  • Patent number: 8748230
    Abstract: An integrated electromagnetic interference (EMI) shield for a semiconductor module package. The integrated EMI shield includes a plurality of wirebond springs electrically connected between a ground plane in the substrate of the package and a conductive layer printed on the top of the package mold compound. The wirebond springs have a defined shape that causes a spring effect to provide contact electrical connection between the tops of the wirebond springs and the conductive layer. The wirebond springs can be positioned anywhere in the module package, around all or some of the devices included in the package, to create a complete EMI shield around those devices.
    Type: Grant

  • Patent number: 7164192
    Abstract: In one exemplary embodiment, a structure comprises a substrate having a top surface, and a die attach pad situated on the top surface of the substrate. The die attach pad includes a die attach region and at least one substrate ground pad region electrically connected to the die attach region. The die attach pad further includes a die attach stop between the die attach region and the at least one substrate ground pad region. The die attach stop acts to control and limit die attach adhesive flow out to the at least one substrate ground pad region during packaging so that the at least one substrate ground pad region can be moved closer to die attach region so that shorter bond wires for connecting the at least one substrate ground pad region to a die wire bond pad may be used during packaging.
