Capacitor substrate structure
The disclosed is a capacitor substrate structure to reduce the high leakage current and low insulation resistance issue of organic/inorganic hybrid materials with ultra-high dielectric constant. The insulation layer, disposed between two conductive layers, includes multi-layered dielectric layers. At least one of the dielectric layers has high dielectric constant, including high dielectric constant ceramic powder and conductive powder evenly dispersed in organic resin. The other dielectric layers can be organic resin, or further include high dielectric constant ceramic powder dispersed in the organic resin. The substrate has an insulation resistance of about 50KΩ and leakage current of below 100 μAmp under operational voltage.
