Abstract:
1. A method for manufacturing a semiconductor device comprising: flip chip mounting a first side of a semiconductor die to a substrate comprising a plurality of conductive traces, wherein a second side of the semiconductor die is subjected to one of polishing, etching, and grinding to reduce a thickness of the semiconductor die to be no greater than 2 mils prior to the flip chip mounting; encapsulating the semiconductor die and substrate with an encapsulating material; subjecting a top side of the encapsulating material to one of polishing, etching, and grinding to expose the second side of the semiconductor die; subjecting the bottom side of the substrate to one of polishing, etching, and grinding to remove the substrate; and reducing a thickness of the plurality of conductive traces by continuing the one of polishing, etching, and grinding after the substrate has been removed, wherein the substrate is removed and then the thickness of the plurality of conductive traces is reduced in one continuous step.
