IC chip (integrated circuit? Chip) is an integrated circuit composed of a large number of microelectronic elements (transistors, resistors, capacitors, etc.). ) on a plastic substrate to make a chip. IC chips include wafer chips and packaging chips, and the corresponding IC chip production line consists of wafer production line and packaging production line.
An integrated circuit is a microelectronic device or element. By adopting a certain process, transistors, diodes, resistors, capacitors, inductors and other components and wiring needed in the circuit are connected together, fabricated on a small piece or several small pieces of semiconductor wafer or dielectric substrate, and then packaged in a package to form a microstructure with the required circuit functions.
All components form a whole in structure, which makes electronic components take a big step towards miniaturization, low power consumption and high reliability. It is represented by the letter "IC" in the circuit.
After the invention and mass production of transistors, various solid-state semiconductor components such as diodes and transistors have been widely used, replacing the functions and functions of vacuum tubes in circuits.
In the middle and late 20th century, the progress of semiconductor manufacturing technology made integrated circuits possible. Compared with the manual assembly of circuits with a single discrete electronic component, integrated circuits can integrate a large number of micro-transistors into a small chip, which is a great progress.
The large-scale production capacity, reliability and modular method of circuit design of integrated circuits ensure the rapid adoption of standardized integrated circuits instead of discrete transistors.
