IC chip, English name Integrated Circuit Chip (integrated circuit), is an integrated circuit formed by a large number of microelectronic components (resistors, capacitors, transistors, etc.) on a plastic base to make a chip.
IC chips are widely used in the electronics and computer industries. At present, there are many names for IC chips. The common names in China are integrated circuit, IC, chip, and chip. Although the names are different, they all refer to the same one. thing.
Since there are many types of IC chips, and the actual environment is not the same, the classification of IC chips is also vague. However, as far as the classification and division generally accepted by the industry is concerned, it is mainly divided into the following categories.
1. According to the number of electronic components, it can be divided into:
SSI (Small Integrated Circuit): 10 to 100 transistors;
MSI (medium-sized integrated circuit): 100 to 1000 transistors;
LSI (Large Scale Integrated Circuit): 1,000 to 100,000 transistors;
VLSI (Very Large Scale Integration): More than 100,000 transistors.
2. According to the functional structure, it can be divided into:
Analog integrated circuits, digital integrated circuits, analog and digital hybrid circuits, radio frequency integrated circuits, power device / optoelectronic device circuits, sensors and microcomputer system integrated circuits.
3. According to the production process classification, it can be divided into:
Semiconductor integrated circuits and film integrated circuits, wherein film integrated circuits are further classified into thick film integrated circuits and thin film integrated circuits.
4. According to the application scenarios, it can be divided into:
Civilian grade (consumer grade), industrial grade, automotive grade, military grade and other four categories.
5. According to the different types of conductivity, it can be divided into:
Bipolar integrated circuits and unipolar integrated circuits, among which bipolar integrated circuits have complex manufacturing processes and high power consumption, which represent integrated circuits of TTL, ECL, HTL, LST-TL, STTL and other types; and unipolar integrated circuits The manufacturing process of integrated circuits is simple, the power consumption is also low, and it is easy to make large-scale integrated circuits.
