Claim:
1. A semiconductor device comprising: an integrated circuit die including a first side and a second side opposite the first side; a contact pad disposed on the first side of the integrated circuit die; a passivation layer disposed over the first side of the integrated circuit die, the passivation layer including a first opening in the passivation layer over the contact pad; a polymer layer disposed over the passivation layer, the polymer layer including a second opening in the polymer layer over the contact pad; a molding material disposed around the integrated circuit die, the passivation layer, and the polymer layer, wherein an upper surface of the molding material is level with an upper surface of the polymer layer; and a redistribution layer (RDL) disposed over the molding material and the polymer layer, wherein a conductive portion of the RDL extends through the second opening in the polymer layer and through the first opening in the passivation layer to contact the contact pad.
