Filed: 2018-11-29
Abstract: To provide a thin film capacitor in which a lower layer dielectric layer is less likely to be damaged via voids, while preventing exfoliation of an electrode layer and the dielectric layer.SOLUTION: A thin film capacitor 1 is formed by laminating electrode layers 12, 14 and dielectric layers 11, 13 alternately. The electrode layer 12 has a first region 12a having double sides covered with the dielectric layers 11, 13, and a second region 12b having one surface exposed from the dielectric layer 13, and the other surface covered with the dielectric layer 11. Formation density of voids V contained in the second region 12b is lower than the formation density of voids V contained in the first region 12a. With such an arrangement, adhesion of the electrode layer and the dielectric layer is increased, because stress is released in the first region 12a, and the lower layer dielectric layer is less likely to be damaged via the voids in the second region 12b. With such an arrangement, reliability of the thin film capacitor can be increased.SELECTED DRAWING: Figure 2
