  • Publication number: 20230253446
    Abstract: To provide a thin film capacitor having high adhesion performance with respect to a multilayer 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. A height of the first electrode layer is lower than a height of the second electrode layer. This enhances adhesion performance when the thin film capacitor is embedded in a multilayer substrate and improves ESR characteristics.

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.

  • Publication number: 20230138154
    Abstract: An electronic component includes conductor layers and insulating resin layers which are alternately stacked on a substrate. One of the insulating resin layers positioned in the lowermost layer is smaller in thickness than the insulating resin layers, and the insulating resin layers are smaller in thermal expansion coefficient than the one of the insulating resin layers. Thus, an element that requires high processing accuracy, such as a capacitor, can be embedded in the insulating resin layer positioned in the lowermost layer and having a small thickness, and an element that requires a sufficient conductor thickness, such as an inductor, can be embedded in the insulating resin layers having a large thickness. In addition, since the insulating resin layers each have a small thermal expansion coefficient, the occurrence of warpage and peeling can be suppressed.

  • Publication number: 20230005667
    Abstract: An electronic component includes: a conductive pattern provided on the main surface of a substrate and constituting a lower electrode; a dielectric film that covers top and side surfaces of the conductive pattern; and a conductive pattern stacked on the top surface of the conductive pattern through the dielectric film and constituting an upper electrode. A part of the dielectric film that is parallel to the main surface of the substrate is removed at least partly. Partially removing a part of the dielectric film that is parallel to the main surface of the substrate allows stress relaxation. This prevents peeling at the interface between the lower electrode and the dielectric film.
