US 5,844,770 A · Capacitor structures with dielectric coated conductive substrates

Abstract

One aspect of the present invention is directed to a capacitor. The capacitor includes a first layer and a second layer. The first layer includes a first electrically conductive substrate having a first surface and a second surface. A first dielectric film is deposited on the first surface of the first substrate and a second dielectric film is deposited on the second surface of the first substrate. The second layer contacts the first layer. The second layer includes a second electrically conductive substrate having a first surface and a second surface. A third dielectric film is deposited on the first surface of the second substrate, and a fourth dielectric film is deposited on the second surface of the second substrate.
