Abstract
A capacitor structure characterized by improved capacitance as a result of increasing the capacitance associated with charge spreading that occurs within the electrodes of the capacitor. The electrodes are formed of superconducting or high-dielectric constant conductor materials, and are preferably used in combination with high-dielectric constant insulator materials. The capacitor structures are particularly suited as thin-film capacitors of the type used for high-density applications such as DRAM.
