TSMC is really the keystone for everything else done that ends up getting talked about on this website. They are constantly at the bleeding edge of computer manufacture and pushing it further still. We should feel some sense of amazement to be alive still in the middle of the computer revolution.
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... >
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 on how some of these things are done?
