An electronic component includes: a substrate; a device chip, in which a functional element is located on a lower surface thereof, that is mounted on an upper surface of the substrate so that the functional element and the upper surface of the substrate are opposite to each other via an air gap; a ring-shaped metal layer that is located on the upper surface of the substrate, surrounds the device chip in a plan view, and has a protruding part located along an outer periphery thereof, an outer side surface of the ring-shaped metal layer being higher than an inner side surface thereof; a metal sealer that surrounds the device chip in the plan view, and is bonded on an upper surface of the ring-shaped metal layer; and a metal film that is located on side surfaces of the metal sealer and the ring-shaped metal layer.

Electronic component and method of manufacturing the same

A method of fabricating an electronic component includes: mounting a device chip on an upper surface of an insulative substrate; forming a sealing portion that seals the device chip; cutting the insulative substrate and the sealing portion; and forming a plated layer covering the sealing portion by barrel plating.

Method of fabricating electronic component

An electronic component module includes: an insulative substrate; a device chip mounted on a first surface of the insulative substrate in flip-chip mounting; a chip component connected to the insulative substrate; a lid provided above the insulative substrate and the device chip; a first metal pattern that is provided in edge portions on the first surface of the insulative substrate so as to surround the first surface of the insulative substrate; a second metal pattern that is provided in edge portions on a second surface of the lid opposite to the first surface so as to surround the second surface; and seal solder joining the first and second metal patterns so as to define a cavity that is formed in a region that is located between the insulative substrate and the lid and is not provided with the first and second metal patterns and is further formed between the insulative substrate and the device chip.

Electronic component module and method for manufacturing the same

An acoustic wave device includes a substrate, a device chip that has a piezoelectric substrate and is flip-chip mounted on a surface of the substrate, a first insulation layer that has a dielectric constant lower than that of the piezoelectric substrate and is provided on a surface of the device chip opposite to another surface that faces the substrate, and a metal seal part that seals the device chip.
