About the Company

ASML

Manufactures photolithography systems for semiconductors

ASML makes photolithography systems for semiconductor manufacturing, focusing on deep ultraviolet (DUV) and extreme ultraviolet (EUV) lithography machines that print circuits on silicon wafers. EUV enables finer features than DUV by using shorter-wavelength light. The company earns revenue from selling the machines and from installation, maintenance, and upgrades, and it differentiates itself by its dominant position in high-end lithography and a global services network serving major chipmakers like TSMC, Samsung, and Intel.
