A packaged semiconductor device has an integrated circuit (IC) die and first and second volumes of molding compound. The first volume of molding compound is disposed on a first portion of a first side of the IC die and comprises a first molding compound. The second volume of molding compound is disposed on a second side of the IC die, different from the first side, and comprises a second molding compound, different from the first molding compound. By including different molding compounds, the properties of the packaged semiconductor device can be varied across the device.
