  • Patent number: 7473993
    Abstract: A semiconductor stack package includes lower and upper individual packages. When the upper individual package is stacked on the lower individual package, a heat-conducting layer provided under the upper package touches a heat-mediating layer provided on the lower package. Thus, a layer of trapped air found in conventional stack packages is eliminated, and a direct heat-dissipating path is produced through both the heat-conducting layer and the heat-mediating layer. Therefore, the heat dissipation of the stack package is improved. Alternatively, the stack package may have a symmetric configuration in which each IC chip faces away from each other. A memory module has several stack packages mounted on one or both surfaces of a module board. The method includes forming the packages and stacking the packages. The method further includes forming a module board and mounting the stack packages on the module board.

  • Publication number: 20070126114
    Abstract: In one embodiment, a heat-dissipating member includes a heat-dissipating body, a heat-transferring body and an attaching member. The heat-dissipating body externally dissipates heat originating in a heat source. The heat-transferring member is interposable between the heat-dissipating body and the heat source. The attaching member is placed on a surface of the heat-dissipating body and corresponds to the heat-transferring body so as to couple the heat-transferring member to the heat-dissipating body. Thus, heat generated from the heat source, such as a semiconductor element, rapidly dissipates through the heat-transferring member and externally through the heat-dissipating body.
