0.18 micron technology

From www.whatis.com (see the second to the last line for .18 micron):

micron

A micron (short for micrometer) is one-millionth of a meter. It can also be expressed as:
10-6 meter
One thousandth of a millimeter
One 25-thousandth of an inch
The micron is a unit of measure for the core in a optical fiber cable, for which the most common diameter is 62.5 microns. It is also used to measure the line width on a microchip. Today's microprocessors and memory chips are typically built using 0.35 and 0.25 line widths.

Recently, a 0.18 micron line width has been achieved and is being used in the latest processors from Intel and AMD.

A human hair is said to be about 50 microns wide.
