A method for making a capacitor having improved capacitance efficiency which results from increasing the effective area of an electrode surface is disclosed. Specifically, an improved 'three-dimensional' capacitor may be constructed with electrode layers having three-dimensional aspects at the point of interface with a dielectric such that portions of the electrode extend into the dielectric layer. Advantageously, embodiments of a three-dimensional capacitor drastically reduce the space footprint that is required in a circuit to accommodate the capacitor, when compared to current capacitor designs. Increased capacitance density may be realized without using high k (high constant) dielectric materials, additional 'electrode-dielectric-electrode' arrangements in an ever increasing stack, or serially stringing together multiple capacitors.
