Abstract

A capacitor includes a first electrode and a second electrode spaced apart from each other, a dielectric layer disposed between the first electrode and the second electrode, and a seed layer disposed between the first electrode and the dielectric layer. The dielectric layer includes a dielectric material having a tetragonal crystal structure. The seed layer includes a seed material that satisfies at least one of a lattice constant condition or a bond length condition.
