    摘要: A thin-film device comprises a base electrode made of a metal, a first dielectric layer, a first inner electrode, a second dielectric layer, a second inner electrode, and a third dielectric layer. Letting T1 be the thickness of the lowermost first dielectric layer in contact with the base electrode in the plurality of dielectric layers, and Tmin be the thickness of the thinnest dielectric layer in the plurality of dielectric layers excluding the first dielectric layer, T1>Tmin. Making the first dielectric layer thicker than the thinnest, dielectric layer in the other dielectric layers can increase the distance between a metal part projecting from a metal surface because of the surface roughness of the base electrode and the inner electrode mounted on the lowermost dielectric layer, thereby reducing leakage currents.

    摘要: A thin-film capacitor that is less prone to generation of internal cracking or peeling is provided. In a thin-film capacitor according to the present embodiment, because through holes H are formed in internal electrodes containing Ni as a principal component in a lamination direction, a surface area of at least some of the through holes H is in the range of 0.19 μm2 to 7.0 μm2, and a ratio of a surface area of the through holes H to a surface area of an entire main surface of the internal electrodes is in the range of 0.05% to 5%, peeling or cracking is suppressed from occurring at the boundaries between the internal electrodes and dielectric layers, and as a result, the yield is enhanced.
