Earlier quoted context omitted.
Not to mention the people who design many of the machines that TSMC use in their plants: ASML. "The mirrors guiding this light, made of sandwiched layers of silicon and molybdenum, are ground so precisely that, if scaled to the size of Germany, they would have no bumps bigger than a millimetre" https://www.economist.com/business/2020/02/29/how-asml-becam... >
Extremely naive question, but I always wonder how you can "bootstrap" this kind of precision — intuitively for something to be this precise, the tools and equipment that "create" it should also have to be more or less equally precise. Or is it a matter of manufacturing it, testing it, and rejecting some percentage of things that don't fit your requirements due to imprecisions? Are there any good background resources…
