INSIGHT

Why Semiconductors Matter

  • Semiconductors conduct electricity moderately, and that 'being mid' is what makes them uniquely useful in electronics.
  • That borderline conductivity lets tiny transistor 'switches' flip between on and off with minimal energy.

Transistors As Tiny Electronic Switches

  • A transistor is simply a device that controls electrical flow and, in computers, acts as a tiny controllable switch.
  • Using semiconductors means switches can toggle electronically at the speed of electrons without moving parts.

Making A Whole Circuit From One Chip

  • An integrated circuit etches all parts of a circuit into one piece of semiconductor instead of assembling discrete components.
  • That single-crystal approach drastically shrinks size, cost, and assembly complexity.
