The full name of IC is Integrated Circuit (integrated circuit), it is a technology used to implement circuit functions, to transfer multiple entries in a material processComponentsCombine together to make a singlechip.IC integrated circuits can be understood as a small electronic circuit system with small size, low power consumption,Signal-to-noise ratioHigh-quality, widely used in variousElectronic equipmentamong.

1. What is IC integrated circuit

IC integrated circuits refer to silicon substrates or otherSemiconductor materialsOn the micro-machining process, on the same semiconductorWaferHundreds to hundreds of millions of admiralstransistor,Field effect tube,diode,ResistorsandcapacitanceThe circuit formed by the layout and linking of other components and connection lines according to certain rules contains one or several functional components, which can complete specific functions and are usually usedPackageThe materials are protected for easy connection and use with the outside world.

2. Principles of IC integrated circuits

The production process of IC integrated circuits adopts advanced microelectronics processing technology, that is,Integrated circuit chipA layer of amorphous, polycrystalline or other materials deposited on the surface, photolithography, etching andIon implantationAfter the processing steps, it is formed by a series of processing, lamination and polishing.Circuit diagramshape.On this basis, conductive wires are processed and connected, and the chip is then packaged and processed, thereby realizing the interconnection and protection of circuit components.

3. Function of IC integrated circuits

IC integrated circuits have many advantages, including small size, low power consumption, high reliability, fast working speed and high process accuracy.Therefore, IC integrated circuits are widely used in various electronic devices and systems, such as mobile phones,computer, automobiles, medical instruments,Communication system, aerospace and other fields have brought significant contributions to human production and social development.
