Abstract: To provide a thin film capacitor having high adhesion with respect to a circuit substrate. A thin film capacitor includes: a metal foil having a roughened upper surface; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the dielectric film without contacting the metal foil. An angle ?a formed by the other main surface of the metal foil and a side surface thereof is more than 20° and less than 80°. The side surface is thus tapered at an angle of more than 20° and less than 80°, so that it is possible to suppress warpage and to enhance adhesion with respect to a multilayer substrate when the thin film capacitor is embedded in the multilayer substrate.

Abstract: To provide a thin film capacitor in which warpage is less likely to occur. A thin film capacitor includes: a metal foil having roughened upper and lower surfaces; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a dielectric film covering the lower surface of the metal foil and made of a dielectric material having a thermal expansion coefficient smaller than that of the metal foil; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the first dielectric film without contacting the metal foil. The lower surface of the metal foil is thus covered with the dielectric film having a small thermal expansion coefficient, thereby making it possible to prevent the occurrence of warpage.
