Couldn't find lead section for EUV_lithography

Extreme ultraviolet lithography (EUVL or simply EUV) is a technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates. As of 2025, ASML is the only company that produces and sells EUV systems for chip production, targeting 5 nanometer (nm) and 3 nm process nodes, though Reuters reported in December 2025 that China had developed its own prototype EUV lithography system,[1] China is also…
