If you have used anything that is computerized or uses radio waves, you have utilized a semiconductor. While semiconductors can be made of a variety of different materials, the most common one used is silicon. Let’s take a look at some things you should know about semiconductors and how they relate to silicon prices.
A semiconductor is a solid material whose electrical conductivity falls between insulators and conductors. The conductivity of a semiconductor can then be controlled by adding impurities, which are a specific amount of other materials, to the semiconductor.
While silicon is the common material used to make a semiconductor, other materials are used. Some of these include germanium, gallium arsenide, germanium, indium phosphide, sapphire, and quartz.
An N-type semiconductor carries current mainly in the form of negatively-charged electrons. Meanwhile, a P-type semiconductor carries current mostly as electron deficiencies called holes, which has a positive electric charge that is equal and opposite to the charge on an electron.
Semiconductor wafers are available in a wide variety of diameters. The first semiconductor wafer, manufactured in the United States in 1960, had a diameter that was a mere 1-inch. Today, however, the standard semiconductor wafer is around 12-inches.
