Factoid #16
Silicon metal used in the semiconductor industry
is purified to 99.9999999%. This impurity level is equivalent to 100 parts
per billion (1x10-7).
Using this ultra pure material, single
silicon crystals up to 18 inches in diameter are grown. Slices of this
starting material form the substrate on which CPU cores are fabricated.
