    Abstract: Prismatic polymer monolithic capacitor structure that includes multiple interleaving radiation-cured polymer dielectric layers and metal layers. Method for fabrication of same. The chemical composition of polymer dielectric and the electrode resistivity parameters are chosen to maximize the capacitor self-healing properties and energy density, and to assure the stability of the capacitance and dissipation factor over the operating temperature range. The termination electrode that extends beyond the active capacitor area and beyond the polymer dielectric layers has a thickness larger than that used industrially to provide resistance to thermomechanical stress. The glass transition temperature of the polymer dielectric is specifically chosen to avoid mechanical relaxation from occurring in the operating temperature range, which prevents high moisture permeation (otherwise increasing a dissipation factor and electrode corrosion) into the structure.

  • Patent number: 11728090
    Abstract: Micro-scale devices, such as transformers and capacitors, having a floating conductive layer are disclosed. A floating conductive layer may be disposed in an insulator layer and can reduce a maximum electric field between a first planar conductor and a second planar conductor of a micro-scale passive device. Reduction of a maximum electric field between a first planar conductor and a second planar conductor can reduce undesirable effects on electrical components.
