Abstract
A semiconductor package includes a substrate, a semiconductor die, dendrite, and a mold material. The substrate includes a die pad. The die pad includes roughening features. The semiconductor die is attached to the die pad such that the roughening features are adjacent to the semiconductor die. The dendrite is on the roughening features adjacent to the semiconductor die. The mold material encapsulates the semiconductor die, the dendrite, and at least a portion of the substrate.
