A ‘sliding doors’ moment 20 years ago set photolithography specialist ASML on the path to becoming one of Europe’s most successful technology companies and a key player in the global semiconductor supply chain. As the resolution limits of photolithography technology – the printing process used to make semiconductors – started to come into the view at the turn of the millennium, ASML and Nikon, at the time the two leading companies in the sector, began to think about the future. “Nikon and ASML pursued different paths for what was to come next,” explains Dr Chris Mack, a photolithography expert and adjunct faculty member at the University of Texas. “Nikon pursued a path called electron beam (EB) photolithography, while ASML pursued a path called extreme UV (EUV) photolithography.”    It turned out ASML picked ...
