According to the report of the Science and Technology Daily, the domestic production of electronic polysilicon production, the purity requirements of 99.999999999%.
As a key basic material for integrated circuits, in the past, the polysilicon materials used in integrated circuits in the Chinese market were basically completely dependent on imports. However, with domestic purity of 99.999999999% required for mass production of domestic electronic grade polysilicon, we will break this situation.
Compared to 99.9999% purity of solar grade polysilicon, the purity requirement of electronic grade polysilicon reaches 99.999999999%. The total impurity content of 5000 tons of electronic grade polysilicon is equivalent to the weight of a 1 dollar coin.
At present, the electronic grade polysilicon has been verified by customers and formed large-scale sales, breaking the monopoly of foreign high-purity materials for a long time, and filling the gap in the domestic technology of the industry.
