    摘要: A method of forming a disturb-resistant non volatile memory device includes providing a substrate and forming a first dielectric thereon, forming a first strip of material separated from a second strip of material from a first wiring material, and forming a second dielectric thereon to fill a gap between the first and second strips of material. Openings are formed in the second dielectric exposing portions of the first wiring material. Filing the openings by p+ polysilicon contact material, and then an undoped amorphous silicon material, and then a metal material. A second wiring structure is formed thereon to contact the metal material in the openings. Resistive switching cells are formed from the first wiring structure, the second wiring structure, the contact material, the undoped amorphous silicon material, and the metal material.

    摘要: A method of forming a memory device. The method provides a semiconductor substrate having a surface region. A first dielectric layer is formed overlying the surface region of the semiconductor substrate. A bottom wiring structure is formed overlying the first dielectric layer and a second dielectric material is formed overlying the top wiring structure. A bottom metal barrier material is formed to provide a metal-to-metal contact with the bottom wiring structure. The method forms a pillar structure by patterning and etching a material stack including the bottom metal barrier material, a contact material, a switching material, a conductive material, and a top barrier material. The pillar structure maintains a metal-to-metal contact with the bottom wiring structure regardless of the alignment of the pillar structure with the bottom wiring structure during etching. A top wiring structure is formed overlying the pillar structure at an angle to the bottom wiring structure.

    摘要: In a novel nonvolatile memory cell formed above a substrate, a diode is paired with a reversible resistance-switching material, preferably a metal oxide or nitride such as, for example, NixOy, NbxOy, TixOy, HfxOy, AlxOy, MgxOy, CoxOy, CrxOy, VxOy, ZnxOy, ZrxOy, BxNy, and AlxNy. In preferred embodiments, the diode is formed as a vertical pillar disposed between conductors. Multiple memory levels can be stacked to form a monolithic three dimensional memory array. In some embodiments, the diode comprises germanium or a germanium alloy, which can be deposited and crystallized at relatively low temperatures, allowing use of aluminum or copper in the conductors. The memory cell of the present invention can be used as a rewriteable memory cell or a one-time-programmable memory cell, and can store two or more data states.
