The Used Semiconductor Equipment
If you are searching the Used Semiconductor Equipment, this article will give you the information. A semiconductor is a substance that behaves as a conductor or insulator, depending on the temperature of the environment in which they are located. The semiconductor is chemical elements periodic table shown in the accompanying table. The most commonly used semiconductor element is silicon, but have identical behavior combinations of elements of groups II and III with those of groups VI and V respectively. Subsequently it has also begun using sulfur. The common feature of all is that they are tetravalent, with a silicon electron configuration s ² p ².
Intrinsic Semiconductors; It is a crystal of silicon that forms a structure tetrahedral similar to carbon by covalent bonds between atoms in the figure represented on the plane for simplicity. If an intrinsic semiconductor, as above, adds a small percentage of impurities, i.e. trivalent elements, the semiconductor is called extrinsic, and is said to be doped. Obviously, the impurities must be part of the crystal structure for replacing silicon atom.
