Abstract
Abstract Capacitors and methods of making capacitors in which a support layer of strong material is used to support the conductive and dielectric layer of the capacitor and wherein the support layer does not lie in the electric field of the capacitor. The support layers have a coating of the same material as the dielectric to aid self healing of the capacitor.
