Semiconductor ICs are fabricated in a planar process which includes three key process steps – photolithography, deposition (such as chemical vapor deposition), and etching. Integrated circuits are composed of many overlapping layers, each defined by photolithography, and normally shown in different colors.

As of 2018, the most complex ICs may have over 15 layers of interconnect. Each level of interconnect is separated from each other by a layer of dielectric. To make vertical connects between interconnects on different levels, vias are used.
