current prototypes to fab-ready systems—aggressive but not unprecedented for well-funded chip equipment startups with strong technical teams. However, chipmakers typically require years of qualification testing before adopting new lithography tools for volume production, meaning commercial revenue likely won’t materialize until the early 2030s at the earliest.

Global Banking and Finance notes that Lace’s technology “could enable feature sizes around 0.1 nm—roughly 100× smaller than ASML’s 13.5 nm EUV systems—potentially unlocking unprecedented chip density and AI performance.” If Lace delivers on these promises, it could extend Moore’s Law decades beyond what light-based lithography can achieve.

Competitive Landscape and Strategic Positioning

The Lace helium lithography funding Microsoft round positions the company within a growing ecosystem of ASML alternatives. According to Tom’s Hardware, several startups are pursuing different approaches:

Substrate and xLight: Developing particle accelerator-driven light sources for EUV or X-ray lithography, with xLight receiving $150 million in U.S. government funding

Canon: Shipped its first nanoimprint lithography tool to Texas Institute for Electronics in September 2024

Prinano: China’s nanoimprint system delivered domestically

Each approach targets different aspects of the lithography challenge, but Lace’s helium beam technology represents perhaps the most radical departure from light-based methods. The Lace helium lithography funding Microsoft backing suggests investors believe the approach has commercial potential despite technical risks.

The Next Web’s analysis highlights geopolitical implications: “A credible alternative to EUV, even one a decade from commercial deployment, carries strategic value well beyond its near-term revenue potential.” ASML’s Netherlands-based operations and export controls on EUV machines to China have made chip lithography a flashpoint in U.S.-China technology competition.

The Lace helium lithography funding Microsoft round includes both European venture capital (Atomico), a Norwegian state climate investment fund (Nysnø), and a Spanish government-affiliated investor (Spanish Society for Technological Transformation)—suggesting the startup is backed for geopolitical optionality as much as commercial trajectory.

Founder Background and Team

Dr. Bodil Holst’s profile is unusual for a chip equipment startup founder. According to The Next Web, she is a Danish-Norwegian physicist who joined the University of Bergen in 2007 and built her research career around nanoscale imaging, molecular-beam lithography, and 2D materials. She holds an affiliated professorship at Bergen while serving as CEO.

Co-founder and CTO Adrià Salvador Palau completed his PhD at Bergen under Holst’s supervision and now operates from Barcelona. The company employs more than 50 people across Norway, Spain, the UK, and the Netherlands—reflecting Lace’s pan-European footprint.

Before founding Lace in July 2023, Holst spent years researching atom beam physics in academic settings, providing deep technical expertise but limited commercialization experience. The Lace helium lithography funding Microsoft round brought in Atomico, a European VC with significant operational resources, to help navigate the transition from research to commercial deployment.

Integration With Existing Fabs

A critical advantage Lace claims over some alternative lithography approaches is compatibility with existing foundry workflows. According to EU-Startups, Lace’s BEUV (Beyond-EUV) system “integrates smoothly into existing foundry workflows with minimal infrastructure modifications.”

This matters because chipmakers have invested tens of billions of dollars in fabs optimized for light-based lithography. If helium lithography required entirely new fab designs, adoption barriers would be prohibitive regardless of technical performance. By designing systems that slot into existing infrastructure, Lace reduces customer switching costs and accelerates potential adoption if the technology proves viable.

However, “minimal infrastructure modifications” is marketing language that will be tested during pilot deployments. Real-world fab integration typically reveals countless issues not apparent in lab prototypes, requiring iterative refinement that can stretch timelines significantly.

What This Means for Moore’s Law

The Lace helium lithography funding Microsoft round represents a bet that Moore’s Law—the observation that transistor density doubles roughly every two years—can continue far beyond what industry roadmaps currently project. According to Tech Startups, “if helium atom lithography proves viable at scale, it could extend the life of Moore’s Law in a way many thought was slipping out of reach.”

Smaller transistors deliver multiple benefits: more compute power in the same chip area, reduced power consumption per operation, and lower manufacturing cost per transistor at volume. For AI applications where computational demands grow exponentially, continuing transistor scaling matters enormously for keeping costs manageable while improving performance.

However, achieving atomic-scale transistors requires solving problems beyond just lithography—materials science, heat dissipation, quantum effects, and manufacturing defect rates all become increasingly challenging at smaller scales. Even if Lace’s lithography works perfectly, building functional chips at atomic dimensions may prove impossible for reasons unrelated to patterning technology.

Looking Ahead

The Lace helium lithography funding Microsoft round provides capital to pursue an audacious technical vision, but significant execution risks remain. Moving from prototypes to production-qualified tools requires solving countless engineering challenges, securing design wins from major chipmakers, manufacturing at scale, and competing with ASML’s decades of refinement and ecosystem lock-in.

For the semiconductor industry, Lace represents one of multiple bets on alternatives to light-based lithography as physics approaches fundamental limits. Whether helium atom beams, nanoimprint, new light sources, or entirely different approaches ultimately succeed matters less than ensuring multiple paths forward exist beyond ASML’s roadmap.

For Microsoft and other tech giants dependent on cutting-edge chips, the Lace helium lithography funding Microsoft investment hedges against ASML monopoly risks while supporting development of potentially transformative manufacturing capabilities. If Lace succeeds, chipmakers gain a new tool for pushing transistor density toward atomic limits. If it fails, Microsoft’s investment represents a relatively small bet on a potentially industry-reshaping technology.
