The twenty-first century is the age of digital communication. Such rapid development of digital information largely depended on the development of IC chips.
IC chips combined the transistors, resistors, capacitors, inductors, and other components and wiring required in a circuit, all fabricated on one or several small semiconductor chips. The smaller they could be manufactured, the more of them could be arranged together which led to greater processing speed.
Therefore, the development of IC chips was in essence, the miniaturization of integrated circuits.
The so-called lithography machine played a crucial role in the manufacturing process of computer chips. It utilized light sources of various wavelengths to execute the printing process using lithography, allowing it to manufacture chips.
