Abstract: Aspects of this disclosure relate to selective removal of material of a layer, such as a carbon-containing layer. The layer can be over a patterned structure of two different materials. Treating the layer to cause the removal agent to be catalytically activated by a first area of the patterned structure to remove material of the organic material over the first area at a greater rate than over a second area of the patterned structure having a different composition from the first area.

Abstract: Vapor deposition methods for depositing transition metal dichalcogenide (TMDC) films, such as rhenium sulfide thin films, are provided. In some embodiments TMDC thin films are deposited using a deposition cycle in which a substrate in a reaction space is alternately and sequentially contacted with a vapor phase transition metal precursor, such as a transition metal halide, a reactant comprising a reducing agent, such as NH3 and a chalcogenide precursor. In some embodiments rhenium sulfide thin films are deposited using a vapor phase rhenium halide precursor, a reducing agent and a sulfur precursor. The deposited TMDC films can be etched by chemical vapor etching using an oxidant such as O2 as the etching reactant and an inert gas such as N2 to remove excess etching reactant. The TMDC thin films may find use, for example, as 2D materials.

Abstract: Atomic layer deposition (ALD) processes for forming Group VA element containing thin films, such as Sb, Sb—Te, Ge—Sb and Ge—Sb—Te thin films are provided, along with related compositions and structures. Sb precursors of the formula Sb(SiR1R2R3)3 are preferably used, wherein R1, R2, and R3 are alkyl groups. As, Bi and P precursors are also described. Methods are also provided for synthesizing these Sb precursors. Methods are also provided for using the Sb thin films in phase change memory devices.

Abstract: Vapor deposition processes for forming thin films comprising gold on a substrate in a reaction space are provided. The processes can be cyclical vapor deposition processes, such as atomic layer deposition (ALD) processes. The processes can include contacting the substrate with a gold precursor comprising at least one sulfur donor ligand and at least one alkyl ligand, and contacting the substrate with a second reactant comprising ozone. The deposited thin films comprising gold can be uniform, continuous, and conductive at very low thicknesses.
