Abstract: A semiconductor package assembly including a molded leadless package (MLP) having an exposed top emitter pad and an exposed bottom source pad. A folded heat sink is attached to the exposed top emitter pad of the MLP by a soft solder attach process. The folded heat sink has a planar member generally coextensive in size with the MLP and in electrical and thermal contact with the top emitter pad of the MLP, and also has one or more leads extending generally perpendicularly to the planar member in a direction towards the lower surface of the MLP. These heat sink leads may provide the emitter connection to a printed circuit (PC) board.

Abstract: This application relates to semiconductor packages comprising stacked die assemblies. In some cases, the stacked dies comprise a first die containing gate driver IC that is stacked on a first surface of a second IC die. A second surface of the second IC die can be bumped for connection to one or more bump attach pads. The first die can be wire bonded to one or more bond attach pads. In some instances, the semiconductor packages include a leadframe clip that connects with the drain on the first die. In such instances, the gate driver IC of the first die can be stacked on a first surface of the leadframe clip and a second surface of the leadframe clip can be stacked on the first surface of the second IC die. The semiconductor packages can be molded and/or configured into a ball grid array (“BGA”) or a land grid array (“LGA”) configuration. Other embodiments are described.
