摘要: The invention relates generally to processes for enhancing the deposition of noble metal thin films on a substrate by atomic layer deposition. Treatment with gaseous halides or metalorganic compounds reduces the incubation time for deposition of noble metals on particular surfaces. The methods may be utilized to facilitate selective deposition. For example, selective deposition of noble metals on high-k materials relative to insulators can be enhanced by pretreatment with halide reactants. In addition, halide treatment can be used to avoid deposition on the quartz walls of the reaction chamber.

摘要: Germanium has higher mobility than silicon and therefore is considered to be a good alternative semiconductor for CMOS technology. Surface treatments a can facilitate atomic layer deposition (ALD) of thin films, such as high-k dielectric layers, on germanium substrates. Surface treatment can comprise the formation of a thin layer of GeOx or GeOxNy. After surface treatment and prior to deposition of the desired thin film, a passivation layer may be deposited on the substrate. The passivation layer may be, for example, a metal oxide layer deposited by ALD.
