Integrated circuit (integrated circuit) is a kind of miniature electronic device or component. A certain process is used to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit, fabricate on a small or several small semiconductor wafers or dielectric substrates, and then package them in a package , It has become a micro structure with the required circuit functions; all of the components have been structured as a whole, making electronic components a big step towards micro miniaturization, low power consumption, intelligence and high reliability.
