It is the United States, which has absolute technological advantages in the field of chips, but does not produce chips, and just designs chips like China. The United States has a leading position in the world in chip materials, photoresist and light source of lithography machines. Taiwan Taiwan Semiconductor Manufacturing Co., Ltd. of China is at the forefront of the world in chip foundry, producing high-end chips for Apple, Huawei and Gaotong successively. But TSMC is also dependent on American technical support.
The United States, whether it is Apple, intel or AMD is an American company!
