    摘要: In one embodiment, a method for forming a barrier material on a substrate is provided which includes exposing a dielectric layer on the substrate to a plasma during a preclean process, wherein the dielectric layer contains a feature having sidewalls and a bottom surface, and depositing a tungsten-containing barrier material containing tungsten nitride on the sidewalls and the bottom surface of the feature during a cyclic layer deposition process. The method further provides depositing a metal-containing seed layer on the tungsten-containing barrier material and depositing a metal-containing layer over the metal-containing seed layer to fill the feature. In another embodiment, the method provides conducting the cyclic layer deposition process within a process chamber having an expanding channel centralized above a substrate support and having a bottom surface sized and shaped to substantially cover the substrate, and sequentially exposing the substrate to precursor gases flowing from the expanding channel during the cyclic layer deposition process.

    摘要: A method of noble metal layer formation for high aspect ratio interconnect features is described. The noble metal layer is formed using a cyclical deposition process. The cyclical deposition process comprises alternately adsorbing a noble metal-containing precursor and a reducing gas on a substrate structure. The adsorbed noble metal-containing precursor reacts with the adsorbed reducing gas to form the noble metal layer on the substrate. Suitable noble metals may include, for example, palladium (Pd), platinum (Pt) cobalt (Co), nickel (Ni) and rhodium (Rh).

    摘要: A method for depositing a cap layer over a metal-containing interconnect is provided. In one aspect, the cap layer is formed by introducing a pulse of a metal-containing compound followed by a pulse of a nitrogen-containing compound. In one aspect, the cap layer comprises tantalum nitride. The cap layer provides good barrier and adhesive properties, thereby enhancing the electrical performance and reliability of the interconnect.

    摘要: Methods for depositing a metal silicon nitride layer on a substrate during an atomic layer deposition (ALD) process. The methods provide positioning a substrate within a process chamber containing a centralized expanding channel that conically tapers towards and substantially covers the substrate, flowing a process gas into the centralized expanding channel to form a circular flow pattern, exposing the substrate to the process gas having the circular flow pattern, and exposing the substrate sequentially to chemical precursors during an ALD process to form a metal silicon nitride material. In one example, the ALD process provides sequentially pulsing a metal precursor, a nitrogen precursor, and a silicon precursor into the process gas having the circular flow pattern. The metal silicon nitride material may contain tantalum or titanium. In other examples, the process gas or the substrate may be exposed to a plasma.

    摘要: Embodiments of the invention provide a method for forming tantalum nitride materials on a substrate by employing an atomic layer deposition (ALD) process. The method includes heating a tantalum precursor within an ampoule to a predetermined temperature to form a tantalum precursor gas and sequentially exposing a substrate to the tantalum precursor gas and a nitrogen precursor to form a tantalum nitride material. Thereafter, a nucleation layer and a bulk layer may be deposited on the substrate. In one example, a radical nitrogen compound may be formed from the nitrogen precursor during a plasma-enhanced ALD process. A nitrogen precursor may include nitrogen or ammonia. In another example, a metal-organic tantalum precursor may be used during the deposition process.
