Why is this Dutch company ASML so important and so interesting for all the chip makers in the world? The answer is the very expensive and top EUV (extreme ultra-violet) machine. All the big chip makers (Intel, Samsung, etc.) want this machine. Read again that article given by Ron. For some time now there is (one could think about Huawei, but this is different) an issue: will ASML be allowed to sell that machine to China? There is for example this article at Reuters: Trump administration pressed Dutch hard to cancel China chip-equipment sale: sources There are lots of articles in Dutch media about it, in Dutch, for example: https://nos.nl/artikel/2319073-hoe-...ldhoven-speelbal-werd-van-china-en-de-vs.html https://nos.nl/artikel/2319764-hoe-asml-een-grote-gok-waagde-en-daarmee-monopolist-werd.html No, I do not want to start a political discussion!
