The chip is an important cornerstone of manufacturing power. Electronic chemicals are the core materials of chip manufacturing, wafer, lithography, etching and the whole industry chain is inseparable from high-purity electronic chemicals. In this paper, an efficient separation component, BH filler, has a unique broken line structure, and its separation performance is significantly better than that of traditional fillers. The successful industrial application has produced a variety of electronic grade chemicals represented by electronic grade dichlorodihydrosilane, and the future development prospect is discussed.
