    Abstract: A method of fabricating a semiconductor device includes forming first gate patterns on a semiconductor substrate using an etch mask pattern, forming a trench in the semiconductor substrate between the first gate patterns, forming an insulating layer in the trench, such that the insulating layer fills the trench and is disposed on the etch mask pattern, planarizing the insulating layer until a top surface of the etch mask pattern is exposed, etching a portion of the planarized insulating layer to form a device isolation layer in the trench, forming a second gate layer covering the etch mask pattern and disposed on the device isolation pattern, and planarizing the second gate layer until the top surface of the etch mask pattern is exposed, such that a second gate pattern is formed.

    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.
