Abstract
A dielectric composed of a core material between two polymer layers that have permittivity values less than the core material. The polymer layers provide structural integrity for the dielectric. The dielectric can be employed in a capacitor to fine tune the capacitance of the capacitor. The dielectric and the capacitor may have a thickness in the micron range. Accordingly, the dielectric and capacitor provide for the miniaturization of electronic devices. The dielectric may be employed in decoupling capacitors to reduce noise in electronic devices.
Claims23
A dielectric laminate comprising a core layer bonded to a first polymer layer and to a second polymer layer, the core layer has a permittivity higher than the first polymer layer and the second polymer layer, the first and second polymer layers provide a means such that the dielectric laminate is self-supporting.
A method for forming a self-supporting dielectric comprising:
- depositing on a first polymer layer a core dielectric material;
- and depositing a second polymer layer on a surface of the core dielectric opposite the first polymer layer to form the self-supporting dielectric, the core has a permittivity higher than the first and the second polymer layers.
