    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: Threshold voltage (Vt) tuning layers may be sensitive to etching by reactants used to deposit overlying gate material, such as metal nitride. Methods for depositing Vt tuning layers are provided. In some embodiments Vt tuning layers may comprise a Vt tuning material in a neutral matrix. In some embodiments, processes for reducing or eliminating the etching of Vt tuning layers by halide reactants are described. In some embodiments a Vt tuning layer, such as a metal oxide layer, is treated by a nitridation process following deposition and prior to subsequent deposition of a metal nitride capping layer. In some embodiments an etch-protective layer, such as a NbO layer, is deposited over a Vt tuning layer prior to deposition of an overlying metal nitride layer.
