Abstract
A semiconductor device includes a capacitor structure. The capacitor structure includes a bottom electrode, a dielectric layer, and a top electrode that are sequentially stacked in a first direction. The dielectric layer includes first dielectric layers and second dielectric layers interposed between the bottom electrode and the top electrode and are that are alternately stacked in the first direction. The first dielectric layers include a ferroelectric material, and the second dielectric layers include an anti-ferroelectric material. A lowermost second dielectric layer is interposed between a lowermost first dielectric layer and the bottom electrode, and an uppermost second dielectric layer is interposed between an uppermost first dielectric layer and the top electrode.
