An integrated circuit (represented by the letter IC in a circuit) is a miniature electronic device or component. By adopting a certain process, the components such as a transistor, a resistor, a capacitor, an inductor and the like required in a circuit are interconnected together with wiring, are manufactured on one or more small semiconductor wafers or dielectric substrates, and are then packaged in a tube shell to form a microstructure with the required circuit function; All the components have been integrated into a whole in structure, which makes the electronic components take a big step towards miniaturization, low power consumption, intelligence and high reliability.
