摘要： A nonvolatile resistive memory element has a novel variable resistance layer that includes a metal nitride, a metal oxide-nitride, a two-metal oxide-nitride, or a multilayer stack thereof. One method of forming the novel variable resistance layer comprises an interlayer deposition procedure, in which metal oxide layers are interspersed with metal nitride layers and then converted into a substantially homogeneous layer by an anneal process. Another method of forming the novel variable resistance layer comprises an intralayer deposition procedure, in which various ALD processes are sequentially interleaved to form a metal oxide-nitride layer. Alternatively, a metal oxide is deposited, nitridized, and annealed to form the variable resistance layer or a metal nitride is deposited, oxidized, and annealed to form the variable resistance layer.

摘要： Embodiments of the invention generally relate to nonvolatile memory devices and methods for manufacturing such memory devices. The methods for forming improved memory devices, such as a ReRAM cells, provide optimized, atomic layer deposition (ALD) processes for forming a metal oxide film stack which contains at least one hard metal oxide film (e.g., metal is completely oxidized or substantially oxidized) and at least one soft metal oxide film (e.g., metal is less oxidized than hard metal oxide). The soft metal oxide film is less electrically resistive than the hard metal oxide film since the soft metal oxide film is less oxidized or more metallic than the hard metal oxide film. In one example, the hard metal oxide film is formed by an ALD process utilizing ozone as the oxidizing agent while the soft metal oxide film is formed by another ALD process utilizing water vapor as the oxidizing agent.

摘要： Embodiments of the invention generally relate to memory devices and methods for fabricating such memory devices. In one embodiment, a method for fabricating a resistive switching memory device includes depositing a metallic layer on a lower electrode disposed on a substrate and exposing the metallic layer to an activated oxygen source while heating the substrate to an oxidizing temperature within a range from about 300° C. to about 600° C. and forming a metal oxide layer from an upper portion of the metallic layer during an oxidation process. The lower electrode contains a silicon material and the metallic layer contains hafnium or zirconium. Subsequent to the oxidation process, the method further includes heating the substrate to an annealing temperature within a range from greater than 600° C. to about 850° C. while forming a metal silicide layer from a lower portion of the metallic layer during a silicidation process.

摘要： Systems and methods for preparing resistive switching memory devices such as resistive random access memory (ReRAM) devices wherein both oxide and nitride layers are deposited in a single chamber are provided. Various oxide and nitride based layers in the ReRAM device such as the switching layer, current-limiting layer, and the top electrode (and optionally the bottom electrode) are deposited in the single chamber. By fabricating the ReRAM device in a single chamber, throughput is increased and cost is decreased. Moreover, processing in a single chamber reduces device exposure to air and to particulates, thereby minimizing device defects.
