Abstract:
1. A method of selectively depositing a thin film on a first surface of a substrate in a reactor relative to a second surface, the method comprising conducting a plurality of deposition cycles comprising: supplying a noble metal precursor to the reactor; supplying a purge gas to the reactor after supplying the noble metal precursor; and supplying ammonia gas to the reactor after supplying the purge gas; wherein the ammonia gas does not comprise ammonia plasma; and wherein the first surface comprises a high-k material, a metal, a metal nitride, a metal oxide, a metal carbide, a metal boride, another conductive metal compound or mixtures thereof; the second surface comprises a material selected from the group consisting of silicon oxides, silicon nitrides, silicon oxynitrides, fluorinated silica glass (FSG), carbon doped silicon oxide (SiOC) and materials containing more than about 50% silicon oxide; and the thin film is selectively deposited on the first surface relative to the second surface.
