    摘要: Refractory metal nitride layers for integrated circuit fabrication are described. The refractory metal nitride layer may be formed by sequentially chemisorbing alternating monolayers of a nitrogen-containing compound and a refractory metal compound onto a substrate. A composite refractory metal nitride layer is also described. The composite refractory metal nitride layer may be formed by sequentially chemisorbing monolayers of a nitrogen-containing compound and two or more refractory metal compounds onto a substrate.

    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: 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.
