    摘要: A stack structure of semiconductor packages and a method for fabricating the stack structure are provided. A plurality of electrical connection pads and dummy pads are formed on a surface of a substrate of an upper semiconductor package and at positions corresponding to those around an encapsulant of a lower semiconductor package. Solder balls are implanted to the electrical connection pads and the dummy pads. The upper semiconductor package is mounted on the lower semiconductor package. The upper semiconductor package is electrically connected to the lower semiconductor package by the solder balls implanted to the electrical connection pads, and the encapsulant of the lower semiconductor package is surrounded and confined by the solder balls implanted to the dummy pads. Thereby, the upper semiconductor package is properly and securely positioned on the lower semiconductor package, without the occurrence of misalignment between the upper and lower semiconductor packages.

    摘要: A semiconductor package with a heat dissipating device and a fabrication method of the semiconductor package are provided. A chip is mounted on a substrate. The heat dissipating device is mounted on the chip, and includes an accommodating room, and a first opening and a second opening that communicate with the accommodating room. An encapsulant is formed between the heat dissipating device and the substrate to encapsulate the chip. A cutting process is performed to remove a non-electrical part of structure and expose the first and second openings from the encapsulant. A cooling fluid is received in the accommodating room to absorb and dissipate heat produced by the chip. The heat dissipating device covers the encapsulant and the chip to provide a maximum heat transfer area for the semiconductor package.

    摘要: A semiconductor package with a heat sink is provided. At least one chip and a heat sink attached to the chip are mounted on a substrate. At least one slot is formed through at least one corner of the heat sink at a position attached to the substrate. An adhesive material is applied between the heat sink and substrate and over filled in the slot with an overflow of the adhesive material out of the slot. The adhesive material over filled in the slot provides an anchoring effect and increases its contact area with the heat sink to thereby firmly secure the heat sink on the substrate. Further, the slot formed at the corner of the heat sink can alleviate thermal stresses accumulated at the corner of the heat sink and thereby prevent delamination between the heat sink and the substrate.

    摘要: A chip carrier for a semiconductor chip is provided. A plurality of solder pads for bump soldering are formed on a chip mounting surface of the chip carrier, to allow a flip chip to be mounted and electrically connected to the chip carrier. A solder mask layer is formed on the chip carrier, wherein a plurality of openings are provided in the solder mask layer to expose the solder pads, and an outwardly opening extended portion is formed respectively from the openings corresponding to the solder pads having a relatively narrower pitch therebetween, so as to prevent formation of voids during an underfill process for filing a gap between the flip chip and the chip carrier.
