nanometre
含义: A metric unit of length equal to one billionth of a metre, used to measure atomic and molecular structures, light wavelengths, and features in advanced semiconductor technology.
The nanometre (nm) is the defining scale of nanotechnology. Visible light wavelengths range from about 380 to 700 nanometres. In the semiconductor industry, process nodes are described in nanometres — the smaller the number, the more advanced the chip. The prefix 'nano-' has entered popular vocabulary to convey extreme smallness, as in 'nanotechnology' and 'nanoscale.'
