Single atom transistors
Now that is small!

The atom was etched into a silicon bed with "gates" to control electrical flow and metallic contacts to apply voltage, researchers reported in the journal Nature Nanotechnology. It is the first such device to be precisely positioned using a repeatable technology, they said, and may one day help ease the way toward creation of a so-called quantum computer that would be significantly smaller and faster than existing technology.
