  • Patent number: 9685608
    Abstract: Providing for two-terminal memory that mitigates diffusion of external material therein is described herein. In some embodiments, a two-terminal memory cell can comprise an electrode layer. The electrode layer can be at least in part permeable to ionically or chemically reactive material, such as oxygen or the like. The two-terminal memory can further comprise a diffusion mitigation material disposed between the electrode layer and external material. This diffusion mitigation material can be selected to mitigate or prevent diffusion of the undesired element(s) or compound(s), to mitigate or avoid exposure of such element(s) or compound(s) to the electrode layer. Accordingly, degradation of the two-terminal memory as a result of contact with the undesired element(s) or compound(s) can be mitigated by various disclosed embodiments.

  • Patent number: 9583701
    Abstract: A memory device comprising a doped conductive polycrystalline layer having an electrically resistive portion, is described herein. By way of example, ion implantation to a subset of the conductive polycrystalline layer can degrade and modify the polycrystalline layer, forming the electrically resistive portion. The electrically resistive portion can include resistive switching properties facilitating digital information storage. Parametric control of the ion implantation can facilitate control over corresponding resistive switching properties of the resistive portion. For example, a projected range or depth of the ion implantation can be controlled, allowing for preferential placement of atoms in the resistive portion, and fine-tuning of a forming voltage of the memory device. As another example, dose and number of atoms implanted, type of atoms or ions that are implanted, the conductive polycrystalline material used, and so forth, can facilitate control over switching characteristics of the memory device.

  • Publication number: 20160351625
    Abstract: A recessed high voltage metal oxide semiconductor (MOS) transistor is provided for use in a two-terminal memory cell. The two-terminal memory cell can include a resistive switching device connected to the recessed MOS transistor. The recessed MOS transistor provides for an increased channel length relative to the transistor size in comparison to a traditional MOS transistor. This allows for a decreased memory cell size while maintaining comparable electrical parameters (threshold voltage, channel length, and leakage) than would otherwise be possible. The recessed MOS transistor can be made as either a NMOS or PMOS device using n-type or p-type materials respectively, where the channel, or inversion layer, is formed by electrons (NMOS) or holes (PMOS) between the source and drain in the transistor.

  • Patent number: 9437814
    Abstract: During fabrication of a two-terminal memory device, a terminal (e.g., bottom terminal) can be formed. After formation of the terminal, a chemical mechanical planarization (CMP) process can be applied that, depending on the composition of the terminal, can cause damage that affect operating characteristics of the finished memory device or cell. In some embodiments, such damage can be removed by one or more post-CMP processes. In some embodiments, such damage can be mitigated so as to prevent the damage from occurring at all, by, e.g., forming a sacrificial layer atop the terminal prior to performing the CMP process. Thus, the sacrificial layer can operate to protect the terminal from damage resulting from the CMP process, with the remainder of the sacrificial layer being removed prior to completing the fabrication of the two-terminal memory device.

  • Patent number: 9425046
    Abstract: Techniques for processing silicon germanium (SiGe) thin films to reduce surface roughness thereof are provided herein. In an aspect, a method is disclosed that includes depositing a silicon germanium (SiGe) material upon a surface of a substrate at or below about 450 degrees Celsius, the substrate having a plurality of CMOS devices therein and forming, from the deposited SiGe material, a SiGe material film, wherein the SiGe material film has a jagged surface comprising projections and indentations extended along a direction substantially perpendicular to the surface of the substrate. The method further includes performing a chemical mechanical planarization (CMP) process to the jagged surface of the SiGe material, and reducing variations between the projections and the indentions along the direction substantially perpendicular to the surface of the substrate, and transforming the jagged surface of the SiGe material into a relatively smooth surface, compared to the jagged surface.
