    摘要: In an embodiment, a chemical mechanical polishing method for a substrate having a first layer and a stepped portion. A surface of the first layer is positioned above an upper face of the stepped portion. A polishing process for selectively removing the stepped portion is performed on the first layer by using a first slurry composition that has a self-stopping characteristic so that the first layer is changed into a second layer having a substantially flat surface. A second polishing process is performed using a second slurry composition that does not have the self-stopping characteristic, until the upper face of the stepped portion is exposed.

    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 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: A method of fabricating a semiconductor device including sequentially forming a polysilicon layer, a first insulating layer, and a photoresist layer over a gate oxide film positioned on a semiconductor substrate. A photoresist pattern with a first groove is formed by selectively patterning the photoresist layer to partially expose a surface of the first insulating layer. A second insulating layer is formed over the photoresist pattern with the first groove and over the exposed surface of the first insulating layer. A sacrificial spacer is formed on each inner wall of the first groove by etching back the second insulating layer and forming a second groove in the first insulating layer in communication with the first groove to expose a surface of the polysilicon layer at the bottom of the second groove. The photoresist pattern is removed, and an arbitrary layer pattern is formed over the polysilicon layer at the bottom of the second groove. The sacrificial spacers and first insulating layer are removed, and a gate electrode is formed by etching the polysilicon layer using the arbitrary layer pattern as a mask.
