Ultra Pure Silicon

Weden Metal Co.,Limited | Updated: Apr 21, 2017

Ultra-pure silicon (no more than a few atoms per 1000 of impurities) is the most important semiconductor materials, widely used in computers, microwave communications, optical fiber communication, solar power generation and so on. Semiconductor silicon material development quickly, the dosage of monocrystalline silicon per year exceeds 2500 tons, silicon wafer consumption of 2.5 billion square inches. The research and production of silicon materials in China also has a great development, with a diameter of 3 inches below the single crystal has reached the international level, and the establishment of cutting, grinding, throwing technology and equipment, but the overall level and international still have a certain gap. Therefore, our country ultra pure silicon development potential is very big, heavy responsibilities.

Why is the present age known as the silicon Age? At the Seventh International Conference on crystalline silicon production, scientists called the present age of silicon. Why does silicon mention such a high position? This is because the world is now in the era of information from the industry. In the industrial age, the lead is steel, so the volume of steel production marks a country's economic and military strength. In the information age, the lead is semiconductor material-silicon. There are many varieties available for semiconductor materials, but there are not many varieties of industrial production, mainly silicon, germanium, gallium arsenide and gallium phosphide, and silicon accounted for about 90% percent of the entire semiconductor material production. This is why people call the present age of silicon.
