A method of making a semiconductor device, includes: providing a first dielectric layer; sequentially forming a first metal layer, a dummy capacitor dielectric layer, and a second metal layer over the first dielectric layer; and using a single mask layer with two patterns to simultaneously recess two portions of the second metal layer so as to define a metal thin film of a resistor and a top metal plate of a capacitor.

To provide a thin film capacitor in which peeling-off of an electrode layer is less likely to occur. 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 for partly exposing the metal foil therethrough, a first electrode layer contacting the metal foil through the opening and further contacting the dielectric film, and a second electrode layer contacting the dielectric film without contacting the metal foil. With this configuration, both the first and second electrode layers can be disposed on the upper surface of the metal foil. In addition, the first electrode layer contacts not only the metal foil but also the dielectric film, making peeling of the first electrode layer less likely to occur.

The TFC can be positioned in or on a layer of the package substrate close to a component (e.g., a die, a die stack, etc.) on the package substrate that may require a decoupling capacitance.

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. An angle θa formed by the other main surface of the metal foil and a side surface thereof is more than 20° and less than 80°. The side surface is thus tapered at an angle of more than 20° and less than 80°, so that it is possible to suppress warpage and to enhance adhesion with respect to a multilayer substrate when the thin film capacitor is embedded in the multilayer substrate.
