    Abstract: Embodiments of the present invention relate to an apparatus and method of cyclical deposition utilizing three or more precursors in which delivery of at least two of the precursors to a substrate structure at least partially overlap. One embodiment of depositing a ternary material layer over a substrate structure comprises providing at least one cycle of gases to deposit a ternary material layer. One cycle comprises introducing a pulse of a first precursor, introducing a pulse of a second precursor, and introducing a pulse of a third precursor in which the pulse of the second precursor and the pulse of the third precursor at least partially overlap. In one aspect, the ternary material layer includes, but is not limited to, tungsten boron silicon (WBxSiy), titanium silicon nitride (TiSixNy), tantalum silicon nitride (TaSixNy), silicon oxynitride (SiOxNy), and hafnium silicon oxide (HfSixOy). In one aspect, the composition of the ternary material layer may be tuned by changing the flow ratio of the second precursor to the third precursor between cycles.

    Abstract: Methods of depositing titanium nitride (TiN) films on a substrate are disclosed. The titanium nitride (TiN) films may be formed using a cyclical deposition process by alternately adsorbing a titanium-containing precursor and a NH3 gas on the substrate. The titanium-containing precursor and the NH3 gas react to form the titanium nitride (TiN) layer on the substrate. The titanium nitride (TiN) films are compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, an interconnect structure is fabricated. The titanium nitride films may also be used as an electrode of a three-dimensional capacitor structure such as for example, trench capacitors and crown capacitors.

    Abstract: A method of forming a composite tungsten film on a substrate is described. The composite tungsten film comprises sequentially deposited tungsten nucleation layers and tungsten bulk layers. Each of the tungsten nucleation layers and the tungsten bulk layers have a thickness less than about 300 null. The tungsten nucleation layers and the tungsten bulk layers are formed one over the other until a desired thickness for the composite tungsten film is achieved. The resulting composite tungsten film exhibits good film morphology. The tungsten nucleation layers may be formed using a cyclical deposition process by alternately adsorbing a tungsten-containing precursor and a reducing gas on the substrate. The tungsten bulk layers may be formed using a chemical vapor deposition (CVD) process by thermally decomposing a tungsten-containing precursor.
