    Abstract: A method of fabricating nonvolatile memory devices may involve forming separate floating gates on a semiconductor substrate, forming control gates on the semiconductor substrate, conformally forming a buffer film on a surface of the semiconductor substrate, injecting ions into the semiconductor substrate between the pairs of the floating gates to form a common source region partially overlapping each floating gate of the respective pair of the floating gates, depositing an insulating film on the buffer film, etching the buffer film and the insulating film at side walls of the floating gates and the control gates to form spacers at the side walls of the floating gates and the control gates, and forming a drain region in the semiconductor substrate at a side of the control gate other than a side of the control gate where the common source region is formed.

    Abstract: Example embodiments may provide a nonvolatile memory device. The example embodiment nonvolatile memory device may include a floating gate structure formed on a semiconductor substrate with a gate insulating layer between them and/or a control gate formed adjacent to the floating gate with a tunneling insulation layer between them. The floating gate may include a first floating gate formed on the gate insulating layer, a second floating gate formed on the first floating gate with a first insulating pattern between them, and/or a gate connecting layer formed on at least one sidewall of the first insulating pattern so that the gate conducting layer may electrically connect the first floating gate and the second floating gate. The second floating gate may have a tip formed at its longitudinal end that may not contact the gate connecting layer.

    Abstract: A method of fabricating a flash memory cell having a split gate structure. A sacrificial layer is formed on a floating gate layer formed on a semiconductor substrate. The sacrificial layer is etched to form an opening exposing a portion of the floating gate layer. A gate interlayer insulating layer pattern is formed inside the opening. After removing the sacrificial layer pattern and etching the floating gate layer (using the gate interlayer insulating layer pattern as an etch mask), a floating gate is formed under the gate interlayer insulating layer pattern. A control gate is formed overlapping a portion of the floating gate.

    Abstract: A semiconductor device includes a substrate divided into a memory cell region and a logic region. A split gate electrode structure is formed in a memory cell region of a substrate. A silicon oxide layer is formed on a sidewall of the split gate electrode structure and a surface of the substrate. A word line is formed on the silicon oxide layer that is positioned on the sidewall of the split gate electrode structure. The word line has an upper width and a lower width. The lower width is greater than the upper width. A logic gate pattern is formed on a logic region of the substrate. The logic gate pattern has a thickness thinner than the lower width of the word line.
