SinoPhorus makes ultra-high-purity wet electronic chemicals for semiconductors, including electronic-grade phosphoric acid, sulfuric acid, and functional wet chemicals.
SinoPhorus runs a wet-electronic-chemicals business spanning general and functional chemistries alongside formula chemicals, specialty gases and chemical recycling. It develops, produces and sells ultra-high-purity electronic chemicals for semiconductors, with general wet lines of electronic-grade phosphoric acid and sulfuric acid and functional lines covering etching solutions, developers, cleaning agents, regenerators and stripping solutions. The business also spans high-purity chemicals.
SinoPhorus differentiates its electronic chemicals on purity grade, having developed and mass-produced electronic-grade phosphoric acid at the SEMI C36-1121 G3 grade and electronic-grade sulfuric acid at the SEMI G5 grade. Its electronic-grade phosphoric acid has been supplied in batches to mainstream 8-inch and 12-inch semiconductor fabs at home and abroad.
Phosphoric acid, an etching chemical sold for circuit-board and semiconductor manufacturing, strips copper conductor coatings and etches silicon nitride layers.
