The mainstream has 4 nm, 5 nm, 7 nm and other sizes.
At present, the mainstream chip is 4 nm, 5 nm, 7 nm, 10 nm and other sizes. In fact, the chip is not measured by size, and the conventional process is mainly to describe the chip process, that is, the nano process. The smaller the nanoscale process of the chip, the more advanced its performance. If you have to say size, take smart phone chips as an example, basically around 100 square millimeters. Chips used in other industries are not too bad, basically floating in the range of tens of square millimeters to 500 square millimeters.
