Technical Examples

A method for making a SAW device package includes the steps of: forming a pattern of a metal layer, that defines transmitting and receiving transducers of a SAW die, on a wafer; forming a pattern of a first photo sensitive layer, which defines a peripheral wall of a cap of the SAW die, on the metal layer and the wafer through lithography techniques; forming a pattern of a second photo sensitive layer, which defines a cover wall of the cap of the SAW die, on the first photo sensitive layer through lithography techniques; curing the first and second photo sensitive layers; dicing the wafer into SAW dies; and encapsulating the SAW dies with a molding compound.
