    摘要: In one embodiment, a method for depositing a tungsten material on a substrate within a process chamber is provided which includes exposing the substrate to a gaseous mixture containing a tungsten precursor and a reducing gas to deposit a tungsten nucleation layer on the substrate during a tungsten deposition process. The process further includes removing reaction by-products generated during the tungsten deposition process from the process chamber, exposing the substrate to the reducing gas to react with residual tungsten precursor within the process chamber during a soak process, removing reaction by-products generated during the soak process from the process chamber, and repeating the tungsten deposition process and the soak process during a cyclic deposition process. In the examples, the reducing gas may contain diborane or silane.

    摘要: A method of forming a tungsten nucleation layer using a sequential deposition process. The tungsten nucleation layer is formed by reacting pulses of a tungsten-containing precursor and a reducing gas in a process chamber to deposit tungsten on the substrate. Thereafter, reaction by-products generated from the tungsten deposition are removed from the process chamber. After the reaction by-products are removed from the process chamber, a flow of the reducing gas is provided to the process chamber to react with residual tungsten-containing precursor remaining therein. Such a deposition process forms tungsten nucleation layers having good step coverage. The sequential deposition process of reacting pulses of the tungsten-containing precursor and the reducing gas, removing reaction by-products, and than providing a flow of the reducing gas to the process chamber may be repeated until a desired thickness for the tungsten nucleation layer is formed.

    摘要: In one embodiment, a method for forming a tungsten-containing material on a substrate is provided which includes forming a tungsten nucleation layer by sequentially exposing a substrate to a boron-containing gas and a tungsten-containing gas within a processing chamber during an atomic layer deposition process, and forming a tungsten bulk layer on the tungsten nucleation layer by exposing the substrate to a processing gas that contains the tungsten-containing gas and a reactive precursor gas within another processing chamber during a chemical vapor deposition process. In one example, the tungsten nucleation layer is deposited on a dielectric material, such as silicon oxide. In another example, the tungsten nucleation layer is deposited on a barrier material, such as titanium or titanium nitride. Other examples provide that the tungsten nucleation layer and the tungsten bulk layer are deposited in the same processing chamber.
