Abstract
Methods for depositing silicon-containing thin films, such as SiCN films, on a substrate in a reaction space are provided. The methods can include a vapor deposition process utilizing a vapor-phase silicon precursor comprising a halogen and a second vapor-phase reactant comprising an amine reactant. In some embodiments an atomic layer deposition (ALD) cycle comprises alternately and sequentially contacting the substrate with a silicon precursor comprising a halogen and a second reactant comprising an amine reactant. In some embodiments a SiCN thin film is deposited by alternately contacting the substrate with a halosilane such as octachlorotrisilane and an amine reactant comprising a diamine or triamine.
