nm = nanometer
PURITY AND FLATNESS REQUIREMENTS FOR WAFERS ARE EXTREME,
AS SCALING THEM INTO THE MACRO WORLD SHOWS
Particles
Particle size specified in the nm range. Requirements are
equivalent to a maximum of 10 grains of sand distributed
over the city of Munich.
Flatness
20 nm on a wafer are equivalent to the height of a leaf on
the surface of Lake Chiemsee – or a single bacteria on a
tennis court.
