Abstract
A capacitor includes a lower electrode, a first dielectric layer provided on the lower electrode including a perovskite structure, an upper electrode including a perovskite structure, a first dielectric layer between provided on the lower electrode and the upper electrode; and a second dielectric layer, having a band gap energy greater than that of the first dielectric layer, provided between on the first dielectric layer and the upper electrode, the capacitor may have a low leakage current density and stable crystallinity, thereby suppressing a decrease in a dielectric constant.
