Silicon Wafer | Silicon Wafer Manufacturing Process - …
Silicon is a chemical element that makes up almost 30% of the earth’s crust. Next to oxygen, it is the most abundant element in nature. Silicon is the most common material to build semiconductors and microchips with despite the fact that on its own, it doesn’t conduct electricity very well.
Ionic and Metallic Bonding
The ''free valence electrons'' model explains several properties of metals: they conduct electricity, are malleable and ductile (can have their shape changed without breaking) and are not volatile. As mentioned above, they type of bonding observed in the solid state determine the properties of solids.

Does carbon conduct electricity? If it does, why is it …
Hi Denise. Everything conducts electricity, just some things conduct it better (faster) than others. Carbon is a really good conductor (or, at least, its graphitic form is). Conductivity depends on how the electrons behave, not on the specific mat
4 major uses for silicon in technology - Electronic Products
18/11/2016· For transistors, the material is doped by adding a small impurity which enables the electrons to move around, conduct electricity, and create reliable semiconductors for voltage. When heated into a molten state, silicon can be formed into semi-conductive wafers to serve as the base for integrated circuits, or microchips.
Doping (semiconductor) - Wikipedia
History The effects of semiconductor doping were long known empirically in such devices as crystal radio detectors and selenium rectifiers.For instance, in 1885 Shelford Bidwell, and in 1930 the German scientist Bernhard Gudden, each independently reported that the properties of semiconductors were due to the impurities contained within them.
