Before the integrated circuit, electronic components, such as transistors, resistors, diodes, inductors, and capacitors, were manually wired together on a board. The integrated circuit allowed for more powerful, lightweight, miniaturized applications by integrating components onto one chip of material. The digital integrated circuit consists of transistors, contacts, and interconnects. To be sure, though, there is an inflection point taking place in leading-edge chips. The transistor resides on the bottom of the structure and serves as a switch. The interconnects, which reside on the top of the transistor, consist of tiny copper wiring schemes that transfer electrical signals from one transistor to another. The transistor structure and interconnects are connected by a layer called the middle-of-line (MOL). The MOL layer consists of a series of tiny contact structures.
