Cell phone chips are not superconductors.
Cell phone chips are semiconductors. The raw material of the mobile phone chip is a wafer, and the wafer is composed of silicon components, so the mobile phone chip is mainly composed of silicon. First, the silicon raw material is purified and turned into a large silicon ingot that is solid after high temperature.
Secondly, the silicon ingot is cut into slices, and then the corresponding substance is added, and then the transistor circuit is painted on the slice, in order to form a nanoscale silicon dioxide film on the surface of the slice, a layer of photosensitive layer is laid on the film, and it is baked in a high temperature oven.
The information layers of each layer are also electrically connected and made into a three-dimensional structure. The complete process of chip production includes chip design, production, packaging, testing and other links, and the chip production link is also very complex.
4G chips are generally semiconductors 5G chips are currently in the experimental stage, and a few are superconductors
Cell phone chips are not superconductors, they are made of semiconductor materials.
