I've long appreciated ASML Holding N.V.'s dominant position in the semiconductor lithography market. The company commands over 90% share in advanced deep ultraviolet (DUV) immersion systems and 100% in EUV lithography—the critical technology for chips below 7nm nodes used in AI, high-performance computing, and memory. This near-monopoly comes from decades of R&D investment, exclusive partnerships like Zeiss for optics, and a vast installed base that generates steady service revenue. From what I see, competitors such as Nikon and Canon remain far behind in EUV, sticking to mature nodes.
