Thin-film capacitor with protective insulating films embedding capacitor electrodes

A thin film capacitor including first and second unit capacitors,

• wherein each of the first and second unit capacitors comprises:
• a dielectric layer having a first surface and a second surface positioned on an opposite side of the first surface;
• a first capacitor electrode formed on the first surface of the dielectric layer;
• a second capacitor electrode formed on the second surface of the dielectric layer;
• a first protective insulating film formed on the first surface of the dielectric layer so as to embed therein the first capacitor electrode;
• a second protective insulating film formed on the second surface of the dielectric layer so as to embed therein the second capacitor electrode;
• a first terminal electrode electrically connected to the first capacitor electrode;
• and
• a second terminal electrode electrically connected to the second capacitor electrode,
• wherein the first terminal electrode has a first section positioned on an upper surface of the first protective insulating film and partly overlapping the second capacitor electrode and a second section positioned on a side surface of the first protective insulating film so as to contact the first capacitor electrode,
• wherein the second terminal electrode is not formed on the upper surface of the first protective insulating film, and
• wherein the first and second unit capacitors are stacked such that (1) the first section of the first terminal electrode included in the first unit capacitor and the first section of the first terminal electrode included in the second unit capacitor are connected to each other;
• and (2) a surface of the first protective insulating film opposite the dielectric layer in the first unit capacitor and a surface of the first protective insulating film opposite the dielectric layer in the second unit capacitor face each other.
