They are trying, although not there yet. There is also the capacity issue: TSMC has 28% of the semiconductor market under 40nm, Samsung has 10%. As a foundry, it's ~55% vs ~17%. Add in UMC and a few others and it's 64% Taiwan. Definitely a critical dependency. https://www.notebookcheck.net/TSMC-has-the-largest-market-share-in-the-global-semiconductor-manufacturing-industry-Counterpoints-Research.518137.0.html https://www.notebookcheck.net/TSMC-has-the-largest-market-sh... https://www.eenewsanalog.com/news/foundry-market-jumps-24-percent-2020 https://www.eenewsanalog.com/news/foundry-market-jumps-24-pe...
