(1) The types of integrated circuits are generally classified by the number of electronic components such as transistors

SSI (Small Integrated Circuit), the number of transistors is 10 to 100

MSI (medium-sized integrated circuit), the number of transistors is 100 to 1000

LSI (Large Scale Integration), the number of transistors is 1,000 to 100,000

VLSI (Very Large Scale Integration), with more than 100,000 transistors.

(2) Classification according to functional structure

 
Integrated circuits can be divided into two categories: analog integrated circuits and digital integrated circuits according to their functions and structures.

(3) Classification by production 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.

(4) Classification according to different conductivity types

Integrated circuits can be divided into bipolar integrated circuits and unipolar integrated circuits according to the conductivity type. The manufacturing process of bipolar integrated circuits is complicated, and the power consumption is relatively large. Representative integrated circuits include TTL, ECL, HTL, LST-TL, STTL and other types.

The manufacturing process of unipolar integrated circuits is simple, the power consumption is also low, and it is easy to make large-scale integrated circuits. Representative integrated circuits include CMOS, NMOS, PMOS and other types.

(5) Classification by IC Chip Application

Integrated circuits can be divided into integrated circuits for televisions according to their applications. Integrated circuits for audio, integrated circuits for DVD players, integrated circuits for video recorders, integrated circuits for computers (microcomputers), integrated circuits for electronic organs, integrated circuits for communications, integrated circuits for cameras, integrated circuits for remote control, integrated circuits for language, integrated circuits for alarms circuits and various ASICs.
