Method of making a capacitor

A method of making a capacitor, the method comprising:

• providing a conductive substrate having a front side and a back side and having a dielectric layer formed on the front side and the back side;
• drilling a via from the front side of the conductive substrate to the back side of the conductive substrate;
• applying a conductive polymer layer on the dielectric layer, the conductive polymer layer extending from the front side to the back side of the conductive substrate through the via to fill the via;
• producing a through via by removing the conductive polymer layer from the via to separate the conductive polymer layer into a front portion on the front side of the conductive substrate and a back portion on the back side of the conductive substrate, the front and back portions of the conductive polymer layer being electrically isolated from each other;
• filling the through via with an insulating material;
• removing a portion of the insulating material from the through via;
• forming a first metal contact electrically connected to the conductive substrate;
• and
• forming a second metal contact electrically isolated from the first metal contact and electrically connected to the first and second portions of the conductive polymer layer by the through via.
