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 17):
A manufacturing method of a stacked package comprising steps of:\n providing a plurality of chip packages, wherein 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 packages; \n stacking the chip packages on a carrier, wherein the back surface of one chip package faces the active surface of the adjacent chip package, a plurality of adhesives are attached respectively between adjacent chip packages and the carrier attached to a bottom chip package of the plurality of chip packages; encapsulating the chip packages on the carrier by a first encapsulant; forming a through hole through the first encapsulant to expose the cut edges of the chip packages; forming a lateral trace in the through hole to electrically connect the cut edges of the chip packages; detaching the carrier to expose an end of the lateral trace; forming a redistribution layer to electrically connect to the end of the lateral trace; and performing singulation to form a stacked package.
