Package on package (PoP) devices and methods of packaging semiconductor dies are disclosed. A PoP device includes a first packaged die and a second packaged die coupled to the first packaged die. Metal stud bumps are disposed between the first packaged die and the second packaged die. The metal stud bumps include a bump region and a tail region coupled to the bump region. The metal stud bumps are embedded in solder joints.

Package on package devices and methods of packaging semiconductor dies

A semiconductor wafer is fabricated. The wafer has a plurality of dies. The plurality of dies include at least operable dies of a first type and operable dies of a second type different from the first type. The dies of the second type are rendered inoperable, while keeping the dies of the first type operable. The wafer is provided with the operable dies of the first type and the inoperable dies of the second type on it, for testing of the dies of the first type.
