The chip is nano, and the mobile phone chip is closely related to the nano process. Nanometer is actually the millimeter, is a unit of length, the symbol of the international unit is nm. In popular terms, like the well-known Apple A15 bionic chip is 5 nm, Tianguet 9000 and Snapdragon 8 chips are 5 nm, but the latest mobile phone chip production process has come to 4 nm, which is about to meet you in the second half of the year, Apple A16 chip, Qualcomm Snapdragon 8 chip and Tianguet 9000 chip. Intuitively, it should be that the smaller the number of nanometers, the stronger the chip performance.
Nanometer, the chip is made with a lithography machine, and the most advanced lithography machine is a five-nanometer process
