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.

Abstract: Memory devices and methods of forming memory devices are described. The memory devices comprise two work-function metal layers, where one work-function layer has a lower work-function than the other work-function layer. The low work-function layer may reduce gate-induced drain leakage current losses. Methods of forming memory devices are also described.

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: Processing methods comprising selectively orthogonally growing a first material through a mask to provide an expanded first material are described. The mask can be removed leaving the expanded first material extending orthogonally from the surface of the first material. Further processing can create a self-aligned via.

Abstract: A process to selectively etch a substrate surface comprising multiple metal oxides comprising exposing the substrate surface to a halogenation agent, and then exposing the substrate surface to a ligand transfer agent. The etch rate of the metals in the multiple metal oxides is substantially uniform.

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. A layer is selectively formed on the second surface and defects of the layer are formed on the blocking layer. The defects are removed from the blocking layer on the first surface.

Abstract: Processing methods for forming iridium-containing films at low temperatures are described. The methods comprise exposing a substrate to iridium hexafluoride and a reactant to form iridium metal or iridium silicide films. Methods for enhancing selectivity and tuning the silicon content of some films are also described.

Abstract: Methods of forming a lanthanide-containing film comprising exposing a substrate surface to a lanthanide-containing precursor, a metal halide and a nitrogen precursor are described. The lanthanide-containing precursor has the general formula (CpRx)2Ln(N,N-dialkylamidinate) where Cp is a cyclopentadienyl or 6, 7 or 8 membered ring, R is H, C1-C4 alkyl, x=1 to number of C in Cp, alkyl is C1 to C4 alkyl. The metal halide deposits metal halide on the substrate surface and reacts with lanthanide-containing species to convert the lanthanide-containing species to a lanthanide halide. The nitrogen-containing precursor forms a lanthanide-metal-nitride film on the substrate surface.

Abstract: Methods for filing a feature on a substrate surface comprising depositing a conformal nitride film on the substrate surface and at least one feature on the surface, oxidizing a portion of the nitride film to form an asymmetric oxide film on top of the nitride film and etching the oxide film from the nitride film to leave a v-shaped nitride film in the at least one feature.
