TRI-T-BUTOXYSILANOL Chemical Properties,Uses,Production
Uses
Silicon oxide source for rapid atomic layer deposition to prepare various nanolaminates.
Uses
Uses
Tris(tert-alkoxy)silanols reacts with tetrakis(dimethylamino)-hafnium vapor(Hf(N(CH3)2)4) for vapor phase deposition of hafnium silicate glass films. Tris(tert-butoxy)silanol is used for atomic layer deposition (ALD) of highly conformal layers of amorphous silicon dioxide and aluminum oxide nanolaminates.
General Description
Tris(tert-butoxy)silanol can react with various metal alkyl amides to act as precursors for vapor deposition metal silicates. It also acts as a suitable precursor for deposition of silica.
