Integrated circuit chip (IC chip) is a chip made by putting a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic base. IC chip includes wafer chip and package chip. The corresponding IC chip production line consists of wafer production line and package production line.
Integrated circuit is a kind of micro electronic device or component. It uses certain technology to interconnect the transistor, diode, resistance, capacitance, inductance and other components and wiring needed in a circuit and make them on one or several small semiconductor chips or dielectric substrates, and then package them in a shell to become a micro junction with the required circuit function All of the components have formed a whole structure, which makes the electronic components a big step forward in miniaturization, low power consumption and high reliability. It is indicated by the letter "IC" in the circuit.
