The aqueous solution of hydrogen fluoride gas is a clear, colorless, fuming corrosive liquid with a strong pungent odor, easily soluble in water and ethanol, and slightly soluble in ether. Hydrofluoric acid is a weak acid with strong corrosiveness, which can strongly corrode metal, glass and silicon-containing objects.
It is generally produced in laboratories with fluorite (mainly composed of calcium fluoride) and concentrated sulfuric acid. It needs sealed in a plastic bottle
The products are mainly used in the manufacture of integrated circuits (IC) and very large scale integrated circuits (VLSI)
Electronic grade high-purity hydrofluoric acid is one of the key auxiliary materials. It is mainly used for wafer surface cleaning, cleaning and etching during chip processing. In the solar photovoltaic industry, it is used in the fields of silicon wafer surface cleaning and etchant.
The first process from silicon ingot to silicon wafer, and then to the cell: the product will be used in the cleaning and texturing process.
In the liquid crystal display industry, it is used for glass substrate cleaning, silicon nitride, silicon dioxide etchant. It is also widely used in TFT-LCD and semiconductor industries.
It can also be used as analytical reagent, atomic energy industrial chemical reagent and preparation of high-purity fluorine-containing chemicals.
At present, it is basically used as an etchant and cleaning agent in the microelectronics industry in China, and the amount used in other aspects is small
Electronic grade hydrofluoric acid is one of the key basic chemical materials in the manufacture of microelectronics industry. It can be used in combination with nitric acid, glacial acetic acid, hydrogen peroxide and ammonium hydroxide. It is widely used in large-scale integrated circuits, thin-film liquid crystal displays, semiconductors, etc. In the electronics industry, etc., it is mainly used for chip cleaning and corrosion, and can also be used as an analytical reagent and for the preparation of high-purity fluorine-containing chemicals. Its purity and cleanliness have a very important impact on the yield, electrical performance and reliability of integrated circuits.
