The working principle of integrated circuits (composition and package form of integrated circuits)

First, what is an integrated circuit
Integrated circuit, English is IntegratedCircuit, abbreviated as IC; as the name suggests, is a certain number of commonly used electronic components, such as resistors, capacitors, transistors, etc., and the connection between these components, through the semiconductor process integrated with specific functions Circuit.
Second, the classification of integrated circuits
1, functional structure

Integrated circuits, also known as ICs, can be classified into 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 amplitude-varying signals over time, such as audio signals from semiconductor radios, tape signals from recorders, etc.), and their input and output signals are ratio. Digital integrated circuits are used to generate, amplify, and process a variety of digital signals (referred to as discrete signals in time and amplitude. For example, 3G mobile phones, digital cameras, computer CPUs, digital TV logic control and playback of audio signals) And video signals).

2, the production process

The integrated circuit can be classified into a semiconductor integrated circuit and a film integrated circuit according to a manufacturing process.

Membrane integrated circuits are also classified into thick film integrated circuits and thin film integrated circuits.

3, the level of integration

Integrated circuits can be divided into different levels of integration:

SSIC Small Scale Integrated Circuits (SmallScaleIntegrated Circuits)

MSIC medium scale integrated circuits (MediumScaleIntegratedcircuits)

LSIC Large Scale Integrated Circuits (LargeScaleIntegrated Circuits)

VLSIC Very Large Scale Integrated Circuits (VeryLargeScaleIntegratedcircuits)

ULSIC Large Scale Integrated Circuits (UltraLargeScaleIntegrated Circuits)

The GSIC giant scale integrated circuit is also known as a very large scale integrated circuit or a very large scale integrated circuit (GigaScaleIntegraTIon).

4, different conductivity types

Integrated circuits can be classified into bipolar integrated circuits and unipolar integrated circuits according to the type of conductivity, and they are all digital integrated circuits.

The bipolar integrated circuit has a complicated manufacturing process and a large power consumption, and represents an integrated circuit having TTL, ECL, HTL, LST-TL, STTL, and the like. The unipolar integrated circuit has a simple manufacturing process and low power consumption, and is easy to be made into a large-scale integrated circuit. The representative integrated circuit has CMOS, NMOS, PMOS and the like.

5, according to use

Integrated circuits can be classified into integrated circuits for televisions, integrated circuits for audio, integrated circuits for video players, integrated circuits for video recorders, integrated circuits for computers (microcomputers), integrated circuits for electronic keyboards, integrated circuits for communication, and integration of cameras. Circuits, remote control integrated circuits, language integrated circuits, integrated circuits for alarms, and various application specific integrated circuits.

6, according to the application area

Integrated circuits can be classified into standard general-purpose integrated circuits and application-specific integrated circuits according to the application field.

7, according to the shape

The integrated circuit can be divided into a circular shape (a metal case transistor package type, generally suitable for high power), a flat type (good stability, small size), and a dual in-line type.
