Fan-Out Wafer Level Package Structure
First Claim
1. A method for forming a package structure, comprising:
- applying a die over a carrier, the die having a plurality of mounts;
providing one or more vias on the carrier;
forming a molded substrate over the carrier and around the vias;
reducing a first side of the molded substrate opposite the carrier and exposing the one or more vias at a first side of the molded substrate opposite the carrier;
forming a redistribution layer (RDL) on the first side of the molded substrate, the RDL having a plurality of RDL contact pads; and
exposing the one or more vias at a second side of the molded substrate opposite the first side.

Abstract
A method for forming a package structure may comprise applying a die and vias on a carrier having an adhesive layer and forming a molded substrate over the carrier and around the vias, and the ends of the vias and mounts on the die exposed. The vias may be in via chips with one or more dielectric layers separating the vias. The via chips 104 may be formed separately from the carrier. The dielectric layer of the via chips may separate the vias from, and comprise a material different than, the molded substrate. An RDL having RDL contact pads and conductive lines may be formed on the molded substrate. A second structure having at least one die may be mounted on the opposite side of the molded substrate, the die on the second structure in electrical communication with at least one RDL contact pad.
