    摘要: A non-volatile memory device having a charge trap layer and a method of fabricating the same are provided. The non-volatile memory device includes a semiconductor substrate having an active region and a field region in contact with the active region. A trench isolation layer is formed within the semiconductor substrate field region to define the active region and has a protrusion higher than a top surface of the semiconductor substrate active region. A memory storage pattern is formed which crosses and extends from the semiconductor substrate active region to cover sidewalls of the protrusion of the trench isolation layer. A gate electrode is formed on the memory storage pattern and extends upward from the trench isolation layer.

    摘要: A nonvolatile memory device includes a semiconductor substrate and a device isolation layer on the semiconductor substrate. A fin-shaped active region is formed between portions of the device isolation layer. A sidewall protection layer is formed on the sidewall of the fin-shaped active region where source and drain regions are formed. Thus, it may be possible to reduce the likelihood of an undesirable connection between an interconnection layer connected to the source and drain regions and a lower sidewall of the active region so that charge leakage from the interconnection layer to a substrate can be prevented or reduced. The sidewall protection layer may be formed using the device isolation layer. Alternatively, an insulating layer having an etch selectivity with respect to an interlayer insulating layer may be formed on the device isolation layer so as to cover the sidewall of the active region.
