    Abstract: A capacitor of a memory device includes dielectric layers with different energy band gaps. The capacitor may include, for example, a first electrode and a first dielectric layer on the first electrode. The capacitor may further include a second dielectric layer on the first dielectric layer. The first and second dielectric layers may include the same dielectric material with different concentration of an impurity therein. A second electrode is disposed on the second dielectric layer.

    Abstract: A semiconductor device includes a capacitor with reduced oxygen defects at an interface between a dielectric layer and an electrode of the capacitor. The semiconductor device includes a lower metal layer; a dielectric layer on the lower metal layer and containing a first metal; a sacrificial layer on the dielectric layer and containing a second metal; and an upper metal layer on the sacrificial layer. An electronegativity of the second metal in the sacrificial layer is greater than an electronegativity of the first metal in the dielectric layer.
