Abstract:
An electronic component may include a substrate having a functional unit formed on a main surface of the substrate and a first resin layer formed on the main surface, the first resin layer having a first surface facing the main surface and a second surface opposed to the first surface, the first resin layer defining a cavity on the first surface enclosing the functional unit, the first resin layer defining a recess on the second surface, and a solder layer being formed in the recess so as not to exceed the second surface in a thickness direction. The functional unit may include a surface acoustic wave (SAW) element or a film bulk acoustic resonator (FBAR) having a mechanically movable portion. The substrate may be formed of dielectric material.
