Silicon
Silicon is the raw material most often used in integrated circuit (IC)
fabrication. It is the second most abundant substance on the earth. It is
extracted from rocks and common beach sand and put through an exhaustive
purification process. In this form, silicon is the purist industrial substance
that man produces, with impurities comprising less than one part in a billion.
That is the equivalent of one tennis ball in a string of golf balls stretching
from the earth to the moon.
Semiconductors are usually materials which have energy-band gaps smaller
than 2eV. An important property of semiconductors is the ability to change
their resistivity over several orders of magnitude by doping. Semiconductors
have electrical resistivities between 10-5 and 107 ohms. Semiconductors can be
crystalline or amorphous. Elemental semiconductors are simple-element
semiconductor materials such as silicon or germanium.
Silicon is the most common semiconductor material used......
