Trump Administration Invests $150M in Startup Aiming to Break ASML’s Chip Monopoly

The Trump administration has announced plans to inject up to $150 million into xLight, a U.S. chip laser startup developing next-generation semiconductor manufacturing tools. The investment will come through the Department of Commerce’s CHIPS Research and Development Office under the CHIPS and Science Act, with the government taking an equity stake in the company.

xLight is a startup that is trying to change how the most advanced computer chips are made. Today, chip factories use a very special kind of light called extreme ultraviolet, or EUV, to print tiny patterns on silicon wafers. The only company that makes these EUV machines is ASML in the Netherlands, and their system works by firing powerful lasers at droplets of tin to create the light.

xLight wants to do this differently. Instead of hitting droplets with lasers, it is developing what’s called a free‑electron laser. This machine speeds up electrons and makes them release light directly, which can be tuned to the exact wavelength needed for chipmaking. If successful, this approach could be simpler, more efficient, and potentially cheaper than the current method.

The particle accelerator approach is at the heart of what xLight is trying to do with its free‑electron laser technology. The particle accelerator approach that xLight is pursuing is essentially about using beams of electrons to generate the special light needed for advanced chipmaking. In a particle accelerator, electrons are sped up to extremely high speeds and then passed through a series of magnets that make them wiggle. As they wiggle, they release light energy. By tuning the accelerator and the magnets carefully, that light can be produced at the extreme ultraviolet wavelength, which is the type of light semiconductor factories use to etch the tiniest patterns onto silicon wafers.  

This method is different from the current system used by ASML, which relies on firing powerful lasers at droplets of tin to create plasma that emits EUV light. The accelerator approach could be cleaner and more efficient because the EUV light comes directly from the electron beam rather than from a messy plasma process. It also offers the possibility of scaling up power more easily, since accelerators can be designed to produce stronger beams.

The challenge is that particle accelerators are usually very large machines found in physics labs, not compact systems that can fit inside a chip factory. Shrinking them down and making them reliable enough for continuous industrial use is a massive engineering hurdle. That is why xLight’s work is still experimental and why government funding is being directed toward it. If successful, this approach could give the United States its own homegrown EUV technology and reduce reliance on foreign suppliers.

The reason this matters is that chips are the brains inside phones, computers, cars, and even satellites. Whoever controls the tools to make the most advanced chips has a huge advantage in technology and national security. Right now, the United States depends on Europe’s ASML for this critical equipment. By backing xLight, the U.S. hopes to build its own version and reduce reliance on foreign suppliers.

The catch is that xLight’s technology is still experimental. It looks promising, but it hasn’t yet proven it can run reliably in a factory. That’s why the government is investing money: to give xLight a chance to develop and test this new kind of “super‑light bulb” for chipmaking. If it works, it could reshape the global semiconductor industry.

Comparative Table: xLight vs ASML EUV Systems

Feature / Aspect	xLight (Free-Electron Laser Approach)	ASML (Current EUV Laser Systems)
Technology Core	Uses free-electron lasers (FELs), where high-energy electrons generate EUV light directly	Relies on laser-produced plasma (LPP), where a CO₂ laser hits tin droplets to create EUV light
Maturity Level	Experimental / early-stage; still in R&D with high technical risk	Commercially proven; ASML has shipped EUV systems used in advanced chip fabs worldwide
Efficiency	Potential for higher efficiency and more stable EUV output if FEL tech succeeds	Less efficient, requiring massive laser power and complex optics
Scalability	Could enable scalable, modular EUV sources if FELs are miniaturized	Already scaled for mass production, but systems are extremely large and complex
Cost Outlook	High upfront R&D costs; long-term promise of lower operating costs if FELs reduce power needs	Extremely expensive machines (~$200M+ each), with high operating and maintenance costs
Supply Chain Dependence	Aims to create a domestic U.S. alternative, reducing reliance on European suppliers	Dominated by ASML (Netherlands) with critical components from Trumpf (Germany)
Strategic Positioning	Backed by U.S. government funding ($150M) to break ASML’s monopoly and secure national security	Holds a global monopoly on EUV lithography, critical for advanced semiconductor nodes
Risk Factors	Technology risk: FELs are unproven in commercial chipmaking	Market risk: ASML’s dominance creates supply chain bottlenecks, but technology is proven

Key Details

• Funding amount: Up to $150 million in federal incentives.
• Mechanism: A non-binding preliminary letter of intent signed by the Commerce Department.
• Equity stake: The U.S. government will take a stake in xLight, though the size has not been disclosed.
• Strategic importance: This is the first CHIPS R&D award under the Trump administration, signaling a priority shift toward early-stage, high-potential semiconductor technologies.

What xLight Does

• Focus area: xLight is working on free-electron lasers for extreme ultraviolet (EUV) lithography, the critical technology used to etch patterns onto silicon wafers for advanced chips.
• Global competition: Currently, Dutch company ASML dominates EUV lithography, sourcing laser technology from Germany’s Trumpf. xLight aims to create a domestic alternative, reducing reliance on foreign suppliers.
• Leadership: The startup is chaired by Pat Gelsinger, former Intel CEO, adding credibility and industry expertise.

Strategic Implications

• For U.S. semiconductor policy: Reflects the administration’s push to rebuild domestic chipmaking capacity and reduce dependence on foreign technology.
• For industry: If successful, xLight could become a direct competitor to ASML, reshaping the global semiconductor supply chain.
• For geopolitics: Strengthening U.S. control over EUV lithography tools is seen as a national security priority, given their role in advanced computing and AI hardware.

Challenges Ahead

• Technology risk: Free-electron lasers are still experimental compared to ASML’s proven systems.
• Capital intensity: Competing with ASML’s decades of R&D will require sustained funding beyond the initial $150M.
• Global supply chain: Even with domestic innovation, semiconductor manufacturing remains deeply interconnected internationally.

In short: The Trump administration’s $150M bet on xLight is both a strategic gamble and a signal of intent — aiming to break ASML’s monopoly on EUV lithography and bring critical chipmaking technology back under U.S. control.

xLight’s FEL approach is a high‑risk, high‑reward bet that could revolutionize EUV lithography if successful. ASML’s LPP systems are proven but costly and monopolized, making them the current industry standard.
