An integrated circuit (integrated circuit) is a miniature electronic device or component. Using a certain process, the transistor required in a circuit, resistors, capacitors and inductors and other components and wiring interconnect, produced in a small piece or a few small pieces of semiconductor wafer or dielectric substrate, and then encapsulated in a shell, become a required circuit function of the micro-structure, where all the components in the structure of a whole, Make electronic components to micro-miniaturization, Low-power, intelligent and high reliability of a major step. It is represented by the letter "IC" in the circuit.
is a new type of semiconductor device developed in the late the 1950s and 60. It is oxidized, lithography, diffusion, epitaxy, aluminum and other semiconductor manufacturing processes, the formation of a certain function of the circuit required by the semiconductor, resistance, capacitance and other components and their connecting wire are all integrated in a small piece of silicon, and then welding encapsulated in a shell of electronic devices. The package shell has a round shell type, flat type or double row direct inserting type and so on many forms. Integrated circuit technology including chip manufacturing technology and design technology, mainly embodied in processing equipment, processing technology, packaging testing, mass production and design innovation capabilities.
