Abstract: As the semiconductor chip and LCD manufacturing industries have transfered to China,China will gradually become a world′s large LCD industrial base.Demand for electronic-grade phosphoric acid in China is growing, and the expansion of electronic-grade phosphoric acid production has become the inevitable trend of the development of fine phosphate chemical industry at present.Electronic-grade phosphoric acid is widely used in large scale integrated circuit (IC),thin film liquid crystal display (TFT-LCD),semiconductor,and other microelectronics industries.Usually it is used as cleaning and etching agents.Application fields,quality standard,purification technology,and present R&D status of electronic-grade phosphoric acid at home and abroad were introduced in detail.

Key words: phosphoric acid, electronic-grade phosphoric acid, purification technology, present development status
