摘要:
A metamaterial coupled antenna includes a metamaterial and a rectenna that has an antenna element and a diode coupled by a transmission line. The metamaterial generates a spoof surface plasmon in the presence of heat. The antenna element resonates in the presence of the spoof surface plasmon as terahertz frequencies and generates a voltage that is coupled to the diode via the transmission line. The diode rectifies the voltage to produce electricity. The transmission line is configured to provide a voltage boost to the voltage signal delivered by the antenna element and to compensation for diode capacitance.

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.
