IC It is a miniature electronic device or component that uses a certain process to interconnect components and wirings such as transistors, diodes, resistors, capacitors and inductors required in a circuit, and make them in a small or several small pieces of semiconductor wafers or On a dielectric substrate, and then encapsulated in a package, it becomes a miniature structure with the required circuit functions; in which all components have been structurally integrated, enabling electronic components to move towards miniaturization, low power consumption and high reliability. a big step. Main advantages: low cost and high performance.
