Patent ID: 8021981

Claim:
A method for processing a microfeature workpiece system, comprising: stacking a substrate having a first surface, a redistribution layer at the first surface, a second surface facing opposite from the first surface, a first conductive via extending entirely through the substrate and electrically connected to the redistribution layer, and no operable microfeature devices, relative to a microfeature workpiece having a first surface, a second surface facing opposite from the first surface of the microfeature workpiece and a die with at least one operable microfeature device positioned between the first and second surfaces of the microfeature workpiece and electrically coupled to a second conductive via extending entirely through the microfeature workpiece, the second surfaces of the substrate and the microfeature workpiece facing toward each other, the redistribution layer of the substrate facing opposite from the first surface of the microfeature workpiece, the first and second conductive vias being laterally aligned; and electrically connecting the first and second conductive vias proximate to the second surface of the substrate and second surface of the microfeature workpiece.
