The role of IC integrated circuit is to use a semiconductor process or thin, thick film process (or a combination of these processes), the active components of the circuit, passive components and their interconnection wiring are made together on a semiconductor or insulating substrate, and the structure forms a closely linked overall circuit.
Compared with the discrete bulk circuit, the integrated circuit greatly reduces the volume, weight, the number of lead lines and welding points, improves the circuit performance and reliability, reduces the cost, and is convenient for mass production.
From discrete components to integrated circuits, it is a leap in the development of semiconductor electronic technology. Integrated circuit in civil electronic equipment, industrial electronic equipment. Military electronic equipment has a wide range of important applications.
