    摘要: A semiconductor device includes gate structures including a tunnel insulating layer pattern, a floating gate, a dielectric layer pattern and a control gate sequentially disposed on a substrate. The control gate includes an impurity doped polysilicon layer pattern and a metal layer pattern. The gate structures are spaced apart from each other on the substrate. A capping layer pattern is disposed on a sidewall portion of the metal layer pattern and includes a metal oxide. An insulating layer covers the gate structures and the capping layer pattern. The insulating layer is formed on the substrate and includes an air-gap therein.

    摘要: A nonvolatile memory device may include: a tunnel insulating layer on a semiconductor substrate; a charge storage layer on the tunnel insulating layer; a blocking insulating layer on the charge storage layer; and a control gate electrode on the blocking insulating layer. The tunnel insulating layer may include a first tunnel insulating layer and a second tunnel insulating layer. The first tunnel insulating layer and the second tunnel insulating layer may be sequentially stacked on the semiconductor substrate. The second tunnel insulating layer may have a larger band gap than the first tunnel insulating layer. A method for fabricating a nonvolatile memory device may include: forming a tunnel insulating layer on a semiconductor substrate; forming a charge storage layer on the tunnel insulating layer; forming a blocking insulating layer on the charge storage layer; and forming a control gate electrode on the blocking insulating layer.

    摘要: In a method of manufacturing a non-volatile memory device, a tunnel insulating layer may be formed on a channel region of a substrate. A charge trapping layer including silicon nitride may be formed on the tunnel insulating layer to trap electrons from the channel region. A heat treatment may be performed using a first gas including nitrogen and a second gas including oxygen to remove defect sites in the charge trapping layer and to densify the charge trapping layer. A blocking layer may be formed on the heat-treated charge trapping layer, and a conductive layer may then formed on the blocking layer. The blocking layer, the conductive layer, the heat-treated charge trapping layer and the tunnel insulating layer may be patterned to form a gate structure on the channel region. Accordingly, data retention performance and/or reliability of a non-volatile memory device including the gate structure may be improved.
