Gelsinger Backs xLight Startup with $150M Commerce Dept. Investment

A year after a tumultuous departure from Intel, Pat Gelsinger has charted a new course, transforming himself from a former chip giant to a venture capitalist. Now, as a general partner at Playground Global, he’s leveraging his deep tech expertise to guide a portfolio of 10 startups. A particularly noteworthy investment has garnered his focused attention: xLight, a semiconductor startup aiming to revolutionize chip manufacturing with a novel approach to lithography. Last Monday, xLight announced a preliminary agreement with the U.S. Commerce Department, securing a $150 million investment that will transform the company into a U.S. government-backed operation. This development underscores Gelsinger’s continued influence within the semiconductor industry and highlights a significant trend – the Trump administration’s deliberate intervention in strategic technological sectors.

xLight: A Bold Gamble on Free Electron Lasers

xLight’s core technology revolves around massive “free electron lasers,” powered by particle accelerators, designed to etch microscopic patterns onto silicon wafers. This approach, if successful at scale, addresses a critical bottleneck in the semiconductor industry – lithography, the process of creating intricate designs on chips. The company’s ambition is ambitious, seeking to double Moore’s Law, the long-standing principle driving computing power’s progress. The planned machines – roughly 100 meters by 50 meters, comparable to a football field – would operate at wavelengths as precise as 2 nanometers, significantly exceeding the 13.5 nanometer wavelengths currently employed by ASML, the dominant player in extreme ultraviolet (EUV) lithography. Approximately half of the investment will be focused on developing this groundbreaking lithography technology.

Government Backing and Strategic Significance

The U.S. Commerce Department’s investment represents the first Chips and Science Act award under Trump’s second term, and it’s being targeted at early-stage companies with promising technologies. Crucially, the government will hold a minority stake in xLight without exerting control or veto rights. This arrangement has sparked debate, with some observers criticizing the administration’s approach as state capitalism. However, Pat Gelsinger views the investment as a necessary component of national competitiveness. “How many nuclear reactors are being built in the US today? Zero. How many being built in China today? 39,” he stated, drawing parallels to the energy sector. “Energy policy in a digital AI economy equals the economic capacity of the nation.” The investment reflects a broader recognition that technological leadership is paramount in the 21st century.

A Novel Approach to Lithography

xLight’s technological leap is facilitated by Nicholas Kelez, the company’s leader, whose background is notably unique within the semiconductor world. Prior to founding xLight, Kelez led quantum computer development efforts at PsiQuantum and spent two decades building large-scale X-ray science facilities at national labs like SLAC and Lawrence Berkeley. This experience, combined with the constraints that ASML placed on similar approaches a decade ago, has proven pivotal. “It just wasn’t the time to take on something completely new and orthogonal,” Kelez explained. However, with ASML’s EUV technology now ubiquitous and existing light sources approaching their limits, the timing for xLight’s “free electron lasers” approach has improved dramatically. The key innovation is treating light like a utility rather than integrating it into each machine – a strategy that, according to Kelez, “constrains you to make it smaller and less powerful."

Collaboration and Strategic Partnerships

xLight is pursuing a collaborative strategy, working closely with ASML and its suppliers, including Zeiss, who provides its optics. This cooperation ensures integration with the existing landscape of the semiconductor industry. Interestingly, xLight has not yet secured commitments from Intel or other major chipmakers, though it’s engaged in intense conversations with them. Despite this, Pat Gelsinger remains optimistic, stating that “Nobody has committed yet, but the work is going on with everybody on the list that you would expect” – a strategy that highlights his belief in the long-term potential of the technology. Adding to the complexity, Substrate, a semiconductor startup backed by Peter Thiel, has recently raised $100 million to develop U.S. chip fabs, including an EUV tool that mirrors xLight’s approach, creating a competitive backdrop.

Gelsinger’s Vision and a Renewed Focus

Pat Gelsinger’s investment in xLight reflects more than just a business decision; it’s a reaffirmation of his vision and a return to a field he knows intimately. He’s managing a diverse portfolio of 10 startups, a significant shift from his previous role at Intel. “I’m a deep tech guy at the core of who I am. My mind is so stretched here, and I’m just grateful that the Playground team would have me to join them and let me make them smarter and be a rookie venture capitalist,” he commented. Adding a personal touch, Gelsinger concluded his involvement by stating, “And I gave my wife back her weekends.” His continued drive and strategic thinking signal a determined force within the global semiconductor landscape.

With xLight poised to commence silicon wafer production by 2028 and achieve its target of an operational system by 2029, Pat Gelsinger’s strategic foray into venture capital demonstrates a commitment to reigniting technological innovation and positioning the U.S. at the forefront of the semiconductor industry. His involvement marks a compelling narrative of resilience, adaptation, and a renewed focus on long-term technological achievement – a story fueled by both profound expertise and a determination to not only find success, but to reshape the competitive landscape.
