Apple plans to purchase TSMC’s U.S. factory chips
TSMC’s new fab in Arizona, USA will have to wait nearly two years before it goes into production. It is difficult to judge which chips Apple will choose to produce at the 5nm process node, and how much output is required. Apple may also choose some less important chip orders, such as chips used in earphones or watches, but only if there is a suitable SiP packaging service. In addition, the new Apple TV 4K is already equipped with A15 Bionic, and I believe they will continue to purchase it after two years.
Although there are many speculations in the market, neither Apple nor TSMC has responded to the relevant reports for the time being. After all, the production plan is one of the core business secrets.
