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: 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: Provided are methods for the deposition of films comprising SiCN. Certain methods involve exposing a substrate surface to a silicon precursor, wherein the silicon precursor is halogenated with Cl, Br or I, and the silicon precursor comprises a halogenated silane, a halogenated carbosilane, an halogenated aminosilane or a halogenated carbo-sillyl amine. Then, the substrate surface can be exposed to a nitrogen-containing plasma or a nitrogen precursor and densification plasma.

Abstract: Embodiments include a method for forming a carbon containing film. In an embodiment, the method comprises flowing a precursor gas into a processing chamber. For example the precursor gas comprises carbon containing molecules. In an embodiment, the method further comprises flowing a co-reactant gas into the processing chamber. In an embodiment, the method further comprises striking a plasma in the processing chamber. In an embodiment plasma activated co-reactant molecules initiate polymerization of the carbon containing molecules in the precursor gas. Embodiments may also include a method that further comprises depositing a carbon containing film onto a substrate in the processing chamber.

Abstract: In some embodiments, a method of forming an interconnect structure includes selectively depositing a barrier layer atop a substrate having one or more exposed metal surfaces and one or more exposed dielectric surfaces, wherein a thickness of the barrier layer atop the one or more exposed metal surfaces is greater than the thickness of the barrier layer atop the one or more exposed dielectric surfaces. In some embodiments, a method of forming an interconnect structure includes depositing an etch stop layer comprising aluminum atop a substrate via a physical vapor deposition process; and depositing a barrier layer atop the etch stop layer via a chemical vapor deposition process, wherein the substrate is transferred from a physical vapor deposition chamber after depositing the etch stop layer to a chemical vapor deposition chamber without exposing the substrate to atmosphere.
