| This is an 800x magnification of a few bits of RAM from an early Motorola microcontroller. Although the actual size of what you see in this picture would fit on a pinhead, the elements in the devices on this chip are several microns wide, which is quite large by today's standards. |
micron
a unit of length equal to 10--6 metre. It is being replaced by the micrometre, the equivalent SI unit

(mechanics)
A unit of pressure equal to the pressure exerted by a column of mercury 1 micrometer high, having a density of 13.5951 grams per cubic centimeter, under the standard acceleration of gravity; equal to 0.133322387415 pascal; it differs from the millitorr by less than one part in seven million. Also known as micrometer of mercury.
