    摘要: In a semiconductor memory device and method, resistive-change memory cells are provided, each including a plurality of control transistors formed on different layers and variable resistance devices comprising a resistive-change memory. Each resistive-change memory cell includes a plurality of control transistors formed on different layers, and a variable resistance device formed of a resistive-change memory. In one example, the number of the control transistors is two. The semiconductor memory device includes a global bit line; a plurality of local bit lines connected to or disconnected from the global bit line via local bit line selection circuits which correspond to the local bit lines, respectively; and a plurality of resistive-change memory cell groups storing data while being connected to the local bit lines, respectively. Each of the resistive-change memory cells of each of the resistive-change memory cell groups comprises a plurality of control transistors formed on different layers, and a variable resistance device formed of a resistive-change memory. In addition, the semiconductor memory device has a hierarchical bit line structure that uses a global bit line and local bit lines. Accordingly, it is possible to increase both the integration density of the semiconductor memory device and the amount of current flowing through each of the resistive-change memory cells.

    摘要: A multi-bridge-channel MOSFET (MBCFET) may be formed by forming a stacked structure on a substrate that includes channel layers and interchannel layers interposed between the channel layers. Trenches are formed by selectively etching the stacked structure. The trenches run across the stacked structure parallel to each other and separate a first stacked portion including channel patterns and interchannel patterns from second stacked portions including channel and interchannel layers remaining on both sides of the first stacked portion. First source and drain regions are grown using selective epitaxial growth. The first source and drain regions fill the trenches and connect to second source and drain regions defined by the second stacked portions. Marginal sections of the interchannel patterns of the first stacked portion are selectively exposed. Through tunnels are formed by selectively removing the interchannel patterns of the first stacked portion beginning with the exposed marginal sections. The through tunnels are surrounded by the first source and drain regions and the channel patterns. A gate is formed along with a gate dielectric layer, the gate filling the through tunnels and extending onto the first stacked portion.

    摘要: In a method of manufacturing a semiconductor device, a preliminary active pattern including gate layers and channel layers is formed on a substrate. The gate layers and the channel layers are alternatively stacked. A hard mask is formed on the preliminary active pattern. The preliminary active pattern is partially etched using the hard mask as an etching mask to expose a surface of the substrate. The etched preliminary active pattern is trimmed to form an active channel pattern having a width less than a lower width of the hard mask. Source/drain layers are formed on exposed side faces of the active channel pattern and the surface. The gate layers are selectively etched to form tunnels. A gate encloses the active channel pattern and filling the tunnels. Related intermediate structures are also disclosed.

    摘要: A gate-all-around (GAA) transistor device has a pair of pillars that include the source/drain regions, a channel region bridging the source/drain regions, and a gate electrode and gate oxide which surround the channel region. The pillars are formed by providing a mono-crystalline silicon substrate, etching the substrate to form a pair of spaced-apart trenches such that a wall of the mono-crystalline silicon stands between the trenches, filling the trenches with insulative material, implanting impurities into the wall of mono-crystalline silicon, and forming an opening in the wall such that portions of the wall remain as pillars. A sacrificial layer is formed at the bottom of the opening. Then, the channel region is formed atop the sacrificial layer between the pillars. The sacrificial layer is subsequently removed and the gate oxide and gate electrode are formed around the channel region. One or more sidewall spacers are used to establish the effective width of the channel region and/or minimize parasitic capacitance between the source/drain regions and gate electrode.
