Abstract: A process for manufacturing a 3D or PoP semiconductor package includes forming a redistribution layer on a reconstituted wafer, then laser drilling a plurality of apertures in the reconstituted wafer, extending from an outer surface of the reconstituted wafer to intersect electrical traces in the first redistribution layer. A solder ball is then positioned adjacent to an opening of each of the apertures. The solder balls are melted and allowed to fill the apertures, making contact with the respective electrical traces and forming a plurality of solder columns. The outer surface of the reconstituted wafer is then planarized, and a second redistribution layer is formed on the planarized surface. The solder columns serve as through-vias, electrically coupling the first and second redistribution layers on opposite sides of the reconstituted wafer.

Abstract: A semiconductor wafer has integrated circuits formed thereon and a top passivation layer applied. The passivation layer is patterned and selectively etched to expose contact pads on each semiconductor die. The wafer is exposed to ionized gas causing the upper surface of passivation layer to roughen and to slightly roughen the upper surface of the contact pads. The wafer is cut to form a plurality of semiconductor dies each with a roughened passivation layer. The plurality of semiconductor dies are placed on an adhesive layer and a reconstituted wafer formed. Redistribution layers are formed to complete the semiconductor package having electrical contacts for establishing electrical connections external to the semiconductor package, after which the wafer is singulated to separate the dice.

A ball grid array can be positioned on the second redistribution layer to couple the semiconductor package to a circuit board, or additional semiconductor dies can be added, each in a respective molding compound layer. The support wafer can act as an interposer, in which case it is processed to form TSVs in electrical contact with the first redistribution layer, and a redistribution layer is formed on the opposite side of the support substrate, as well.
