In the spring of 2026, Elon Musk unveiled the TeraFab chip manufacturing plan, aiming to meet the immense computing power needs of SpaceX and Tesla. He subsequently signaled a move into the photolithography machine market, with speculation centering on a Free Electron Laser (FEL) approach to challenge the dominance of traditional EUV technology. Currently, ASML, utilizing Laser-Produced Plasma (LPP) EUV光源, holds a near-monopoly. However, LPP faces bottlenecks in energy conversion efficiency, tin debris contamination, and a power ceiling. In contrast, FEL technology, pursued by companies like xLight (where former Intel CEO Pat Gelsinger serves as executive chairman), offers a different path. It generates EUV light by accelerating electrons, potentially providing higher power without plasma conversion and its associated contamination, targeting the sub-13.5nm "beyond-EUV" wavelength range. The photolithography landscape shows three main trajectories: ASML's incremental evolution (like High-NA EUV),光源革新 like FEL targeting ASML's core component, and non-EUV alternatives like Nanoimprint Lithography (NIL) or Electron Beam Lithography (EBL). While ASML remains the dominant player with strong financials and产能 expansion plans, new entrants are challenging the status quo. xLight claims its FEL could boost productivity by 50-100%. Other paths include Substrate's particle-accelerator-based X-ray lithography and Chinese research into LPP alternatives. Musk's TeraFab is a high-stakes bet that FEL can move from lab to fab, that "plug-and-play"光源 replacement can circumvent ASML's ecosystem, and that massive future compute demand justifies a new supply chain. His public endorsement of FEL signifies that the photolithography business is no longer ASML's game alone.
