Patent ID: 8779601

Claim:
A device, comprising: a support substrate having a front face and a back face; a first redistribution layer positioned on the front face of the support substrate, and having a first plurality of contact pads and a first plurality of electrical traces extending between respective pairs of the first plurality of contact pads; a first molding compound layer positioned on the front face of the support substrate over the first redistribution layer; a first semiconductor die having a plurality of circuit pads positioned on a front face of the first die, the first semiconductor die being substantially embedded in the first molding compound layer, the first die being positioned with the front face facing the first redistribution layer, and having the circuit pads electrically coupled to a respective one of the first plurality of contact pads; a first plurality of solder balls substantially embedded in the first molding compound layer and positioned on the first redistribution layer on a respective one of the first plurality of contact pads, a portion of each of the first plurality of solder balls lying coplanar with a face of the first molding compound layer; a second redistribution layer positioned on the face of the first molding compound layer, the second redistribution layer including a second plurality of contact pads and a second plurality of electrical traces extending between respective pairs of the second plurality of contact pads, each of the first plurality of solder balls being electrically coupled to a respective one of the second plurality of electrical traces; and a plurality of through vias located in the support substrate, each of the through vias extending from the front face of the support substrate to the back of the support substrate, each of the through vias being in electrical contact with a respective one of the first plurality of electrical traces.
