Abstract:
1. A ball grid array method, comprising: forming a reconstituted wafer about a plurality of dies; forming a plurality of voids in the reconstituted wafer, the plurality of voids extending perpendicularly from a first reconstituted wafer surface into the reconstituted wafer; filling the plurality of voids with a conductive material; forming a plurality of bars that each include a portion of the plurality of voids filled with conductive material by separating the reconstituted wafer; forming a semiconductor package by covering portions of at least one of the bars and at least one semiconductor die with a protective material; forming a first redistribution layer on a first surface of the semiconductor package, the first surface comprising an exposed portion of the first reconstituted wafer surface; and forming a second redistribution layer on a second surface of the semiconductor package, the second surface opposite the first surface; the second surface comprising an exposed portion of a second surface of the reconstituted wafer, the second reconstituted wafer surface opposite the first reconstituted wafer surface.
