    摘要: A method for fabricating semiconductor packages is disclosed, including mounting and electrically connecting a semiconductor chip onto a chip carrier; mounting a heat-dissipating structure on the semiconductor chip; placing the heat-dissipating structure into a mold cavity for filling therein a packaging material to form an encapsulant, wherein the heat-dissipating structure has a heat spreader having a size larger than that of the predetermined size of the semiconductor package, a covering layer formed on the, and a plurality of protrusions formed on edges of the covering layer that are free from being corresponding in position to the semiconductor chip, such that the protrusions can abut against a top surface of the mold cavity to prevent the heat spreader from being warped; and finally performing a singulation process according to the predetermined size and removing the encapsulant formed on the covering layer to form the desired semiconductor package. Also, this invention discloses a heat-dissipating structure applicable to the method described above.

    摘要: A heat dissipation semiconductor package includes a chip carrier, a semiconductor chip, a heat conductive adhesive, a heat dissipation member, and an encapsulant. The semiconductor chip is flip-chip mounted on the chip carrier and defined with a heat conductive adhesive mounting area. Periphery of the heat adhesive mounting area is spaced apart from edge of the semiconductor chip. The heat dissipation member is mounted on the heat conductive adhesive formed in the heat conductive adhesive mounting area. The encapsulant formed between the chip carrier and the heat dissipation member encapsulates the semiconductor chip and the heat conductive adhesive, and embeds edges of the active surface and non-active surface and side edge of the semiconductor chip, thereby increasing bonding area between the encapsulant and the semiconductor chip. The side edges of the heat conductive adhesive and the semiconductor chip are not flush with each other, thereby preventing propagation of delamination.
