  • Patent number: 7816775
    Abstract: A method for of manufacturing integrated circuit packages and a multi-chip integrated circuit package are disclosed. According to the method, a first die is attached onto a first side of a set of leads of a leadframe, and an adhesive is applied onto the set of leads at a second side opposite to the first side. A second die is attached onto the adhesive. The adhesive fills into the gaps defined by the set of leads. The adhesive is thereafter cured. In a multi-chip integrated circuit package made according to the method, the adhesive attaching the second die fills the gaps between the leads so that to avoid formation of internal cavities of the package.

  • Patent number: 7723833
    Abstract: A stacked die semiconductor package that includes a substrate with a plurality of adhesive portions arranged in a manner to create at least one gap between the adhesive portions. The package also includes a first semiconductor chip having a non-active surface in contact with the adhesive portions, and an active surface being electrically connected to the substrate. In the package, a second semiconductor chip the non-active surface of the second semiconductor chip is attached to the non-active surface of the first semiconductor chip by a layer of adhesive therebetween. The active surface of the second semiconductor chip is electrically connected to the substrate. An encapsulant material covers the first and second semiconductor chips and their associated electrical connections. The encapsulating material fills the at least one gap between the plurality of adhesive portions and thereby encapsulates the second semiconductor chip and its associated electrical connection.
