Abstract: Processes are provided herein for deposition of organic films. Organic films can be deposited, including selective deposition on one surface of a substrate relative to a second surface of the substrate. For example, polymer films may be selectively deposited on a first metallic surface relative to a second dielectric surface. Selectivity, as measured by relative thicknesses on the different layers, of above about 50% or even about 90% is achieved. The selectively deposited organic film may be subjected to an etch process to render the process completely selective. Processes are also provided for particular organic film materials, independent of selectivity. Masking applications employing selective organic films are provided. Post-deposition modification of the organic films, such as metallic infiltration and/or carbon removal, is also disclosed.

Abstract: In some aspects, methods of forming a metal sulfide thin film are provided. According to some methods, a metal sulfide thin film is deposited on a substrate in a reaction space in a cyclical process where at least one cycle includes alternately and sequentially contacting the substrate with a first vapor-phase metal reactant and a second vapor-phase sulfur reactant. In some aspects, methods of forming a three-dimensional architecture on a substrate surface are provided. In some embodiments, the method includes forming a metal sulfide thin film on the substrate surface and forming a capping layer over the metal sulfide thin film. The substrate surface may comprise a high-mobility channel.

Abstract: A method for improving source/drain performance through conformal solid state doping and its resulting device are disclosed. Specifically, the doping takes place through an atomic layer deposition of a dopant layer. Embodiments of the invention may allow for an increased doping layer, improved conformality, and reduced defect formation, in comparison to alternate doping methods, such as ion implantation or epitaxial doping.

Abstract: A process for depositing aluminum nitride is disclosed. The process comprises providing a plurality of semiconductor substrates in a batch process chamber and depositing an aluminum nitride layer on the substrates by performing a plurality of deposition cycles without exposing the substrates to plasma during the deposition cycles. Each deposition cycle comprises flowing an aluminum precursor pulse into the batch process chamber, removing the aluminum precursor from the batch process chamber, and removing the nitrogen precursor from the batch process chamber after flowing the nitrogen precursor and before flowing another pulse of the aluminum precursor. The process chamber may be a hot wall process chamber and the deposition may occur at a deposition pressure of less than 1 Torr.
