ic is a micro electronic device; IC chips are integrated circuits formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) placed on a plastic base to make a chip.
IC chip includes wafer chip and package chip, and the corresponding IC chip production line is composed of wafer production line and package production line.
Integrated circuit is a miniature electronic device or component, using a certain process, the required transistors, diodes, resistors, capacitors and inductors in a circuit and wiring interconnect together, made in a small or several small pieces of semiconductor chip or dielectric substrate, and then packaged in a tube shell, become a miniature structure with the required circuit function; All components have been structurally formed as a whole, making electronic components a big step forward in terms of miniaturization, low power consumption and high reliability. It is represented in the circuit by the letter \"IC\".
