A semiconductor is a material whose electrical conductivity falls between that of a conductor and that of an insulator, most commonly silicon.

Selective doping creates P-N junctions that form transistors, the fundamental switching elements of all digital and analog electronics. The fab process etches billions of transistors onto wafers to produce chip dies, and Moore's Law has driven that scaling exponentially for decades, from micron-scale features to process nodes below 3 nm.
