    Abstract: 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.

    Abstract: A package structure includes a first redistribution layer, a second redistribution layer, a die, a plurality of conductive pillars and a die-stacked structure. The first redistribution layer has a first surface and a second surface opposite to the first surface. The second redistribution layer is disposed above the first surface. The die is disposed between the first redistribution layer and the second redistribution layer and has an active surface and a rear surface opposite to the active surface. The active surface is adhered to the first surface, and the die is electrically connected to the first redistribution layer. The conductive pillars are disposed and electrically connected between the first redistribution layer and the second redistribution layer. The die-stacked structure is bonded on the second redistribution layer.

    Abstract: A manufacturing method of a package structure is described. The method includes at least the following steps. A carrier is provided. A semiconductor die and a sacrificial structure are disposed on the carrier. The semiconductor die is electrically connected to the bonding pads on the sacrificial structure through a plurality of conductive wires. As encapsulant is formed on the carrier to encapsulate the semiconductor die, the sacrificial structure and the conductive wires. The carrier is debonded, and at least a portion of the sacrificial structure is removed through a thinning process. A redistribution layer is formed on the semiconductor die and the encapsulant. The redistribution layer is electrically connected to the semiconductor die through the conductive wires.
