    摘要: In a method of manufacturing a flash memory device, an insulation layer pattern is formed on a substrate having cell and peripheral regions. Trenches formed in the substrate are converted into trench structures. A tunnel oxide layer is formed on the substrate. A space between the trench structures is filled with a first conductive layer. The trench structures are removed to form trench isolation structures and to convert the first conductive layer into a first conductive layer pattern. A dielectric layer is formed on the first conductive layer patterns and the trench isolation structures. An insulation layer is formed on the substrate in the peripheral region. A third conductive layer is formed on the second conductive layer, the insulation layer and the trench isolation layers. First and second gate structures are formed in the cell region and the peripheral region, respectively.

    摘要: A Local interconnection wiring structure method for forming the same reduces the likelihood of a short between a local interconnection layer of gate electrodes and an active region by forming a common aperture so as to have a determined aperture between the local interconnection layer and the active region on an insulation film of a semiconductor substrate. Methods of forming the local interconnection wire can include forming a first etching mask pattern that has a size longer than a length between inner ends of adjacent gate electrodes formed on a semiconductor substrate and covered with an insulation film. The etching mask simultaneously has a length the same as or shorter than the length between outer ends of the gate electrodes. The insulation film exposed in the first etching mask pattern is subsequently etched so that the insulation film remains higher than a highest height of the gate electrodes, so as to form a recess pattern. The first etching mask pattern is then removed and a second etching mask pattern is formed so as to partially expose the insulation film provided within the recess pattern. The insulation film within the recess pattern is etched to form apertures for exposing a partial surface of the gate electrodes. The second etching mask pattern is then removed. The recess pattern and the apertures are then filled with conductive material to form a local interconnection layer for connecting between the gate electrodes.

    摘要: In a 6F2 cell structure of a memory device and a method of fabricating the same, the plurality of active regions may have a first area at both end portions and a second area at a central portion. A portion of a bit-line contact pad may be positioned on the second area and the other portion may be positioned on a third area of the substrate that may not overlap with the plurality of active regions. The bit line may be connected with the bit-line contact pad at the third area. The cell structure may be more easily formed despite a 6F2-structured unit cell. The plurality of active regions may have an elliptical shape including major and minor axes. The plurality of active regions may be positioned in a major axis direction to thereby form an active row, and may be positioned in a minor axis direction in such a structure that a center of the plurality of active regions is shifted from that of an adjacent active region in a neighboring active row.

    摘要: A slurry composition includes about 4.25 to about 18.5 weight percent of an abrasive, about 80 to about 95 weight percent of deionized water, and about 0.05 to about 1.5 weight percent of an additive. The slurry composition may further include a surfactant. In a polishing method using the slurry composition, a polysilicon layer may be rapidly polished, and also dishing and erosion of the polysilicon layer may be suppressed.
