					SemiConductor - What is SemiConductor?
Semiconductors are widely used in electronics to make components such as diodes,
transistors, thyristors, integrated circuits as well as semiconductor lasers.

A semiconductor is usually a solid chemical element or compound that can conduct
electricity under some conditions, making it a good medium for the control of electrical
current. Its conductance varies depending on the current or voltage applied to a control
electrode. Semiconductor is use for manufacturing chips.

A semiconductor device can perform the function of a vacuum tube having hundreds of
times its volume. A single integrated circuit (IC), such as a microprocessor chip, can do
the work of a set of vacuum tubes that would fill a large building and require its own
electric generating plant.
