ASML is the only company that commercially manufactures which advanced chipmaking machines?

ASML is the only company that commercially manufactures extreme ultraviolet, or EUV, lithography machines.

These systems use 13.5-nanometer light to print extremely small patterns on semiconductor wafers. The technology is essential for producing many of the most advanced processors used in artificial intelligence, smartphones, and high-performance computing.

EUV machines are extraordinarily complex. They contain hundreds of thousands of components and use a laser to strike tiny droplets of tin, producing the required plasma light source. ASML developed the systems with a large network of suppliers, including optics specialist Carl Zeiss.

A common mix-up is to call ASML a chip manufacturer. It does not normally fabricate processors itself; it supplies the machinery used by companies such as TSMC, Samsung, and Intel to manufacture chips.
