1, IC chip (Integrated Circuit) is a large number of microelectronic components (transistors, resistors, capacitors, etc.) formed integrated circuit on a plastic base, to make a chip. Almost all chips seen today can be called IC chips. 1, the type of integrated circuit is generally classified by the number of electronic components including transistors: SSI(small integrated circuit), the number of transistors 10 ~ 100; MSI(medium integrated circuit), transistor number 100 ~ 1000; LSI(large-scale integrated circuit), transistor number 1000 ~ 100000; VLSI(Very large scale Integrated circuit), transistor number more than 100,000.
Classification by functional structure: Integrated circuits can be divided into two categories: analog integrated circuits and digital integrated circuits according to their functions and structures.
Three, according to the production process classification: integrated circuit according to the production process can be divided into semiconductor integrated circuit and film integrated circuit.
Membrane integrated circuits are classified into thick film integrated circuits and thin film integrated circuits.
Four, according to the conductive type of different classification: integrated circuit according to the conductive type can be divided into bipolar integrated circuit and unipolar integrated circuit.
Bipolar integrated circuit production process is complex, large power consumption, representing the integrated circuit TTL, ECL, HTL, LST-TL, STTL and other types.
The production process of unipolar integrated circuit is simple, the power consumption is also low, and it is easy to make large-scale integrated circuit, which represents the integrated circuit has CMOS, NMOS, PMOS and other types. Classification by use: Integrated circuits can be divided into integrated circuits for television sets by use. Audio integrated circuit, DVD player integrated circuit, video recorder integrated circuit, computer (microcomputer) integrated circuit, electronic organ integrated circuit, communication integrated circuit, camera integrated circuit, remote control integrated circuit, language integrated circuit, alarm integrated circuit and various application-specific integrated circuit.
