Abstract

See full text

A molded semiconductor package comprises a substrate, a semiconductor die mounted on the substrate, a molding compound encircling the die on the substrate, and one or more heat conductors in the molding compound that are thermally coupled to the substrate. Advantageously, the heat conductors are mounted in the molding compound near one or more of the corners of the die. The package may also include a lid. The heat conductors produce a more uniform distribution of heat in the substrate. The package is assembled by mounting the die on the substrate, mounting the heat conductors on the substrate and applying the molding compound to the substrate, the die, and the heat conductors mounted on the substrate. For packages that use a lid, the lid is then secured to the package and coupled to the heat conductors.
