What xLight does
xLight is a privately held deep-technology company founded in 2021 and headquartered in Palo Alto, California, developing particle accelerator-driven Free Electron Laser (FEL) systems intended to replace incumbent Laser Produced Plasma (LPP) sources for Extreme Ultraviolet (EUV) lithography in advanced semiconductor manufacturing. The company's core technology builds on superconducting radio-frequency accelerator and undulator physics refined over decades at U.S. Department of Energy national laboratories, accelerating electrons through RF and magnetic fields to produce coherent, high-intensity EUV light. Engineering and R&D operations are distributed across Palo Alto (corporate headquarters), the Albany Nanotech Complex in New York (prototype construction), Newport News, Virginia (accelerator and beamline systems), and New Mexico (Los Alamos collaboration).
xLight's single core product is a utility-scale FEL system designed to deliver EUV light to an entire semiconductor fabrication facility from a centralized source, supporting up to 16 lithography scanners simultaneously. Company-stated performance targets include 4X the EUV power of current LPP sources, 50% lower EUV cost per wafer, 20% lower total wafer cost, elimination of consumables such as tin and hydrogen, and programmable tunable light enabling sub-2nm process nodes. The first prototype is being built at Albany Nanotech, with demonstration on current-generation EUV lithography machines targeted for 2028.
The business model is direct enterprise hardware sales and long-term service contracts to leading-edge semiconductor fabs and foundries — TSMC, Samsung, Intel, and GlobalFoundries are named target customers — coordinated technically with lithography tool makers such as ASML. The company is pre-revenue and has funded operations to date through approximately $11 million in early venture capital, a $40 million Series B round led by Playground Global (July 2025), and a $150 million CHIPS and Science Act award finalized in June 2026 in which the U.S. Department of Commerce took a minority equity stake. Leadership includes Nicholas Kelez (CEO/CTO, ex-SLAC and PsiQuantum), Pat Gelsinger (Executive Chairman, former CEO of Intel and VMware), and an advisory board drawing from GlobalFoundries, ASML, Applied Materials, Intel, and several DOE national laboratories.

xLight product offering
Product offeringCore offering
xLight builds Free Electron Laser (FEL) systems that generate Extreme Ultraviolet (EUV) light for advanced semiconductor lithography. The FEL system is deployed outside the fab and delivers high-power EUV light as a centralized, utility-scale service capable of powering up to 16 lithography scanners simultaneously, replacing today's per-tool Laser Produced Plasma (LPP) light sources. Revenue is generated through sale or lease of the FEL hardware, installation, and long-term service agreements with leading-edge semiconductor manufacturers and foundries.
Product overview
xLight offers a single unified core product: its Free Electron Laser (FEL) system for EUV lithography in semiconductor manufacturing. The FEL system is built outside the semiconductor fab and delivers EUV light as a utility-scale service, fundamentally transforming how light is delivered to fabs — from individual tool-level light sources to a centralized utility that can power multiple lithography scanners simultaneously.

xLight competitors and assessment
Company assessmentBroad incumbents
- ASML: ASML is the dominant EUV lithography systems manufacturer and currently integrates Laser Produced Plasma (LPP) light sources into its scanners. While xLight positions itself as a complementary light-source supplier (not a scanner competitor), ASML is the central counterpart in xLight's go-to-market and the most direct strategic peer given the EUV value chain overlap.
- Coherent: Coherent is a major laser systems manufacturer serving semiconductor, materials processing, and scientific markets. As a broad laser industry incumbent, Coherent is a comparable large-scale photonics business and potential competitor if it expands into EUV-source-class laser systems.
- Mitsubishi Electric (Power Device Works / Laser): Mitsubishi Electric manufactures CO2 lasers used in EUV light source systems and is a competitor in the laser-based semiconductor equipment space. As a broad industrial electronics and laser incumbent, it is an adjacent peer to xLight's EUV light source business.
Direct peers
- Trumpf: Trumpf manufactures the high-power CO2 lasers that drive the Laser Produced Plasma (LPP) EUV sources used in ASML's current systems. As the incumbent supplier of laser-based EUV light source components, Trumpf is the most direct functional competitor to xLight's FEL approach.
- Gigaphoton: Gigaphoton is the only other commercial supplier of LPP EUV light sources and a direct technology competitor to xLight in delivering EUV light to semiconductor fabs. Their incumbent position with major fabs makes them xLight's primary head-to-head rival for next-generation EUV source business.
Emerging players
- Lyncean Technologies: Lyncean Technologies develops compact Free Electron Laser (FEL) systems for scientific and industrial applications. As one of the few commercial FEL developers, Lyncean is the closest emerging technology peer to xLight, though focused on smaller-scale applications rather than EUV lithography.
- RadiaBeam Technologies: RadiaBeam develops particle accelerator and beamline technology with applications spanning science, industry, and security. They share xLight's accelerator physics DNA and represent an emerging peer in commercializing accelerator-derived systems, though not focused on EUV lithography.
- Euclid TechLabs: Euclid TechLabs develops advanced accelerator and beam physics components, including undulators and beam diagnostics — direct technological building blocks of FEL systems. They are an enabling/adjacent peer in the FEL value chain.
- Hamamatsu Photonics: Hamamatsu Photonics develops photonics and optoelectronic components including light sources, detectors, and imaging systems used in semiconductor and scientific applications. They are an adjacent peer in advanced photonics with potential overlap in EUV-adjacent technologies.
Others
- Advanced Energy Industries: Advanced Energy provides precision power conversion and RF power systems used across semiconductor manufacturing equipment, including EUV systems. While not a light-source peer, AE is a comparable enabling supplier to the semiconductor capital equipment ecosystem where xLight operates.
