ASML is such an undisputed leader in today’s chip ecosystem that it’s hard to believe the company’s market dominance really only dates back to 2017, when its EUV machine, after 17 years of development, upended the conventional process for making chips.
It’s also a testament to ASML’s dominance that it is for the most part no longer allowed to sell its most advanced systems to customers in China. Though ASML still does business in China, in 2019, following pressure from the Trump administration, the Dutch government began imposing restrictions on ASML’s exports of EUV machines to China. Those rules were tightened further just last year and now also impose limits on some of the company’s deep-ultraviolet (DUV) machines, which are used to make less highly advanced chips than EUV systems.
Yet although today everyone is banking on ASML to keep pushing the industry forward, there is speculation that a competitor could emerge from China. Van den Brink was dismissive of this possibility, citing the gap in even last-generation lithography.
“SMEE are making DUV machines, or at least claim they can,” he told MIT Technology Review, referring to a company that makes the predecessor to EUV lithography technology, and pointed out that ASML still has the dominant market share. The political pressures could mean more progress for China. But getting to the level of complexity involved in ASML’s suite of machines, with low, high, and hyper NA is another matter, he says: “I feel quite comfortable that this will be a long time before they can copy that.”
A continent could be a single landmass or a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents.
