Abstract
A capacitor of a semiconductor device includes a lower electrode, a dielectric layer, including a plurality of band gaps, formed on the lower electrode, and an upper electrode formed on the dielectric layer. A band gap of the plurality of band gaps in the dielectric layer that is not adjacent to either the lower electrode or the upper electrode is smaller than a band gap of the plurality of band gaps in the dielectric layer adjacent to the lower electrode and a band gap of the plurality of band gaps in the dielectric layer adjacent to the upper electrode.
