    摘要: Disclosed is a method for depositing a metal layer on an interconnect structure for a semiconductor wafer. In the method, a metal conductor is covered by a dielectric layer. The dielectric layer is patterned so as to expose the metal conductor. A liner layer is then deposited into the pattern. The liner layer is then argon sputter etched to remove the liner layer and expose the metal conductor. In the process of argon sputter etching, the liner layer is redeposited onto the sidewall of the pattern. Lastly, an additional layer is deposited into the pattern and covers the redeposited liner layer.

    摘要: Substrate processing systems and methods are described for processing substrates having two or more regions. The processing includes one or more of molecular self-assembly and combinatorial processing. At least one of materials, processes, processing conditions, material application sequences, and process sequences is different for the processing in at least one region of the substrate relative to at least one other region of the substrate. Processing systems are described that include numerous processing modules. The modules include a site-isolated reactor (SIR) configured for one or more of molecular self-assembly and combinatorial processing of a substrate.

    摘要: A first electrode layer for a Metal-Insulator-Metal (MIM) DRAM capacitor is formed wherein the first electrode layer contains a conductive metal oxide formed using a high temperature, low pressure ALD process. The high temperature ALD process results in a layer with enhanced crystallinity, higher density, reduced shrinkage, and lower carbon contamination. The high temperature ALD process can be used for either or both the bottom electrode and the top electrode layers.

    摘要: Nonvolatile memory elements are provided that have resistive switching metal oxides. The nonvolatile memory elements may be formed from resistive-switching metal oxide layers. Metal oxide layers may be formed using sputter deposition at relatively low sputtering powers, relatively low duty cycles, and relatively high sputtering gas pressures. Dopants may be incorporated into a base oxide layer at an atomic concentration that is less than the solubility limit of the dopant in the base oxide. At least one oxidation state of the metal in the base oxide is preferably different than at least one oxidation sate of the dopant. The ionic radius of the dopant and the ionic radius of the metal may be selected to be close to each other. Annealing and oxidation operations may be performed on the resistive switching metal oxides. Bistable metal oxides with relatively large resistivities and large high-state-to-low state resistivity ratios may be produced.
