Abstract: An electronic component module includes a substrate, an electronic component, an insulating resin, and a shield film. The insulating resin covers a first main surface side of the substrate. The insulating resin exposes an opposite surface of the electronic component. The shield film covers the insulating resin and the opposite surface of the electronic component. The opposite surface has an uneven portion. A concave portion of the uneven portion has a smoother shape than a convex portion of the uneven portion.

Abstract: It is to provide to a module and a method of manufacturing the module in which parasitic capacitance generated between two shield films is reduced without hindering reduction in height of a module. The module includes, a substrate, a component mounted on an upper surface that is one main surface of the substrate, a first shield film provided on an upper surface of the component, sealing resin provided on an upper surface of the substrate so as to seal the component, a second shield film provided on an upper surface or an upper side of the sealing resin, and a low dielectric member arranged between the first shield film and the second shield film and having a dielectric constant lower than a dielectric constant of the sealing resin.

Abstract: An electronic component includes an electronic component main body including a first surface, a signal bump electrode arranged on the first surface to protrude from the first surface of the electronic component main body, and a protective film provided with an opening through which a part of the signal bump electrode is exposed, the protective film being arranged to cover a portion of the signal bump electrode other than a portion exposed through the opening. The protective film includes a first insulating film, a second insulating film that covers the first insulating film, and a first shield film arranged as lying between the first insulating film and the second insulating film. The first shield film is covered with at least one of the first insulating film and the second insulating film so as not to be exposed at an inner surface of the opening.

Abstract: A module includes a substrate, a component mounted on a top surface that is one principal surface of the substrate, a first shielding film provided on a top surface and a side surface of the component, a sealing resin provided on the top surface of the substrate and seals the component, and a second shielding film provided on a top surface of the sealing resin. A hole is provided on a top surface of the sealing resin, to reach at least a part of the first shielding film. The second shielding film disposed in the hole is brought into contact with the first shielding film at positions facing a top surface and a side surface of the component.

Abstract: Heat dissipating characteristics of an acoustic wave filter is improved. A high frequency module includes a mounting substrate, an acoustic wave filter, a resin layer, and a shield layer. The mounting substrate has a first main surface and a second main surface that face each other. The acoustic wave filter is arranged near the first main surface of the mounting substrate. The resin layer is arranged on the first main surface of the mounting substrate and covers an outer peripheral surface of the acoustic wave filter. The shield layer covers the resin layer and the acoustic wave filter. The shield layer is in contact with a second main surface of the acoustic wave filter that is far from the mounting substrate.

Abstract: A radio frequency module includes a mounting substrate, a first electronic component, a second electronic component, a resin layer, and a shield layer. The resin layer covers outer peripheral surfaces of the first electronic component and the second electronic component. The first electronic component includes a first substrate having first and second main surfaces opposed to each other, and a first circuit section formed on the first main surface side of the first substrate. The second electronic component includes a second substrate having first and second main surfaces opposed to each other, and a second circuit section formed on the first main surface side of the second substrate. A material of the first substrate and a material of the second substrate are the same. The shield layer is in contact with the second main surface of the first substrate and the second main surface of the second substrate.

Abstract: An electronic component module includes a substrate, a mounting-type electronic component, a mounting-type electronic component, an insulating resin, and an insulating resin. The mounting-type electronic component is mounted on a first main surface of the substrate. The mounting-type electronic component is mounted on a second main surface of the substrate. The insulating resin covers the first main surface and the first mounting-type electronic component. The insulating resin covers the second main surface and the second mounting-type electronic component. The first mounting-type electronic component is an electronic component including a semiconductor substrate. A top surface of the semiconductor substrate of the first mounting-type electronic component opposite to the first main surface is exposed from the insulating resin. Printing is applied to the top surface, which is an exposed surface of the semiconductor substrate.
