  • Publication number: 20180114781
    Abstract: A package structure and a manufacturing method thereof are provided. The package structure includes a circuit carrier, a substrate, a die, a plurality of conductive wires and an encapsulant. The substrate is disposed on the circuit carrier and includes a plurality of openings. The die is disposed between the circuit carrier and the substrate. The conductive wires go through the openings of the substrate to electrically connect between the substrate and the circuit carrier. The encapsulant is disposed on the circuit carrier and encapsulates the die, the substrate and the conductive wires.

  • Publication number: 20180114736
    Abstract: A chip package structure includes a substrate, a chip, an encapsulant, a plurality of solder balls and a patterned metal layer. The substrate includes a first surface and a second surface opposite to each other. The chip is disposed on the first surface and electrically connected to the substrate. The encapsulant encapsulates the chip and covering the first surface. The solder balls are disposed on the second surface and electrically connected to the substrate. The patterned metal layer s disposed on the encapsulant. The patterned metal layer includes at least one concave portion and at least one convex portion defined by the concave portion. The convex portion faces the encapsulant. The adhesion layer is disposed between the patterned metal layer and the encapsulant. The adhesion layer is filled in the concave portion.

  • Publication number: 20180114704
    Abstract: A manufacturing method of a POP structure including at least the following steps is provided. A first package structure is formed and a second package structure is formed on the first package structure. The first package structure includes a circuit carrier and a die disposed on the circuit carrier. Forming the first package structure includes providing a conductive interposer on the circuit carrier, encapsulating the conductive interposer by an encapsulant and removing a portion of the encapsulant and the plate of the conductive interposer. The conductive interposer includes a plate, a plurality of conductive pillars and a conductive protrusion respectively extending from the plate to the circuit carrier and the die. The conductive protrusion disposed on the die, and the conductive pillars are electrically connected to the circuit carrier. The second package structure is electrically connected to the first package structure through the conductive interposer.

  • Publication number: 20170358557
    Abstract: A POP structure includes a first package structure, an interposer, and a second package structure. The first package structure includes a first carrier, a first chip, conductive structures, and a first insulation encapsulation. The first carrier has a first surface and a second surface opposite to the first surface. The first chip and the conductive structures are disposed on the first surface of the first carrier. The first insulation encapsulation is formed on the first surface of the first carrier and encapsulates the conductive structures and the first chip. Top surfaces of the conductive structures are exposed through the first insulation encapsulation and are coplanar. The interposer is disposed on and electrically connected to the first package structure. The second package structure is disposed on and electrically connected to the interposer. A manufacturing method of a POP structure is also provided.
