    摘要: A semiconductor package with a heat sink and a method for fabricating the same are proposed. A first adhesive of a low Young's modulus is disposed on a corner region of a heat sink mounting area of a substrate. A second adhesive of a high Young's modulus is disposed on the heat sink mounting area except the corner region. The heat sink is mounted on the heat sink mounting area and thereby secured in position to the substrate, by the first and second adhesives. The disposition of the first and second adhesives of different Young's moduli not only prevents detachment of the heat sink from the substrate, but also controls the flatness of the heat sink. The prevent invention does not affect the appearance of the semiconductor package and its ensuing assembly process.

    摘要: A flip-ship semiconductor package with a lead frame as a chip carrier is provided, wherein a plurality of leads of the lead frame are each formed with at least a dam member thereon. When a chip is mounted on the lead frame by means of solder bumps, each of the solder bumps is attached to the corresponding one of the leads at a position between the dam member and an inner end of the lead. During a reflow-soldering process for wetting the solder bumps to the leads, the dam members would help control collapse height of the solder bumps, so as to enhance resistance of the solder bumps to thermal stress generated by CTE (coefficient of thermal expansion) mismatch between the chip and the leads, thereby preventing incomplete electrical connection between the chip and the leads.
