Abstract:
1. A dice rearrangement package method, comprising: providing a first substrate having a top surface and a bottom surface, and a layer of polymer material disposed on said top surface of said first substrate; providing a plurality of dices, each said plurality of dices having an active surface and a reverse side, and a plurality of pads disposed on said active surface; picking and placing each said plurality of dices disposed on said layer of polymer material; providing a second substrate having a top surface and a bottom surface, and a layer of B-stage material is disposed on said top surface of said second substrate; performing an assembling process for said second substrate and said layer of B-stage material connecting to said top surface of said first substrate, so that said layer of B-stage material is covered each said plurality of dices; performing a baking process to make said layer of B-stage material to form a solidified encapsulated body; separating said layer of polymer material and said first substrate from said solidified encapsulated body to expose said plurality of pads on said active surface of said plurality of dices; forming a plurality of fan-out metal traces, each said plurality of fan-out metal traces is electrically connected to said plurality of pads; forming a protecting layer to cover said active surface of each said plurality of dices and each said plurality of metal traces and one ends of each said plurality of metal traces being exposed; forming a plurality of connecting components is electrically connected to another ends of each said plurality of metal traces; and cutting said encapsulated body to form a plurality of package structure independently.
