What is EUV lithography and why does it matter for semiconductors?

About semiconductors

Direct answer

Extreme Ultraviolet (EUV) lithography is a chip manufacturing technology that uses 13.5nm wavelength light to etch transistor patterns onto silicon wafers at resolutions previously impossible, enabling the production of sub-7nm chips that power modern AI, mobile, and high-performance computing. It matters because without EUV, chipmakers cannot economically continue shrinking transistors — the foundational principle of Moore's Law — meaning AI accelerators, advanced CPUs, and next-generation mobile processors all depend on EUV for their performance and efficiency gains. ASML Holding is the sole supplier of EUV machines globally, making it a critical chokepoint in the entire semiconductor supply chain. A single EUV system costs approximately $150–$200 million, and high-NA EUV systems (the next generation) exceed $350 million per unit.

Key Takeaways

  • ASML is the world's only manufacturer of EUV lithography machines, giving it an effective monopoly over the most critical tool in advanced chip manufacturing
  • EUV uses 13.5nm wavelength light — roughly 14x shorter than the 193nm deep-ultraviolet (DUV) light used previously — enabling dramatically finer circuit patterns
  • TSMC, Samsung, and Intel all require EUV to produce leading-edge nodes at 7nm and below, including 5nm, 3nm, and 2nm process generations
  • The U.S. government has pressured the Netherlands to restrict ASML's EUV exports to China, making the technology a central front in the U.S.-China semiconductor technology war
  • High-NA EUV (0.55 numerical aperture vs. current 0.33 NA) is the next generation, offering even finer resolution and is critical for sub-2nm nodes expected mid-decade
  • Each EUV machine contains over 100,000 parts and requires 40 shipping containers to transport, illustrating the extreme complexity of the supply chain
  • TSMC manufactures virtually all of the world's most advanced EUV-based chips, producing chips for Apple, NVIDIA, AMD, and Qualcomm at its facilities in Taiwan

Evidence & Analysis

  • ASML shipped 53 EUV systems in 2023, with each standard EUV (Low-NA) machine priced at approximately $150–$200 million
  • ASML's first High-NA EUV system (TWINSCAN EXE:5000) was delivered to Intel in 2023 at a reported price exceeding $350 million per unit
  • TSMC's 3nm process (N3) is entirely dependent on EUV lithography and began high-volume production in late 2022 for Apple A17 Pro chips
  • Without EUV, chipmakers would require 5+ patterning passes using older DUV multi-patterning techniques, dramatically increasing cost, time, and defect rates
  • The U.S. Commerce Department, working with the Dutch government, blocked ASML from shipping EUV tools to Chinese customers beginning in 2023, reflecting the technology's strategic importance
  • ASML held a total EUV installed base of over 140 systems worldwide as of end-2022, with cumulative revenue from EUV representing the majority of its €27.6 billion in 2023 revenue
