Title:
MULTILAYER FILM INCLUDING FIRST AND SECOND DIELECTRIC LAYERS
Document Type and Number:
WIPO Patent Application WO/2014/081917
Kind Code:
A3
Abstract:
A multilayer dielectric film including a first dielectric layer made from a material having a first breakdown field strength and a second dielectric layer disposed on the first dielectric layer made from a material having a different breakdown filed strength. A multilayer film including a first electrically conductive layer, the first dielectric layer disposed on the first electrically conductive layer, the second dielectric layer disposed on the first dielectric layer, and a second electrically conductive layer disposed on the second dielectric layer is also disclosed. The first electrically conductive layer can have at least one of an average surface roughness of at least ten nanometers, a thickness of at least ten micrometers, or an average visible light transmission of up to ten percent. The first dielectric layer may be a polymer and typically has a lower dielectric constant than the second dielectric layer, which may be ceramic.
