What is ic and what industry is it?

An integrated circuit is a microelectronic device or element. Using a certain process, the components and wiring needed in the circuit are connected together, made on a small piece or several small pieces of semiconductor wafer or dielectric substrate, and then packaged in a package to form a microstructure with the required circuit function; All the components are integrated in structure, which makes electronic components take a big step towards miniaturization, low power consumption, intelligence and high reliability.

An integrated circuit is represented by the letter "IC" in the circuit. Inventors of integrated circuits are jack kilby (Ge-based integrated circuits) and robert noyce (Si-based integrated circuits). Today, most applications in the semiconductor industry are silicon-based integrated circuits.

Extended data:

According to different functions and structures, integrated circuits can be divided into three categories: analog integrated circuits, digital integrated circuits and mixed-signal integrated circuits.

Analog integrated circuits, also known as linear circuits, are used to generate, amplify and process various analog signals (signals whose amplitude varies with time). Such as audio signals of transistor radios, tape signals of tape recorders, etc. ), its input signal is proportional to its output signal. Digital integrated circuits are used to generate, amplify and process various digital signals (signals with discrete values in time and amplitude). For example, the logic control and playback of audio and video signals of 5G mobile phones, digital cameras, computer CPU and digital TV).
