    Abstract: A semiconductor package with stacked chips is proposed, wherein at least two chips are stacked on a chip carrier in a stagger manner as to dispose a second chip on a first chip, and a supporting element is disposed on the second chip and dimensioned to cover area on the second chip with no support from the first chip. The supporting element provides support to the second chip, allowing bonding wires to be successfully connected to the second chip, without the occurrence of cracks of the second chip. The supporting element can be formed on its lower surface with protruding portions positioned outside edge sides of the second chip; this is to enhance structural strength of the supporting element, and help maintain the second chip intact in structure during wire bonding. The supporting element can further have its upper surface to be exposed to the atmosphere; this improves heat dissipating efficiency of the semiconductor package.

    Abstract: A multi-chip stack structure and a fabrication method thereof are proposed, including providing a leadframe having a die base and a plurality of leads and disposing a first and a second chips on the two surfaces of the die base respectively; disposing the leadframe on a heating block having a cavity in a wire bonding process with the second chip received in the cavity of the heating block; performing a first wire bonding process to electrically connect the first chip to the leads through a plurality of first bonding wires, and forming a bump on one side of the leads connected with the first bonding wires; disposing the leadframe in an upside down manner to the heating block via the bump with the first chip and the first bonding wires received in the cavity of the heating block; and performing a second wire bonding process to electrically connect the second chip to the leads through a plurality of second bonding wires. The bump is used for supporting the leads to a certain height so as to keep the bonding wires from contacting the heating block and eliminate the need of using a second heating block in the second wire bonding process of the prior art, thereby saving time and costs in a fabrication process. Also, as positions where the first and second bonding wires are bonded to the leads on opposite sides of the leadframe correspond with each other, the conventional problems of adversely affected electrical performance and electrical mismatch can be prevented.

    Abstract: 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.
