    摘要: Provided are a nonvolatile memory device and a method of manufacturing the same. A floating gate electrode of the nonvolatile memory device may have a cross-shaped section as taken along a direction extending along a control gate electrode. The floating gate electrode may have an inverse T-shaped section as taken along a direction extending along an active region perpendicular to the control gate electrode. The floating gate electrode may include a lower gate pattern, a middle gate pattern and an upper gate pattern sequentially disposed on a gate insulation layer, in which the middle gate pattern is larger in width than the lower gate pattern and the upper gate pattern. A boundary between the middle gate pattern and the upper gate pattern may have a rounded corner.

    摘要: Methods of fabricating a semiconductor device are provided. Methods of forming a finer pattern of a semiconductor device using a buffer layer for retarding, or preventing, bridge formation between patterns in the formation of a finer pattern below resolution limits of a photolithography process by double patterning are also provided. A first hard mask layer and/or a second hard mask layer may be formed on a layer of a substrate to be etched. A first etch mask pattern of a first pitch may be formed on the second hard mask layer. After a buffer layer is formed on the overall surface of the substrate, a second etch mask pattern of a second pitch may be formed thereon in a region between the first etch mask pattern. The buffer layer may be anisotropically etched using the second etch mask pattern as an etch mask, forming a buffer layer pattern. The second hard mask layer may be anisotropically etched using the first etch mask pattern and/or the buffer layer pattern as etch masks, forming a second hard mask pattern. The first hard mask layer may be anisotropically etched using the second hard mask pattern as an etch mask, forming a first hard mask pattern. The etched layer may be anisotropically etched using the first hard mask pattern as an etch mask.

    摘要: In a method for forming a semiconductor device and a semiconductor device having an overlay mark, a first pattern for the semiconductor device is formed in a semiconductor device formation region of a semiconductor substrate and simultaneously in a first mark formation region of the semiconductor substrate. A second pattern for the semiconductor device is formed on a resultant structure in the semiconductor device formation region of the semiconductor substrate and simultaneously in a second mark formation region of the semiconductor substrate. The first and second patterns in the first and second mark formation regions, respectively, are inspected for misalignments using overlay marks formed to have shapes and sizes identical to those of real patterns in the semiconductor device formation region of the semiconductor substrate. By measuring misalignments of real patterns using the overlay marks, overlay mismatch between the semiconductor device formation region and the overlay mark may be prevented.

    摘要: An apparatus for manufacturing a semiconductor device and a method for manufacturing a semiconductor device using the apparatus may be provided. The manufacturing apparatus may include a liquid supplying portion for forming a liquid film, and a gas supplying unit that may rotate to discharge gas at a wide range of angles. The manufacturing method may include forming a shape and size of a liquid film common to the shape and size of an exposure region through adjusting the direction and pressure in which gas may be discharged to the substrate. Thus, the speed at which a substrate may be moved may be increased, and morphology differences of a substrate may be reduced.
