    Abstract: A semiconductor device may include a substrate including an active pattern extending in a first direction, a gate electrode extending in a second direction and crossing the active pattern, a gate capping pattern covering a top surface of the gate electrode, and a separation structure at a side of the gate electrode and extending in the second direction to penetrate the active pattern in a third direction. The first and second directions are parallel to a bottom surface of the substrate and are perpendicular to the third direction. The separation structure may include a filling pattern, which extends in the third direction to penetrate the active pattern, and a vertical insulating pattern, which is interposed between the filling pattern and the gate electrode. A top surface of the separation structure may be located at a height lower than a top surface of the gate capping pattern.

    Abstract: A semiconductor device may include a substrate, a patterned structure, a filling pattern, and a conductive spacer. The substrate may include a semiconductor chip region and an overlay region. The patterned structure may include bit line structures spaced by a first distance on the semiconductor region, define a first trench and a second trench on first and second regions of the overlay region, and include key structures on the second region and spaced apart by the second trench. The filling pattern may fill lower portions of the first and second trenches on the first and second regions. The first region may be an edge portion of the overlay region. The second region may be a central portion of the overlay region. The conductive spacer may contact an upper surface of the filling pattern and may be on an upper sidewall of each of the first and second trenches.

    Abstract: A method of manufacturing a semiconductor device includes forming on a substrate gate electrodes extending in a first direction and spaced apart from each other in a second direction, forming capping patterns on the gate electrodes, forming interlayer dielectric layer filling spaces between adjacent gate electrodes, forming a hardmask on the interlayer dielectric layer with an opening selectively exposing second to fourth capping patterns, using the hardmask as an etch mask to form holes in the interlayer dielectric layer between the second and third gate electrodes and between the third and fourth gate electrodes, forming a barrier layer and a conductive layer in the holes, performing a first planarization to expose the hardmask, performing a second planarization to expose a portion of the barrier layer covering the second to fourth capping patterns, and performing a third planarization to completely expose the first to fourth capping patterns.

    Abstract: Provided are a three-dimensional semiconductor memory device and a method of fabricating the same. The device may include a substrate including a peripheral circuit region and a cell array region, peripheral gate stacks provided on the peripheral circuit region of the substrate, and an electrode structure provided on the cell array region of the substrate. The electrode structure may include a lower electrode, a lower insulating layer covering the lower electrode, and upper electrodes and upper insulating layers, which are vertically and alternately stacked on the lower insulating layer. The lower insulating layer may be extended from the cell array region to the peripheral circuit region to cover the peripheral gate stacks, and a top surface of the lower insulating layer may be higher on the peripheral circuit region than on the cell array region.
