Abstract
A hybrid capacitor is provided which includes a substrate, at least one plate capacitor and at least one through hole capacitor. The substrate has through holes and the plate capacitors are on the substrate. At least one through hole capacitor and at least one plate capacitor are in parallel. The through hole capacitor at least includes an anode layer, a first dielectric layer, a first cathode layer and a second cathode layer. The anode layer is disposed on an inner surface of at least one through hole, and a surface of the anode layer is a porous structure. The first dielectric layer is disposed on the porous structure of the anode layer and covered with the first cathode layer. The first cathode layer is covered with the second cathode layer. A conductivity of the second cathode layer is larger than a conductivity of the first cathode layer.
