One of Apple's most important suppliers is reportedly coming to America

Just a few days ago we passed along a rumor that the Trump administration was talking to Taiwan Semiconductor Manufacturing Co. (TSMC) and Intel about the possibility of the chipmakers building factories in the U.S. to produce cutting-edge chips. Back in March, there was similar speculation that TSMC was actively considering the construction of a facility in the states. That report stated that the Trump administration was pressuring the company to announce before the November election that it was building a fabrication plant in the U.S.
TSMC is trying to get on Trump's good side to prevent him from taking action against the foundry
TSMC is the largest independent foundry in the world and has a client list that contains many of the top names in the smartphone industry. Its largest client is Apple with Huawei second. It also manufactures chips for Qualcomm, MediaTek, and others. These firms design their own chips, but since they don't own fabrication plants, they count on TSMC to roll them off of its assembly line. Today, the Wall Street Journal announced that TSMC is ready to announce the building of a multi-billion dollar facility in Arizona. This comes just as the U.S. says that it would like to stop relying on chips manufactured in Asian countries.

The report says that TSMC could make the announcement as soon as this Friday; the company reportedly held a board meeting yesterday during which it was decided to go ahead with the plans. Previous reports claimed that both the U.S. State and Commerce Departments were involved in the negotiations and this was confirmed by anonymous sources familiar with the situation. The Journal adds that TSMC could start producing chips on U.S. soil starting in 2023 and they will be manufactured using the 5nm process node. This refers to the number of transistors that can fit inside a square mm. The company has recently started manufacturing 5nm chips and the 5G 2020 Apple iPhone 12 family could be the first smartphones to be shipped sporting a 5nm chipset.
Agreeing to build a factory in the states could help TSMC on a couple of fronts, both related to Huawei. The Trump administration wants to require TSMC to obtain an export license from the U.S. before it ships chips to Huawei. These chips are designed using tools made in the U.S. which is why the Trump administration is able to hold it over TSMC's head.
By the time 2023 rolls around, the 5nm chips that TSMC envisions rolling off of its U.S. assembly lines will no longer be cutting-edge. By that year, TSMC could be producing 3nm chips with a transistor density of 300 million transistors per square mm.
