Abstract
Disclosed is a method for simply fabricating plural surface acoustic wave filter chip packages in large quantities comprising the steps of providing a wafer, on the surface of which plural surface acoustic wave filter chips are formed, and a package substrate, on the surface of which mounting portions corresponding to surface acoustic wave filter chips are formed; providing underfill on the package substrate; mounting the wafer on the package substrate; removing wafer portions between surface acoustic wave filter chips; forming metal shield layers on outer walls of separated surface acoustic wave filter chips; molding a resin on outer walls of surface acoustic wave filter chips coated with metal layers; and dividing the package substrate molded with resin into individual surface acoustic wave filter chip packages.
