Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Application

Tris(dimethylamino)silane (TDMAS) is used as an organosilicon source for the deposition of Si oxynitride; carbonitride; nitride and oxide thin films. It is also used to form multicomponent silicon containing thin films. 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.

Packaging

25 g in stainless steel cylinder
