A semiconductor is a substance with conductive properties which can be altered with electricity; it can be both a conductor and an insulator. Silicon performs as a semiconductor when chemically combined with other elements.

Complex electronic circuits can be built into the surface of a thin layer of silicon-based semiconductor. The continuing development of semiconductor technology is a foundation for the electronics and high-tech industry sectors.
