About Integrated circuit

An integrated circuit is an electronic component in which circuits are concentrated and mounted. In English, it is sometimes called Integrated Circuit, or IC as its abbreviation. An electronic circuit in which a large number of electronic elements with various functions are assembled on a single semiconductor substrate and interconnected with internal wiring to perform a predetermined function. A circuit consists of multiple circuit elements and wires that connect them. This circuit element mainly refers to resistors, capacitors, transistors, etc. The degree of integration is increased by manufacturing all of these elements and wiring on a single substrate (chip). ICs are used in every electronic product in the world. Thanks to the miniaturization of ICs, we are able to use small and convenient products such as smartphones. Large-scale ICs with 100,000 to 10,000,000 elements are called LSI (Large Scale Integrated). Until the development of integrated circuits, each electronic element (resistor, diode, capacitor, transistor) had to be mounted individually on a printed circuit board and connected with external wiring. On the other hand, in a popular semiconductor cycle circuit, capacitors, resistors, etc. (passive elements), diodes, transistors, etc. (active elements) are placed on a single-crystal silicon semiconductor substrate and connected to each other by internal wiring. increase. Compared to the age of ore radios, the size has been reduced to less than 1/30,000 in dimensions and less than 1/1,000,000,000 in area.
