Abstract
Methods of manufacturing semiconductor devices including multilayer dielectric layers are disclosed. The methods include forming a multilayer dielectric layer including metal atoms and silicon atoms on a semiconductor substrate. The multilayer dielectric layer includes at least two crystalline metal silicate layers having different silicon concentrations. The multilayer dielectric layer may be used, for example, as a dielectric layer for a capacitor, or as a blocking layer for a nonvolatile memory device.
