1. A capacitor comprising:
a lower electrode;
an upper electrode apart from the lower electrode; and
a dielectric between the lower electrode and the upper electrode, the dielectric comprising a dielectric layer including TiO2, and a leakage current reducing layer including GeO2 in the dielectric layer such that the TiO2 is above and below the leakage current reducing layer,
wherein the leakage current reducing layer has at least one of a rutile phase or an amorphous phase.
