Packaging method involving rearrangement of dice

A packaging method is disclosed that comprises attaching a plurality of dice, each having a plurality of bonding pads disposed on an active surface, to an adhesive layer on a substrate. A polymer material is formed over at least a portion of both the substrate and the plurality of dice and a molding apparatus is used on the substrate to force the polymer material to substantially fill around the plurality of dice. The molding apparatus is removed to expose a surface of the polymer material and a plurality of cutting streets is formed on an exposed surface of the polymer material. The substrate is removed to expose the active surface of the plurality of dice.
