This US dependence on TSMC's Taiwanese factories will only end if the US government give around US$100 billion to GlobalFoundries to it build a gigantic chip factory on US soil, using the most modern machinery from ASML.
Until the US government does not do exactly that, the "CHIPS and Science Act" will be of little use and the US will continue to be riskily dependent on TSMC's factories in Taiwan.
And of course, this giant GlobalFoundries factory on US soil would also have to encompass not only the lithography process, but also all the subsequent steps necessary until the chips are ready for use by OEMs and domestic customers.
And a gigantic factory like this on American soil would generate millions of direct and indirect jobs, in addition to being able to provide and receive support to/from US research centers.
I only showed the central idea in my previous post. The US government has to have a giant chip factory built on American soil with cutting-edge machinery as soon as it starts operating, since cutting-edge machinery, in about 2 years, will no longer be cutting-edge and can be used to manufacture cheaper chips that do not require such advanced lithography.
And this factory, in addition to having all the necessary steps before and after the lithography process on American soil, has to be independent: it cannot manufacture chips for itself, like Intel. Many other companies do not want to hire Intel as a chip manufacturer because Intel would manufacture and have access to the chip designs of its direct competitors well in advance, even if they are protected by patents. If, for example, Nvidia were to hire Intel to manufacture GPUs for it, Nvidia would show many of its industrial secrets to Intel, which is its competitor. And the same would happen to many other companies, since Intel manufactures several types of chips and, therefore, is a competitor of many other companies.
The entire US government (executive, legislative and judicial branches of the US) would have to come together and take drastic measures to build this mega chip factory on American soil. They could, for example, contact Bill Gates and other major investors so that they would buy GlobalFoundries and transform it into a 100% American company. And then, the US government would have to hand over around US$100 billion so that this giant factory could be built in the US.
Until the US government finds a way to have this giant chip factory built on US soil, the US will suffer drastically if country X invades, occupies and takes over the factories of country Y.
That's the main idea. Everyone can draw their own conclusions.
