    • A low-profile capacitor that can be bent and that has excellent interlayer adhesion strength. The capacitor includes a dielectric layer, a first capacitor electrode formed on a first main surface of the dielectric layer, a second capacitor electrode formed on a second main surface of the dielectric layer, and a lead electrode formed on the first main surface of the dielectric layer and electrically connected to the second capacitor electrode. The dielectric layer has a thickness of 5 μm or less. The sum of the thicknesses of the first and second capacitor electrodes is 5 μm or more and at least twice the thickness of the dielectric layer. The first and second capacitor electrodes and the lead electrode are formed of a malleable metal. The dielectric layer and the first and second capacitor electrodes are formed by being simultaneously sintered.

    • A dielectric green sheet containing a dielectric ceramic powder, conductor green sheets containing a metal powder, and firing-assisting green sheets containing an inorganic oxide material powder are prepared, and the firing-assisting green sheet, the conductor green sheet, the dielectric green sheet, another conductor green sheet, and another firing-assisting green sheets are stacked in that order to prepare a laminate. The laminate is then fired. During firing, the bonding strength of the interfaces between the conductor green sheets and the firing-assisting green sheets is decreased and the oxygen partial pressure of the firing atmosphere is changed at least once so that the capacitor portion is separated from the firing-assisting green sheets. In this manner, a method for manufacturing thin film capacitor by which a high-reliability thin film capacitor can be produced at high efficiency and low cost without adversely affecting the characteristics of the thin film capacitor.
    • 制备包含电介质陶瓷粉末,含有金属粉末的导体生片和含有无机氧化物材料粉末的焙烧辅助生片的电介质生片,并且,辅助生片,导体生片,电介质生片 ,另一个导体生片,和另一个焙烧辅助生片按顺序堆叠以制备层压体。 然后将层压板烧制。 在焙烧期间,导体生片与助燃原料之间的界面的接合强度降低,并且烧成气氛的氧分压至少改变一次,使得电容器部分与助燃绿 床单。 以这种方式,可以以高效率和低成本生产高可靠性薄膜电容器的薄膜电容器的制造方法,而不会不利地影响薄膜电容器的特性。
