Abstract

A capacitor includes a conductive substrate having a front side and a back side, a pre-drilled via that runs from the front side of the conductive substrate to the back side of the conductive substrate, a dielectric layer on the conductive substrate, a conductive polymer layer on the dielectric layer, a first metal contact electrically connected to the conductive substrate, and a second metal contact electrically isolated from the first metal contact and electrically connected to the conductive polymer on both sides of the conductive substrate through the pre-drilled via, the first and second metal contacts being formed on the front side of the conductive substrate. A portion of the conductive substrate may be removed to leave the capacitor structurally connected only by the insulating material to an adjacent device formed on the same conductive substrate.
