A Brief History of the Lithography Machine: How a Beam of Light Walked Sixty-Nine Years
A Brief History of Lithography: 69 Years of Light
In July 2026, reports of a Chinese state-backed company producing five immersion DUV lithography machines sent shockwaves through Wall Street, wiping roughly $44 billion from ASML's market cap in a single day. This event signaled a crack in the long-held assumption of Western monopoly over advanced chipmaking equipment.
The journey began in 1957 when Jay Lathrop coined the term "photolithography." Early contact aligners (1960s) gave way to PerkinElmer's revolutionary projection aligners in 1973, boosting yields dramatically. GCA's step-and-repeat system (1978) established the modern stepper blueprint. However, within a decade, Japanese firms like Nikon and Canon, supported by a strong domestic market, captured nearly 90% of the global market from American pioneers, who ultimately exited the business.
ASML, founded in a leaky shed in 1984, rose to dominance through key strategic moves: the TWINSCAN dual-stage platform (2001) and the acquisition of SVG, gaining access to Intel. A pivotal moment came in the early 2000s with the industry at a 193nm wavelength impasse. While most invested in the costly 157nm path, TSMC's Burn Lin proposed immersion lithography—using water between the lens and wafer. ASML bet on this simpler idea and, with Zeiss, delivered the first commercial immersion tool in 2004, effectively ending the 157nm roadmap and leaving competitors behind.
The subsequent push for Extreme Ultraviolet (EUV) lithography was an even greater marathon. Deemed the least promising option in 1997, EUV's development, led by ASML, required vacuum chambers, reflective optics, and a complex tin-droplet laser plasma source. Critical to its eventual success (first high-volume manufacturing in 2018) was the 2012 "Customer Co-Investment Program," where Intel, TSMC, and Samsung provided upfront funding and equity, sharing the immense risk and cost.
Today, ASML holds a near-total monopoly in EUV and immersion DUV. The core lesson of this 69-year history is not merely one of technological invention but of sustained partnership. Successive leaders—PerkinElmer, GCA, Nikon—were not ultimately defeated by superior technology but by losing the vital connection to customers willing to tolerate years of iteration, fund long-term R&D, and integrate early, imperfect tools into their production lines. The "light" that completed the journey was always carried by those patient, invested partners.
