Each substrate has similar length and width to the predetermined length and width of the semiconductor package. A carrier having a plurality of openings is prepared. Each opening is larger in length and width than the substrate. The substrates are positioned in the corresponding openings, and gaps between the substrates and the carrier are sealed. A molding process is performed to form an encapsulant over each opening to encapsulate the chip. An area on the carrier covered by the encapsulant is larger in length and width than the opening. After performing a mold-releasing process, a plurality of the semiconductor packages are formed by a singulation process to cut along substantially edges of each substrate according to the predetermined size of the semiconductor package.

    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.
