Embodiments of the invention provide methods for depositing dielectric materials on substrates during vapor deposition processes, such as atomic layer deposition (ALD). In one example, a method includes sequentially exposing a substrate to a hafnium precursor and an oxidizing gas to deposit a hafnium oxide material thereon. In another example, a hafnium silicate material is deposited by sequentially exposing a substrate to the oxidizing gas and a process gas containing a hafnium precursor and a silicon precursor. The oxidizing gas usually contains water vapor formed by flowing a hydrogen source gas and an oxygen source gas through a water vapor generator. In another example, a method includes sequentially exposing a substrate to the oxidizing gas and at least one precursor to deposit hafnium oxide, zirconium oxide, lanthanum oxide, tantalum oxide, titanium oxide, aluminum oxide, silicon oxide, aluminates thereof, silicates thereof, derivatives thereof or combinations thereof.

The invention provides a laminated dielectric layer for semiconductor devices formed by a combination of ZrO2 and a lanthanide oxide on a semiconductor substrate and methods of making the same. In certain methods, the ZrO2 is deposited by multiple cycles of reaction sequence atomic layer deposition (RS-ALD) that includes depositing a ZrI4 precursor onto the surface of the substrate in a first pulse followed by exposure to H2O / H2O2 in a second pulse, thereby forming a thin ZrO2 layer on the surface. After depositing the ZrO2 layer, the lanthanide oxide layer is deposited by electron beam evaporation. The composite laminate zirconium oxide / lanthanide oxide dielectric layer has a relatively high dielectric constant and can be formed in layers of nanometer dimensions. It is useful for a variety of semiconductor applications, particularly for DRAM gate dielectric layers and DRAM capacitors.
