  • Patent number: 9218987
    Abstract: A top-side cooled semiconductor package with stacked interconnection plate is disclosed. The semiconductor package includes a circuit substrate with terminal leads, a semiconductor die atop the circuit substrate, a low thermal resistance intimate interconnection plate for bonding and interconnecting a top contact area of the semiconductor die with the circuit substrate, a low thermal resistance stacked interconnection plate atop the intimate interconnection plate for top-side cooling, a molding encapsulant for encapsulating the package except for exposing a top surface of the stacked interconnection plate to maintain effective top-side cooling. The top portion of the stacked interconnection plate can include a peripheral overhang above the intimate interconnection plate. The peripheral overhang allows for a maximized exposed top surface area for heat dissipation independent of otherwise areal constraints applicable to the intimate interconnection plate.
