How small can transistors get?
The amazing shrinking transistor! Watch it contract a million times until it becomes a tiny dot visible only under a powerful microscope!
That’s Engineering!
- transistor – the main component in all modern electronics, has diminished in size since being invented in 1947.
- semiconductor – a cross between a good conductor (such as copper) and a good insulator (such as rubber). It can be made to accept or reject the flow of electrons in a circuit.
