    Abstract: Resistive switching memory elements are provided that may contain electroless metal electrodes and metal oxides formed from electroless metal. The resistive switching memory elements may exhibit bistability and may be used in high-density multi-layer memory integrated circuits. Electroless conductive materials such as nickel-based materials may be selectively deposited on a conductor on a silicon wafer or other suitable substrate. The electroless conductive materials can be oxidized to form a metal oxide for a resistive switching memory element. Multiple layers of conductive materials can be deposited each of which has a different oxidation rate. The differential oxidization rates of the conductive layers can be exploited to ensure that metal oxide layers of desired thicknesses are formed during fabrication.

    Abstract: Embodiments of the invention generally include a method of forming a nonvolatile memory device that contains a resistive switching memory element that has an improved device switching performance and lifetime, due to the addition of a current limiting component disposed therein. In one embodiment, the current limiting component comprises at least one layer of resistive material that is configured to improve the switching performance and lifetime of the formed resistive switching memory element. The electrical properties of the formed current limiting layer, or resistive layer, are configured to lower the current flow through the variable resistance layer during the logic state programming steps (i.e., “set” and “reset” steps) by adding a fixed series resistance in the formed resistive switching memory element found in the nonvolatile memory device. Typically, resistive switching memory elements may be formed as part of a high-capacity nonvolatile memory integrated circuit, which can be used in various electronic devices, such as digital cameras, mobile telephones, handheld computers, and music players.

    Abstract: Selector devices that can be suitable for memory device applications can have low leakage currents at low voltages to reduce sneak current paths for non selected devices, and high leakage currents at high voltages to minimize voltage drops during device switching. In some embodiments, the selector device can include a first electrode, a tri-layer dielectric layer, and a second electrode. The tri-layer dielectric layer can include a high leakage dielectric layer sandwiched between two lower leakage dielectric layers. The low leakage layers can function to restrict the current flow across the selector device at low voltages. The high leakage dielectric layer can function to enhance the current flow across the selector device at high voltages.

    Abstract: Methods and apparatus for processing using a remote plasma source are disclosed. The apparatus includes an outer chamber, a remote plasma source, and a showerhead. Inert gas ports within the showerhead assembly can be used to alter the concentration and energy of reactive radical or reactive neutral species generated by the remote plasma source in different regions of the showerhead. This allows the showerhead to be used to apply a surface treatment to different regions of the surface of a substrate. Varying parameters such as the remote plasma parameters, the inert gas flows, pressure, and the like allow different regions of the substrate to be treated in a combinatorial manner.

    Abstract: In embodiments of the current invention, methods of combinatorial processing and a test chip for use in these methods are described. These methods and test chips enable the efficient development of materials, processes, and process sequence integration schemes for semiconductor manufacturing processes. In general, the methods simplify the processing sequence of forming devices or partially formed devices on a test chip such that the devices can be tested immediately after formation. The immediate testing allows for the high throughput testing of varied materials, processes, or process sequences on the test chip. The test chip has multiple site isolated regions where each of the regions is varied from one another and the test chip is designed to enable high throughput testing of the different regions.

    Abstract: Embodiments of the invention generally relate to nonvolatile memory devices, such as a ReRAM cells, and methods for manufacturing such memory devices, which includes optimized, atomic layer deposition (ALD) processes for forming metal oxide film stacks. The metal oxide film stacks contain a metal oxide coupling layer disposed on a metal oxide host layer, each layer having different grain structures/sizes. The interface disposed between the metal oxide layers facilitates oxygen vacancy movement. In many examples, the interface is a misaligned grain interface containing numerous grain boundaries extending parallel to the electrode interfaces, in contrast to the grains in the bulk film extending perpendicular to the electrode interfaces. As a result, oxygen vacancies are trapped and released during switching without significant loss of vacancies. Therefore, the metal oxide film stacks have improved switching performance and reliability during memory cell applications compared to traditional hafnium oxide based stacks of previous memory cells.
