A semiconductor-based capacitor can include a substrate including a semiconductor material, an oxide layer formed over the substrate, a conductive layer formed over at least a portion of the oxide layer, a plurality of distinct coplanar upper terminals, and a lower terminal. The upper terminals and the lower terminal can be exposed along the top and bottom surfaces of the substrate, respectively, for embedding the capacitor in a substrate such as a circuit board. The semiconductor-based capacitor can be sufficiently miniaturized to be embeddable within a circuit board while providing superior capacitance values without compromising the integrity of the capacitor. For example, each of the upper terminals can have a maximum width and a thickness normal to the maximum width, and a ratio of the width to the thickness can be greater than about 80:1 to prevent physical damage to the capacitor from warping or cracking.
