## About

Based in the US, xLight Inc. specializes in developing innovative Free Electron Lasers (FELs) to enhance the efficiency of semiconductor manufacturing processes. xLight Inc. is focused on creating advanced Free Electron Laser systems that improve semiconductor production. Founded in 2021, the company is headquartered in Palo Alto, US. It has completed one significant funding deal to date. The founder of xLight has experience in the semiconductor industry, although specific past ventures are not disclosed. In December 2025, xLight Inc. received USD 150 million from new investor Department of Commerce. xLight specializes in the development of advanced Free Electron Lasers (FELs) designed to enhance semiconductor manufacturing through more efficient lithographic patterning. The company's core product offerings include a powerful FEL system that produces up to four times more power than traditional Laser Produced Plasma (LPP) sources, enabling the production of chips with smaller and more efficient feature sizes. This technology meets the growing demands of next-generation lithography, supporting programmable light characteristics that cater to evolving industrial needs. Its target customer base predominantly includes semiconductor fabrication plants (fabs) utilizing ASML scanners, as the xLight system can integrate seamlessly with existing equipment, significantly upgrading performance. xLight's products are marketed towards major semiconductor manufacturing hubs in North America, Europe, and Asia, which are critical for economic growth and national security.xLight's revenue model is built around supplying its advanced FEL systems to semiconductor manufacturers, allowing for significant cost reductions and productivity improvements. Business transactions typically occur through direct B2B partnerships with semiconductor fabs, where xLight provides its systems alongside ongoing support and service agreements. This structure enables clients to optimize their lithographic capabilities while reducing operational costs. Pricing for the systems is based on the scale of installation and the number of ASML scanners supported, with each xLight unit accommodating up to 20 scanners over a 30-year operational lifetime. Furthermore, the company's revenue is enhanced by eliminating consumables such as tin or hydrogen, providing cost savings and improved operational efficiency for clients. The company plans to use the December 2025 to build its first Free-Electron Laser system at a nanotechnology complex and drive domestic lithography innovation beyond current extreme ultraviolet capabilities.
