Constructed with world-leading technologies and state-of-the-art facilities, our production yields products that surpass the world’s premium G5 grade standards, securing a leading position in the industry. Widely adopted in the manufacturing of memory, logic and automotive power semiconductor chips, our products have realized domestic substitution of imported equivalents, putting an end to the long-standing foreign monopoly on high-quality electronic chemicals.

 

Electronic-grade hydrofluoric acid is one of the critical fundamental chemical materials for the microelectronics industry and falls under the category of wet electronic chemicals. Given that the purity and cleanliness of electronic-grade hydrofluoric acid exert a vital impact on the yield, performance and reliability of integrated circuits, its production imposes extremely stringent technical requirements. At present, domestic market demand is largely met by imported supplies.

 

In the wet electronic chemical sector, the SEMI International Standards are globally recognized grading benchmarks, consisting of five tiers, among which Grade 5 (G5) represents the highest specification. Domestic manufacturers of electronic-grade hydrofluoric acid generally produce low-grade products. Only around three enterprises, including our company, are capable of manufacturing products meeting Grade 4 (G4) or above for semiconductor applications; the other two are Duofuoduo and Zhongjuxin (formerly Juhua Co., Ltd.). The localization rate of high-end electronic-grade hydrofluoric acid remains low across the country.
