Descripción

General description

Tris(dimethylamino)silane is an organosilicon compound with high volatility and thermal stability, widely used as a vapor deposition precursor to fabricate silicon-containing thin films for various applications, including solar cells, fuel cell catalysts, and semiconductors. The depositions can be carried out at low substrate temperatures (<150). The melting point and vapor pressure of TDMAS is in a suitable working range, thus making it a very good vapor deposition precursor.

Application

Tris(dimethylamino)silane can be used:

• As a silicon source for deposition of aluminum silicate on TiO₂ anodes for dye-sensitized solar cells vis atomic layer deposition method.
• As a precursor to fabricate functionalized Si reinforced separators for Li-ion batteries.
