Integrated circuits have the advantages of small size, light weight, fewer lead wires and soldering points, long life, high reliability, good performance, etc., and at the same time low cost and convenient for mass production. It is not only widely used in industrial and civilian electronic equipment such as radio recorders, televisions, computers, etc., but also in military affairs, communications, remote control, etc. Using integrated circuits to assemble electronic equipment can increase the assembly density by tens to thousands of times compared with transistors, and the stable working time of equipment can also be greatly improved.
Types of integrated circuit chips
1. Functional structure Integrated circuits, also known as ICs, can be divided into three categories: analog integrated circuits, digital integrated circuits, and digital/analog hybrid integrated circuits according to their functions and structures. Analog integrated circuits, also known as linear circuits, are used to generate, amplify and process various analog signals (referring to signals whose amplitude changes with time. For example, audio signals of semiconductor radios, tape signals of recorders, etc.), and their input signals and output signals are ratio. Digital integrated circuits are used to generate, amplify and process various digital signals (referring to signals with discrete values in time and amplitude. For example, 3G mobile phones, digital cameras, computer CPUs, digital TV logic control and replayed audio signals and video signal).
2. Manufacturing process Integrated circuits can be divided into semiconductor integrated circuits and film integrated circuits according to the manufacturing process. Film integrated circuits are classified into thick film integrated circuits and thin film integrated circuits. 3. The level of integration Integrated circuits can be divided into: SSIC Small Scale Integrated Circuits MSIC (Medium Scale Integrated circuits) LSIC (Large Scale Integrated circuits) VLSIC (Very Large Scale Integrated circuits) ULSIC (Ultra Large Scale Integrated circuits) GSIC gigantic scale integrated circuit is also known as extremely large scale integrated circuit or ultra large scale integrated circuit (Giga Scale IntegraTIon).
