    摘要: Disclosed herein is a polymer-ceramic dielectric composition. The dielectric composition comprises a polymer and a ceramic dispersed in the polymer wherein the ceramic is composed of a material having a perovskite structure represented by ABO3 and a metal oxide dopant and has an electrically charged surface. According to the dielectric composition, the surface of the ceramic is electrically charged to induce space-charge polarization (or interfacial polarization) at the polymer/ceramic interface, resulting in an increase in dielectric constant. Since the dielectric composition has a high dielectric constant particularly in a low-frequency range, it can be suitably used to produce decoupling capacitors. Further disclosed are a capacitor and a printed circuit board that use the dielectric composition.

The composite dielectric composition of the present invention can be used in preparation of the signal-matching embedded capacitor due to a small variation of capacitance with temperature.

    摘要: A method of manufacturing a thin film capacitor includes steps of: performing recrystallization heat treatment on a metal foil; forming a dielectric layer on a top surface of the recrystallized metal foil; heat treating the metal foil and the dielectric layer; and forming an upper electrode on a top surface of the heat-treated dielectric layer. The recrystallization heat treatment prevents the oxidation of a metal foil, by which a dielectric layer can be heat treated at a high temperature, thereby improving electric properties of a thin film capacitor and the reliability of a product.
