    摘要： A nonvolatile memory device may include a substrate having a cell region, and a cell device isolation layer on the cell region of the substrate to define a cell active region. A floating gate may include a lower floating gate and an upper floating gate sequentially stacked on the cell active region, and a tunnel insulation pattern may be between the floating gate and the cell active region. A control gate electrode may be on the floating gate, and a blocking insulation pattern may be between the control gate electrode and the floating gate. More particularly, the upper floating gate may include a flat portion on the lower floating gate and a pair of wall portions extending upward from both edges of the flat portion adjacent to the cell device isolation layer. Moreover, a width of an upper portion of a space surrounded by the flat portion and the pair of wall portions may be larger than a width of a lower portion of the space. Related methods are also discussed.

    摘要： A method of fabricating a flash memory device. Parallel mask patterns are formed on a substrate. The substrate is etched using the mask patterns to form trenches. An insulating layer pattern is formed in the trenches and an area between the mask patterns. The mask patterns are removed to expose an upper sidewall of the insulating layer pattern that protrudes away from a top surface of the substrate. The insulating layer pattern is isotropically etched to form sloped sidewalls that protrude away from the top surface of the substrate.

    摘要： In an integrated circuit device and method of manufacturing the same, a resistor pattern is positioned on a device isolation layer of a substrate. The resistor pattern includes a resistor body positioned in a recess portion of the device isolation layer and a connector making contact with the resistor body and positioned on the device isolation layer around the recess portion. The connector has a metal silicide pattern having electric resistance lower than that of the resistor body at an upper portion. A gate pattern is positioned on the active region of the substrate and includes the metal silicide pattern at an upper portion. A resistor interconnection is provided to make contact with the connector of the resistor pattern. A contact resistance between the connector and the resistor interconnection is reduced.
