    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 photosensitive semiconductor package with a support member and its fabrication method are provided. The support member having a receiving space is placed on an upper surface of a substrate. An encapsulation body is formed on the substrate and bonded with an outer wall of the support member. At least one chip is mounted on a predetermined area of the substrate exposed via the receiving space, and is electrically connected to the substrate. A light-permeable lid is attached to the support member and the encapsulation body to seal the receiving space. A plurality of solder balls or contact lands are formed on a lower surface of the substrate. By provision of the support member, there is no need to use an insert mold, such that the substrate would not be damaged by the insert mold, and bond fingers on the substrate would not be contaminated by the insert mold.

    摘要: A semiconductor package includes a substrate having a top surface and a bottom surface; at least one chip mounted on the top surface of the substrate and electrically connected to the substrate; a heat sink attached to the top surface of the substrate by an adhesive material applied therebetween; and a plurality of solder balls implanted on the bottom surface of the substrate. The heat sink has a flat portion and a support portion connected to the flat portion. The support portion has at least one recess portion facing toward the top surface of the substrate and at least one burr formed on an interior surface of the recess portion such that the adhesive material can fill the recess portion and submerge the burr to provide an anchoring effect to firmly secure the heat sink in position on the substrate.
