    摘要: Complementary metal oxide semiconductor (CMOS) static random access memory (SRAM) cells include at least a first inverter formed in a fin-shaped pattern of stacked semiconductor regions of opposite conductivity type. In some of these embodiments, the first inverter includes a first conductivity type (e.g., P-type or N-type) MOS load transistor electrically coupled in series with a second conductivity type (e.g., N-type of P-type) MOS driver transistor. The first inverter is arranged so that active regions of the first conductivity type MOS load transistor and the second conductivity type driver transistor are vertically stacked relative to each other within a first portion of a vertical dual-conductivity semiconductor fin structure. This fin structure is surrounded on at least three sides by a wraparound gate electrode, which is configured to modulate conductivity of both the active regions in response to a gate signal.

    摘要: Methods of forming carbon nanotubes include forming a catalytic metal layer on a sidewall of an electrically conductive region, such as a metal or metal nitride pattern. A plurality of carbon nanotubes are grown from the catalytic metal layer. These carbon nanotubes can be grown from a sidewall of the catalytic metal layer. The plurality of carbon nanotubes are then exposed to an organic solvent. This step of exposing the carbon nanotubes to the organic solvent may be preceded by a step of applying centrifugal forces to the plurality of carbon nanotubes. Alternatively, the exposing step may include applying a centrifugal force to the plurality of carbon nanotubes while simultaneously exposing the plurality of carbon nanotubes to an organic solvent.

    摘要: In a DRAM device and a method of manufacturing the same, a multiple tunnel junction (MTJ) structure is provided, which includes conductive patterns and nonconductive patterns alternately stacked on each other. The nonconductive patterns have a band gap larger than a band gap of the conductive patterns. A gate insulation layer and a gate electrode are formed on a sidewall of the MTJ structure. A word line is connected with the MTJ structure, and a bit line is connected with one of top and bottom surfaces of the MTJ structure. A capacitor is connected with one of top and bottom surfaces of the MTJ structure that is not connected with the bit line. Current leakage in the DRAM device is reduced and a unit cells may be vertically stacked on the substrate, so a smaller surface area of the substrate is required for the DRAM device.
