Claim:
1. A method comprising: forming a mold compound over a semiconductor die, the die being over a front side redistribution layer on a side opposite the mold compound, the redistribution layer extending past the die and the mold compound extending around the die to contact the redistribution layer; forming a plurality of vias around the die in the mold compound vertically toward the redistribution layer, the vias being outside of the die with gaps between the vias of the plurality of vias, wherein the bottoms of the vias are over a ground layer of the front side redistribution layer, the via gaps configured to form a Faraday cage around the die; and applying a continuous conductive shielding film over the mold compound and into the vias, wherein the shielding film in some of the vias directly connects to the ground layer and wherein the shielding film in some of the vias does not directly connect to the ground layer, the redistribution layer connecting the shielding film to an external ground so that the vias form a shield.
