No, mainstream Intel processors will have 2 billion transistors, high-end products can reach 6 billion, one link method is not practical, so the use of optical etching technology.The process of photoetching is to use a certain wavelength of light to carve a corresponding notch in the sensitive layer, thereby changing the chemical properties of the material there.The technique is extremely strict about the wavelength of light used, requiring the use of short wavelengths of ultraviolet light and lenses of large curvature.The etching process is also affected by stains on the wafer.Each step of etching is a complex and delicate process.The amount of data required to design each step of the process can be measured in 10GB units, and the etching steps required to manufacture each processor are more than 20 steps (one layer at a time).And each layer of etched drawings, if magnified many times, can be compared with the whole of New York City and the suburbs, and even more complex.When the etching is complete, the wafer is turned upside down.Short-wavelength light shines through the hollowed marks in the quartz template to the sensitive layer of the wafer, and then the light and the template are removed.The exposed photosensitive layer is chemically removed, and silica is immediately formed beneath the empty space.

We need a lithography machine.

Of course, the chip CPU of the PC machine also needs a photolithography machine, and the computer chip itself is a semiconductor component, and silicon wafers are made through the photolithography mechanism. Both the mobile device chip and the computer chip are silicon-based semiconductors, the physical structure is the same, but the design architecture is different.
