What unit is used to measure the width of the smallest wire on a computer chip?

EXPLANATION

The smallest wire on a chip is measured in microns. Current chips have wires that are less than one micron wide, while a human hair is about 100 microns thick.  

 The smallest physical units in my computer are the electron holes in the P-N junctions of the semiconductors: they are so small that they are not even there: it's just an imbalance in the electromagnetic force. If that's not quite the answer you're looking for, then you can go with the diode on the VLSI chip that contains that P-N junction.
