Patent ID: 6852561

Claim:
A method for collective fabrication of surface acoustic wave components, comprising: making surface acoustic wave devices on a piezoelectric substrate; making first internal conductive contacts on a surface of said surface acoustic wave devices; making a first hollowed layer on all of the surface acoustic wave devices such that said first internal conductive contacts are completely covered by said first hollowed layer; bonding a printed circuit to said first hollowed layer to form cavities between said printed circuit and said substrate in hollows of said first hollowed layer; making via holes in the printed circuit and the first hollowed layer up to the first internal conductive contacts of the surface acoustic wave devices; metallizing the via holes and defining second external conductive contacts such that said second external conductive contacts are connected to said first internal conductive contacts by the metallized via holes; and cutting out an assembly formed by the substrate, at least a pair of said first internal conductive contacts, the first hollowed layer, at least a pair of said second external conductive contacts, and the printed circuit so as to separate the surface acoustic wave components.
