DI(T-BUTYLAMINO)SILANE Chemical Properties,Usage,Production

Uses

Bis(t-butylamino)silane is a useful reagent, catalyst, and precursor. It is applicated in thin film deposition. Aminosilanes are the best choice as Si source for the deposition of hafnium silicates (HfSiO) and hafnium silicon oxynitrides (HfSiON).
