    摘要: A charge trap memory device may include a tunnel insulating layer formed on a substrate. A charge trap layer may be formed on the tunnel insulating layer, wherein the charge trap layer is a higher-k dielectric insulating layer doped with one or more transition metals. The tunneling insulating layer may be relatively non-reactive with respect to metals in the charge trap layer. The tunneling insulating layer may also reduce or prevent metals in the charge trap layer from diffusing into the substrate.

    摘要: Provided is a nonvolatile semiconductor memory device and a method of manufacturing the same. The nonvolatile semiconductor memory device may include a tunnel insulating layer formed on a semiconductor substrate, a charge trap layer including a dielectric layer doped with a transition metal formed on the tunnel insulating layer, a blocking insulating layer formed on the charge trap layer, and a gate electrode formed on the blocking insulating layer. The dielectric layer may be a high-k dielectric layer, for example, a HfO2 layer. Thus, the data retention characteristics of the nonvolatile semiconductor memory device may be improved because a deeper charge trap may be formed by doping the high-k dielectric layer with a transition metal.
