    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.

    摘要: This invention provides a method for fabricating a semiconductor device and a carrier applied therein. The method includes the steps of: disposing a chip-mounted substrate in an opening of a carrier; forming at least a storage aperture and at least an inspection aperture in the carrier; infusing an adhesive into the storage aperture to fill a gap between the substrate and carrier with the adhesive by capillarity; determining whether the inspection aperture is filled with the adhesive to ascertain whether the gap is completely filled with the adhesive; in response to a positive result, performing a molding process to form a molding compound for encapsulating the chip; and performing implantation of solder ball and a singulation process to form a semiconductor device with desirable dimensions. The inspection aperture is inspected with a naked eye to determine whether the gap is completely filled with the adhesive, thereby reducing inspection costs and increasing yields of products with no additional packaging costs.

    摘要: A heat dissipating semiconductor package and a heat dissipating structure thereof are provided. The heat dissipating structure includes an outer surface, consecutive recessed step portions, and a pressure-releasing groove. The outer surface is exposed from an encapsulant made of a molding compound. The step portions are formed at an edge of the outer surface and have decreasing depths wherein the closer a step portion to a central position of the outer surface, the smaller the depth of this step portion is. The pressure-releasing groove is disposed next to and deeper than the innermost one of the step portions. A molding compound flows to the step portions and absorbs heat from an encapsulation mold quickly, such that a flowing speed of the molding compound is reduced. Pressure suffered by air remaining at the step portions is released through the pressure-releasing groove, thereby preventing flashes of the molding compound and resin bleeding.

    摘要: A method for fabricating semiconductor packages is proposed. A plurality of substrates each having a chip thereon are prepared. 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. A waste of substrate material is avoided.
