Mobile phone chip nm means the width of the minimum structure of the chip.
Mobile phone chip nm is the meaning of nano, nano is a unit of length, 1nm is about a hair cross section of 1\/60,000th of the length. The inside of the mobile phone chip is composed of billions of silicon transistors, and the width of each transistor is the nm process of the mobile phone chip, such as 7nm, 5nm and even the latest 4nm.
nm is nanometer, length unit, the chips on the market are nano, the best chip is 5nm process, that is, the width of the transistor (also called line width) is 5nm, then how big is 5nm? It is to cut a hair into 10,000 strands, one of which has a diameter of 5nm.
