IC is the major of integrated circuit design.
Integrated circuit design is a discipline of electronic engineering and computer engineering, its main content is the use of professional logic and circuit design technology to design integrated circuits (ics). IC design involves both hardware and software expertise. Integrated circuit design involves the creation of models for electronic devices (such as transistors, resistors, capacitors, etc.) and interconnects between devices. All the devices and interconnects need to be placed on a semiconductor substrate material, and these components are placed on a single silicon substrate through a semiconductor device manufacturing process (such as lithography, etc.) to form the circuit.
