An integrated circuit (IC) is a kind of miniature electronic device or component. A specific process is used to interconnect the transistors, diodes, resistors, capacitors, and inductors, and other components and wiring required in a circuit, fabricate them on a small or several small semiconductor wafers or dielectric substrates and then encapsulate them in a tube inside the shell, it becomes a microstructure with the required circuit functions; all of the components have been structured as a whole, making the electronic components a big step towards miniaturization, low power consumption, and high reliability. It is represented by the letter "IC" in the circuit. The inventors of integrated circuits are Jack Kilby (silicon-based integrated circuits) and Robert Noyce (germanium-based integrated circuits). Most applications in the semiconductor industry today are silicon-based integrated circuits.
