A few days ago, it was reinforced that TSMC would not be building a production facility in the United States, but a report released from the Wall Street Journal contradicts that statement, saying that TSMC is planning to build a facility in Arizona. This would bring the largest independent chipmaker to the United States which could prove to be a huge boost to the development of devices for U.S. based companies. Unnamed sources close to the situation state that this decision was made at Tuesday's board meeting in Taiwan, and has a high likelihood of having a full reveal as soon as this Friday.

This follows suit in the U.S. government's plan to stop TSMC from shipping chips to the Chinese tech giant, Huawei. According to another source, "The State and Commerce Departments are involved in the plans" which further go hand in hand with their plan to interfere with Huawei's supply. The report was not able to find whether TSMC did this under financial incentives. It is suspected that a major reason is being the current shipping times bordering on unbearable for U.S. companies. It also ties into the U.S. worries of Asian technology based upon economics and security that has been affecting them.
