Abstract
A capacitor component includes: a semiconductor substrate including first and second portions, a trench penetrating through the substrate from one surface of the substrate to the other surface of the substrate to separate the first and second portions of the substrate from each other, a dielectric layer disposed in the trench and on the one surface of the substrate; a first pad electrode and a second pad electrode spaced apart from each other, and penetrating through the dielectric layer to be in contact with the first and second portions of the substrate, respectively, and a passivation layer disposed on the dielectric layer, covering portions of the first pad electrode and the second pad electrode, and exposing at least a portion of each of the first pad electrode and the second pad electrode.
