The company had no choice but to rely on a single source for the key components of an EUV system. To manage this, ASML drilled down into its suppliers’ suppliers to understand the risks. ASML rewarded certain suppliers with investment, like the $1 billion it paid Zeiss in 2016 to fund that company’s R&D process. It held all of them, however, to exacting standards. “If you don’t behave, we’re going to buy you,” ASML’s CEO Peter Wennink told one supplier. It wasn’t a joke: ASML ended up buying several suppliers, including Cymer, after concluding it could better manage them itself.
