Description
General introduction:Wafer refers to the silicon wafer used in the manufacture of silicon semiconductor integrated circuits. Because of its circular shape, it is called a wafer; it can be processed into various circuit component structures on the silicon wafer, and become an IC with specific electrical functions. product. The original material of the wafer is silicon, and the surface of the earth's crust has an inexhaustible amount of silicon dioxide. Silica ore is refined by electric arc furnace, chlorinated with hydrochloric acid, and distilled to produce high-purity polysilicon with a purity of 99.999999999%.
Product Description:The starting material of the wafer is silicon. Silica ore is refined by electric arc furnace, chlorinated with hydrochloric acid, and distilled to produce high-purity polysilicon with a purity of 99.999999999%. The polycrystalline silicon is melted, seed crystals are planted in the molten liquid, and then slowly pulled out to form a cylindrical monocrystalline silicon ingot. Since the silicon ingot is a seed crystal whose crystal plane orientation is determined It is gradually formed in the molten silicon raw material, and this process is called "crystal growth". The silicon ingot is then cut into sections, rolled, sliced, chamfered, polished, laser engraved, and packaged to become silicon wafers, which are "wafers".
