Single Crystal Slice

Silicon is earth one of the most abundant materials store from the 19th century, scientists have found crystalline silicon semiconductor characteristics, it almost everything changed, and even human thinking. Until the 1960s began, silicone materials replaced the original germanium material. Silicone material - due to its high temperature resistant and resist radiation performance is good, especially suitable for making the characteristics of high power devices become application a kind of most semiconductor materials, the current integrated circuit with silicon semiconductor device most is the material manufacturing.

Single of silicon. Have basic complete dot matrix structure of the crystal. Different directions with different properties, is a good half guide material. Purity 99.9999%, even to the requirements 99.9999999% above. Used in the manufacture of semiconductor devices and solar battery, etc. With high-purity polysilicon on planarization into furnace control.

Molten elemental silicon in silicon atom during solidification in diamond crystal lattice are arranged in many forms, if these forms of the same grain grown faces orientation, the grain combine into parallel and crystalline silicon. Monocrystalline silicon has allowed the physical properties of metal, have weaker conductivity, conductivity increases with temperature, have significant half electrical conductivity. Ultra pure monocrystalline silicon is intrinsic semiconductors. In the super pure monocrystalline silicon adding trace amounts of Ⅲ A group element, such as boron may raise its conductive degree, and the formation of p type silicon semiconductor; If adding trace amounts of Ⅴ A group element, such as phosphorus or arsenic can also improve conductive degree, forming n-type silicon semiconductor. Monocrystalline is usually made first molykote amorphous silicon, then polysilicon or draw method or suspension area with fusion method in from grow to stick monocrystalline melt.
