    Abstract: The disclosed technology generally relates to the field of semiconductor processing and more particularly to resistive random access memory and methods for manufacturing such memory. In one aspect, a method of fabricating a memory cell includes providing a substrate and providing a first electrode on the substrate. The method additionally includes depositing, via atomic layer deposition, a resistive switching material on the first electrode, wherein the resistive switching material comprises an oxide comprising a pnictogen chosen from the group consisting of As, Bi, Sb, and P. The resistive switching material may be doped, e.g., with Sb or an antimony-metal alloy. A second electrode may be formed over and in contact with the resistive switching material.

    Abstract: In some embodiments, an oxide layer is grown on a semiconductor substrate by oxidizing the semiconductor substrate by exposure to hydrogen peroxide at a process temperature of about 500° C. or less. The exposure to the hydrogen peroxide may continue until the oxide layer grows by a thickness of about 1 Å or more. Where the substrate is a germanium substrate, while oxidation using H2O has been found to form germanium oxide with densities of about 4.25 g/cm3, oxidation according to some embodiments can form an oxide layer with a density of about 6 g/cm3 or more (for example, about 6.27 g/cm3). In some embodiments, another layer of material is deposited directly on the oxide layer. For example, a dielectric layer may be deposited directly on the oxide layer.

    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.
