The Structure Of Monocrystalline Silicon Wafer
- Mar 12, 2018 -

Molten elemental silicon in the solidification of the silicon atom in the diamond lattice arranged into three-dimensional space in the long order of the form of monocrystalline silicon. Monocrystalline Silicon has the properties of quasi metal, has a weak conductivity, and its conductivity increases with the increase of temperature, there is a significant semi conductive.

Ultra-Pure monocrystalline silicon is the intrinsic semiconductor. The addition of trace Ⅲa group elements, such as boron, to the ultra pure monocrystalline silicon can increase the conductivity and form P-type silicon semiconductors, such as the addition of trace amounts of ⅴa elements, such as phosphorus or arsenic, can increase the conductivity and form N-type silicon semiconductors. Mono-crystalline silicon is usually made of polycrystalline or amorphous silicon, and then a rod-like monocrystalline silicon is grown from the melt by direct-pulling or suspension-zone fusion. Monocrystalline silicon is mainly used to make semiconductor components. Silica crystalline silicon is dark blue, very brittle, and is typical of semiconductors. The chemical property is very stable. At room temperature, it is difficult to react with other substances except for hydrogen fluoride.
