Abstract: Methods and apparatus for increasing reflectivity of an aluminum layer on a substrate. In some embodiments, a method of depositing an aluminum layer on a substrate comprises depositing a layer of cobalt or cobalt alloy or a layer of titanium or titanium alloy on the substrate with a chemical vapor deposition (CVD) process, pre-treating the layer of cobalt or cobalt alloy with a thermal hydrogen anneal at a temperature of approximately 400 degrees Celsius if a top surface of the layer of cobalt or cobalt alloy is compromised, and depositing a layer of aluminum on the layer of cobalt or cobalt alloy or the layer of titanium or titanium alloy with a CVD process at a temperature of approximately 120 degrees Celsius. Pre-treatment of the layer of cobalt or cobalt alloy may be accomplished for a duration of approximately 60 seconds to approximately 120 seconds.

Abstract: Methods of depositing a metal film are discussed. A metal film is formed on the bottom of feature having a metal bottom and dielectric sidewalls. Formation of the metal film comprises exposure to a metal precursor and an alkyl halide catalyst while the substrate is maintained at a deposition temperature. The metal precursor has a decomposition temperature above the deposition temperature. The alkyl halide comprises carbon and halogen, and the halogen comprises bromine or iodine.

Abstract: Methods and apparatus for removing deposits in self-assembled monolayer (SAM) based selective deposition process schemes using cryogenic gas streams are described. Some methods include removing deposits in self-assembled monolayer (SAM) based selective depositions by exposing the substrate to cryogenic aerosols to remove undesired deposition on SAM protected surfaces. Processing chambers for cryogenic gas assisted selective deposition are also described.

Abstract: The use of a cyclic 1,4-diene reducing agent with a metal precursor and a reactant to form metal-containing films are described. Methods of forming the metal-containing film comprises exposing a substrate surface to a metal precursor, a reducing agent and a reactant either simultaneously, partially simultaneously or separately and sequentially to form the metal-containing film.

Abstract: Methods for selectively depositing on non-metallic surfaces are disclosed. Some embodiments of the disclosure utilize a blocking compound to form a blocking layer on metallic surfaces. Deposition is performed to selectively deposit on the unblocked non-metallic surfaces. Some embodiments of the disclosure relate to methods of forming metallic vias with decreased resistance. Some embodiments utilize an unsaturated hydrocarbon as a blocking compound. Some embodiments utilize a triazole as a blocking compound.

Abstract: Methods of depositing a film selectively onto a first material relative to a second material are described. The substrate is pre-cleaned by heating the substrate to a first temperature, cleaning contaminants from the substrate and activating the first surface to promote formation of a self-assembled monolayer (SAM) on the first material. A SAM is formed on the first material by repeated cycles of SAM molecule exposure, heating and reactivation of the first material. A final exposure to the SAM molecules is performed prior to selectively depositing a film on the second material. Apparatus to perform the selective deposition are also described.

Abstract: Methods of depositing a film selectively onto a first substrate surface relative to a second substrate surface are described. The methods include exposing the substrate surfaces to a blocking compound to selectively form a blocking layer on at least a portion of the first surface over the second surface. The substrate is sequentially exposed to a metal precursor with a kinetic diameter in excess of 21 angstroms and a reactant to selectively form a metal-containing layer on the second surface over the blocking layer or the first surface. The relatively larger metal precursors of some embodiments allow for the use of blocking layers with gaps or voids without the loss of selectivity.

Abstract: A method for forming conductive structures for a semiconductor device includes depositing a reflow material in features, e.g. vias, formed in a dielectric layer. A high melting point material is deposited in the feature and is reflowed and annealed in an ambient comprising one or more of hydrogen molecules, hydrogen ions, and hydrogen radicals at a temperature greater than 300° C. to fill the feature with a reflow material.
