Abstract
A capacitor that includes a substrate, a lower electrode on the substrate, a dielectric film on the lower electrode, an upper electrode on a part of the dielectric film, a protective layer that covers the lower electrode and the upper electrode, and an external electrode that penetrates the protective layer. The external electrode is formed only in a region defined by a periphery of the upper electrode in a plan view of the capacitor viewed from an upper surface thereof towards the substrate.
