摘要： A capacitor may comprise a substrate and a first electrically conductive electrode layer. A metal oxide layer may be deposited on at least one of the substrate or the first electrically conductive electrode layer. A proximal region of the metal oxide may comprise a stoichiometric, dielectric, oxygen vacancy-free portion of the metal oxide. The proximal region may be in communication with the first electrically conductive electrode layer. A distal region of the metal oxide may comprise a constant oxygen vacancy portion. The distal region may be in communication with a second electrically conductive electrode layer. The metal oxide may comprise a gradient region comprising a substantially stoichiometric metal oxide portion and a substantially constant oxygen vacancy portion. The gradient region may comprise an increasing oxygen vacancy gradient from the proximal region to the distal region. The second electrically conductive electrode layer may be deposited on the distal region.

摘要： To provide a thin film capacitor having high adhesion performance 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. The first and second electrode layers are formed in an area surrounded by an outer peripheral area of the upper surface of the metal foil so as not to cover the outer peripheral area. The outer peripheral area of the roughened upper surface of the metal foil is thus exposed, so that adhesion performance with respect to a circuit substrate can be enhanced.

摘要： An interdigitated metal-insulator-metal capacitor structure is formed by a first unitary body of a first conductive material that includes a first metal plate, a first set of interdigitated electrodes protruding upwards from a top surface of the first metal plate, and a first set of connecting vias protruding downwards from a bottom surface of the first metal plate. A second unitary body of a second conductive material is disposed above the first unitary body and electrically separated from the first unitary body by an insulating layer. The second unitary body includes a second metal plate, a second set of interdigitated electrodes protruding downwards from a bottom surface of the second metal plate, and a second set of connecting vias protruding upwards from a top surface of the second metal plate. The first set of interdigitated electrodes are interleaved with the second set of interdigitated electrodes.

摘要： A dielectric film includes a main component of a complex oxide represented by a general formula of (Sr1-xCax)yTiO3. 0.40≤x≤0.90 and 0.90≤y≤1.10 are satisfied. A ratio of a diffraction peak intensity on (1, 1, 2) plane of the complex oxide to a diffraction peak intensity on (0, 0, 4) plane of the complex oxide in an X-ray diffraction chart of the dielectric film is 3.00 or more. Instead, a ratio of an intensity of a diffraction peak appearing at a diffraction angle 2θ of 32° or more and 34° or less to an intensity of a diffraction peak appearing at a diffraction angle 2θ of 46° or more and 48° or less in an X-ray diffraction chart of the dielectric film obtained by an X-ray diffraction measurement with Cu-Kα ray as an X-ray source is 3.00 or more.

摘要： An integrated energy storage component that includes a substrate supporting a contoured layer having a region with a contoured surface such as elongated pores. A stack structure is provided conformally over the contoured surface of this region. The stack is a single or repeated instance of MOIM layers, or MIOM layers, the M layers being metal layers, or a quasi-metal such as TiN, the O layers being oxide layers containing ions, and the I layer being an ionic dielectric. The regions having a contoured surface may be formed of porous anodized alumina.
