Abstract: Methods of depositing platinum group metal films of high purity, low resistivity, and good conformality are described. A platinum group metal film is formed in the absence of an oxidant. The platinum group metal film is selectively deposited on a conductive substrate at a temperature less than 200° C. by using an organic platinum group metal precursor.

Abstract: Described herein is a method for selectively cleaning and/or etching a sample. The method includes selectively forming a film in a trench of a substrate such that the trench may be selectively etched. A polymer film is deposited on the bottom surface of the trench without being deposited on the side wall. A second film is selectively formed in the trench without forming the second film on the polymer film. The polymer is then removed from the bottom surface of the trench and then etching is performed on the bottom surface of the trench using an etch chemistry, wherein the second film protects the side wall from being etched.

Abstract: Embodiments of the disclosure relate to methods for selectively removing metal material from the top surface and sidewalls of a feature. The metal material which is covered by a flowable polymer material remains unaffected. In some embodiments, the metal material is formed by physical vapor deposition resulting in a relatively thin sidewall thickness. Any metal material remaining on the sidewall after removal of the metal material from the top surface may be etched by an additional etch process. The resulting metal layer at the bottom of the feature facilitates selective metal gapfill of the feature.

Abstract: Methods for selectively depositing on metallic surfaces are disclosed. Some embodiments of the disclosure utilize a hydrocarbon having at least two functional groups selected from alkene, alkyne, ketone, hydroxyl, aldehyde, or combinations thereof to form a self-assembled monolayer (SAM) on metallic surfaces.

Abstract: Methods of depositing high purity metal films are discussed. Some embodiments utilize a method comprising exposing a substrate surface to an organometallic precursor comprising a metal selected from the group consisting of molybdenum (Mo), tungsten (W), osmium (Os), rhenium (Re), iridium (Ir), nickel (Ni) and ruthenium (Ru) and an iodine-containing reactant comprising a species having a formula RIx, where R is one or more of a C0-C10 alkyl, cycloalkyl, alkenyl, or alkynyl group and x is in a range of 1 to 4 to form a carbon-less iodine-containing metal film; and exposing the carbon-less iodine-containing metal film to a reductant to form a metal film. Some embodiments deposit a metal film with greater than or equal to 90% metal species on an atomic basis.

Abstract: Methods of depositing a film selectively onto a first substrate surface relative to a second substrate surface are described. The methods include exposing a substrate to a blocking molecule to selectively deposit a blocking layer on the first surface. The blocking layer is exposed to a polymer initiator to form a networked blocking layer. A layer is selectively formed on the second surface. The blocking layer inhibits deposition on the first surface. The networked layer may then optionally be removed.

Abstract: Methods for depositing metal oxide layers on metal surfaces are described. The methods include exposing a substrate to separate doses of a metal precursor, which does not contain metal-oxygen bonds, and an alcohol. These methods do not oxidize the underlying metal layer.

Abstract: Metal coordination complexes comprising at least one diazabutadiene based ligand having a structure represented by: where R1 and R4 are selected from the group consisting of C4-C10 alkyl groups; and R2 and R3 are each independently selected from the group consisting of H, C1-C6 alkyl, cycloalkyl, or aryl groups and the difference in the number of carbons in R2 and R3 is greater than or equal to 2. Processing methods using the metal coordination complexes are also described.
