Integrated Circuit, abbreviated as IC; As the name suggests, it refers to a circuit that integrates a certain number of commonly used electronic components, such as resistors, capacitors, transistors, and the connections between these components, through semiconductor technology, with specific functions. It is a new type of semiconductor device that developed from the late 1950s to the 1960s. It is an electronic device that undergoes semiconductor manufacturing processes such as oxidation, photolithography, diffusion, epitaxy, and aluminum evaporation, integrating the semiconductor, resistor, capacitor, and other components required to form a circuit with certain functions, as well as the connecting wires between them, onto a small piece of silicon wafer, and then welded and packaged in a single shell. Its packaging shell comes in various forms such as round shell, flat, or dual inline. Integrated circuit technology includes chip manufacturing technology and design technology, mainly reflected in the ability of processing equipment, processing technology, packaging testing, batch production, and design innovation.
