    摘要: A semiconductor package including a stacked-die structure, a second encapsulant laterally encapsulating the stacked-die structure and a redistribution layer disposed on the second encapsulant and the staked-die structure is provided. The stacked-die structure includes a first semiconductor die including a first active surface, a circuit layer disposed on the first active surface, a second semiconductor die including a second active surface facing towards the first active surface, a plurality of conductive features distributed at the circuit layer and electrically connected to the first and second semiconductor die and a first encapsulant encapsulating the second semiconductor die and the conductive features. A portion of the conductive features surrounds the second semiconductor die. The redistribution layer is electrically connected to the staked-die structure. A manufacturing method of a semiconductor package is also provided.

    摘要: A package structure including a redistribution structure, a die, at least one connecting module, a first insulating encapsulant, a chip stack, and a second insulating encapsulant. The die is disposed on and electrically connected to the redistribution structure. The connecting module is disposed on the redistribution structure. The connecting module has a protection layer and a plurality of conductive bars. The conductive bars are embedded in the protection layer. The protection layer includes a plurality of openings corresponding to the conductive bars. The first insulating encapsulant encapsulates the die and the connecting module. The chip stack is disposed on the first insulating encapsulant and the die. The chip stack is electrically connected to the connecting module. The second insulating encapsulant encapsulates the chip stack.

    摘要: A conductive layer is formed on a first surface of a first carrier. The redistribution layer is formed on the conductive layer. Then an open-test is performed to the redistribution layer. Since the conductive layer and the redistribution layer constitute a closed loop, a load should be presented during the open-test if the redistribution layer is formed correctly. After the open-test is performed, the first carrier and the conductive layer are removed. Then a short-test is performed to the redistribution layer. No load is presented during the short-test if the redistribution layer is formed correctly since the redistribution layer constitutes an open loop. Therefore, whether the redistribution layer has flaws can be determined before the dies are boned on the redistribution layer. Thus, no waste of the good die occurs because of the flawed redistribution layer.

    摘要: A testing device includes a transfer interface, a tester, a first socket group and a second socket group. The first socket group includes a plurality of tested devices coupled in series and the second socket group includes a plurality of tested devices coupled in series. The tester is electrically connected to the socket group via the transfer interface. The transfer interface is configured to merge a first testing signal with a second testing signal to generate a double frequency testing signal. The double-frequency testing signal and a plurality of control signals are provided to the tested devices in the first socket group and the second socket group to perform the testing procedure on the tested devices of a same tested device pair simultaneously, and performing the testing procedure on the tested device pairs sequentially.
