Uh huh…
TSMC is literally a Taiwan-sponsored company. Its the Taiwanese Semiconductor Manufacturing Company. They’re 100% full bred Taiwanese executives, engineers, and scientists. Their literal geopolitical aim is the “Silicon Shield”, the creation of such companies and processes to encourage other entities (like USA) to defend them.
There’s a reason why AMD, Intel, NVidia, Apple, Samsung, and Qualcomm (aka: Snapdragon aka Android’s #1 chip) are all made in TSMC aka Taiwan. Because they got better manufacturing technology than us. We literally cannot replicate their feats of production.
IE: Yields (percentage of completed chips without errors), costs, production node advancements (3nm vs 2nm), etc. etc.
iPhone chips M1. NVidia RTX 4080. AMD 7800 XTX.
Advanced FPGAs like Xilinx FPGAs used in the F-35 project.
USA literally can’t make these chips. We design them, but only Taiwan has the advanced process nodes to actually make them physically. We send our designs to Taiwan, and they ship them back to us by boat.
Intel literally cannot make these chips in its Arizona, Texas, or Utah fabrication labs. Literally cannot make them. That’s why Intel contracted TSMC to make the Intel Alchemist chips (!!!). The other major advanced manufacturer, Global Foundries (Buffalo, New York) failed 10 years ago and cannot make anything more advanced than 12nm nodes (roughly Taiwan’s 2016 era technology). USA advancement of chips stalled out a decade ago, we rely almost entirely on Taiwan…
Except for the few chips we’re contracting out to Samsung instead, since Korea is the other place who can take these chip orders.
Which is all foundry investment. None of the technology needed belongs to Taiwan. Intel is ramping up for Intel 3 and are already doing high volume production on the Intel 4 using EUV.
Foundries are extremely expensive and everyone was happy to let Taiwan do the whole thing. Now with the geopolitical risk, investment is ramping up into chip foundries again. Once that is done the manufacturing will be mostly on par. Which is completely different to your first post about wizards and no one else can do it nonsense.
We are however going around in circles so I’ll likely leave it here.
