Abstract
A capacitor assembly includes a first electrode, a second electrode, a dielectric portion, a body and a conductive cover. The second electrode overlaps the first electrode. The dielectric portion is interposed between the first and second electrodes. The body surrounds an outer surface of the dielectric portion, the first electrode and the second electrode, and partially exposes end portions of the first and second electrodes. The conductive cover covers a side surface of the body, and has a greater width than a width of each of the end portions of the first and second electrodes. Therefore, yield of the capacitor assembly is increased, and defects are decreased.
