An integrated circuit is simply called an IC. Refers to an advanced microelectronic device that integrates many microelectronic devices on a chip. Silicon-based materials are commonly used on which N-type and P-type semiconductors and P-N junctions are formed by diffusion or infiltration techniques.

An integrated circuit is a semiconductor integrated circuit, that is, a semiconductor material is used as a substrate, and at least one of two or more components of the active component and some or all of the interconnections are integrated in the substrate or on the substrate to perform a certain An intermediate or final product of electronic functions;

The types of integrated circuits are generally classified by the number of electronic components such as transistors.

· SSI (small integrated circuit), number of transistors 10~100

· MSI (Medium-sized Integrated Circuit), transistor number 100~1,000

· LSI (Large Scale Integrated Circuit), the number of transistors is 1,000~10,0000

· VLSI (Very Large Scale Integrated Circuit), transistor number 100,000~

There are many types according to usage, such as audio integrated circuits, music integrated circuits, operational amplifier integrated circuits, decoding integrated circuits, TV small signal integrated circuits, microprocessor integrated circuits.
