Integrated circuit: Circuit (mainly including semiconductor devices and passive components, etc.) in miniaturization, adoption of a certain process, the transistor, resistor in a circuit, capacitance and inductance and components and wiring interconnection together, make on a small piece of or a few small piece of semiconductor wafer or medium substrate, and then encapsulated in a tube and shell inside, become a micro structure of the circuit functions; All the components in the structure have formed a whole, so that electronic components toward miniaturization, low power consumption, intelligent and high reliability of a big step forward.

It is a miniature electronic device or component, denoted by the letter "IC" in the circuit, invented by Jack Kilby (Ge based integrated circuit) and Robert Noyth (Si based integrated circuit). Most of the current semiconductor industry applications are silicon-based integrated circuits, which are a new type of semiconductor devices developed in the late 1950s and 1960s.
