What is ic?

The full English name of ic is "Integrated Circuit Chip" which refers to IC chip.

IC chip (Integrated Circuit Chip) is an integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) placed on a plastic base to make a chip. IC chips include wafer chips and packaging chips. The corresponding IC chip production line consists of a wafer production line and a packaging production line.

1. According to the number of microelectronic devices integrated on a chip, integrated circuits can be divided into the following categories :

Small integrated circuit (SSI’s full name in English is Small Scale Integration) has less than 10 logic gates or less than 100 transistors.

Medium Scale Integrated Circuit (MSI full name in English is Medium Scale Integration) has 11~100 logic gates or 101~1k transistors.

Large Scale Integrated Circuit (LSI’s full name in English is Large Scale Integration) has 101~1k logic gates or 1,001~10k transistors.

Very large scale integrated circuit (VLSI’s full name in English is Very large scale integration) has 1,001~10k logic gates or 10,001~100k transistors.

Ultra Large Scale Integrated Circuit (ULSI full name in English is Ultra Large Scale Integration) has 10,001~1M logic gates or 100,001~10M transistors.

GLSI (full name in English is Giga Scale Integration) has more than 1,000,001 logic gates or more than 10,000,001 transistors.

2. Classification by functional structure: Integrated circuits can be divided into two categories: analog integrated circuits and digital integrated circuits according to their different functions and structures.

3. Classification by manufacturing process: Integrated circuits can be divided into monolithic integrated circuits and hybrid integrated circuits according to the manufacturing process. Hybrid integrated circuits are divided into thick film integrated circuits and thin film integrated circuits.

4. Classification according to conductivity type: Integrated circuits can be divided into bipolar integrated circuits and unipolar integrated circuits according to conductivity type. The manufacturing process of bipolar integrated circuits is complex and the power consumption is large. Representative integrated circuits include TTL, ECL, HTL, LST-TL, STTL and other types. The manufacturing process of unipolar integrated circuits is simple and the power consumption is low, making it easy to make large-scale integrated circuits. Representative integrated circuits include CMOS, NMOS, PMOS and other types.

5. Classification by use: Integrated circuits can be divided into integrated circuits for televisions, integrated circuits for audio, integrated circuits for DVD players, integrated circuits for video recorders, integrated circuits for computers (microcomputers), and electronic keyboards. Application integrated circuits, communication integrated circuits, camera integrated circuits, remote control integrated circuits, language integrated circuits, alarm integrated circuits and various special purpose integrated circuits.
