Abstract:
A stacked package has plurality of chip packages stacked on a base. Each chip package has an exterior conductive element formed on the active surface. Each exterior conductive element has a cut edge exposed on a lateral side of the chip package. The lateral trace is formed through the encapsulant and electrically connects to the cut edges of the chip packages. The base has an interconnect structure to form the electrical connection between the lateral trace and the external terminals. Therefore, the process for forming the electrical connections is simplified to enhance the reliability and the UPH for manufacturing the stacked package.

Claim (Index 1):
A stacked package comprising:\n a plurality of chip packages stacked on each other, each of the plurality of chip packages comprises:\n a chip having an active surface and a back surface opposite to the active surface; \n a passivation layer formed on the active surface of the chip; and \n a plurality of exterior conductive elements formed on the active surface of the chip and electrically connected to the chip, and each exterior conductive element having a cut edge exposed on a lateral side of the chip package; \n a plurality of adhesives attached respectively between adjacent chip packages; a first encapsulant encapsulating the chip packages and having a through hole formed along the cut edges of the chip packages; a lateral trace formed in the through hole of the first encapsulant to electrically connect the cut edges of the chip packages; and a base attached to a bottom chip package of the plurality of chip packages and a bottom of the first encapsulant and having an interconnect structure electrically connecting to the lateral trace.
