  • Publication number: 20080061451
    Abstract: A semiconductor package and a fabrication method thereof are disclosed. The fabrication method includes the steps of providing a semiconductor chip having an active surface and a non-active surface opposing to the active surface, roughening a peripheral portion of the non-active surface so as to divide the non-active surface into the peripheral portion formed with a roughened structure and a non-roughened central portion, mounting the semiconductor chip on a chip carrier via a plurality of solder bumps formed on the active surface, forming an encapsulant on the chip carrier to encapsulate the semiconductor chip. The roughened structure formed on the peripheral portion of the non-active surface of the semiconductor chip can reinforce the bonding between the semiconductor chip and the encapsulant, and the non-roughened central portion of the non-active surface of the semiconductor chip can maintain the structural strength of the semiconductor chip.

  • Publication number: 20080017977
    Abstract: 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.

  • Publication number: 20080006933
    Abstract: The invention provides a heat-dissipating package structure and a fabrication method thereof. The fabrication method includes the steps of mounting and electrically connecting a semiconductor chip to a chip carrier; mounting on the semiconductor chip a heat-dissipating member having an interface layer; performing a molding process to form an encapsulant that encapsulates the semiconductor chip and the heat-dissipating member; cutting the chip carrier and the encapsulant according to a predetermined package size and forming an oblique angle on a top edge of the encapsulant to partially expose an edge of the heat-dissipating member; and removing the encapsulant located on the interface layer. During the molding process, the formed encapsulant can cover the interface layer due to a spacing height exists between the interface layer and the top wall of the mold cavity, thereby preventing damages to the semiconductor chip pressed by the mold and the problem of flash.
