The silicon wafer is coated with a photoresist such that it dissolves upon exposure to ultraviolet light, which may be accomplished by applying a first shade to cause the portion of the ultraviolet light directed to be dissolved, which dissolved portion may then be washed away with a solvent. The remaining part is then shaped like a shade, which is what we want, and this results in the desired silicon dioxide layer. The wafer is implanted with ions to produce P, N semiconductor, and the wafer is first exposed and then set inside chemical ion mixture liquid. This process will change the electrical mode of the doped regions so that each transistor can be turned on, off, or carry data, a simple chip can use only one layer, but a complex chip usually has many layers, this process is repeated continuously at this time, and the different layers can be connected through an open window, similar to the fabrication principle of the PCB board of the layers.
