Introduction
ASML is a leader in lithography systems, holding a 90% market share in semiconductor manufacturing. Lithography is the process of using a light source to expose circuit patterns from a photomask onto a semiconductor wafer. Lithography allows chip manufacturers to increase the number of transistors on the same silicon area, and historically, it has represented a significant portion of the cost of manufacturing cutting-edge chips. ASML outsources the manufacturing of most components, acting as an assembler. ASML's largest customers include TSMC, Samsung, Intel, SK Hynix, and Micron.
