Thin fan-out multi-chip stacked packages and the method for manufacturing the same
A fan out type multi-chip stacked package includes a chip stacked assembly having a plurality of chips vertically stacked. The electrodes of the chips and one active surface among all active surfaces are not covered by the stacked chips. A plurality of flip-chip bumps of a dummy flip chip are coupled to the electrodes of the chips. An encapsulant encapsulates the chip stacked assembly and the flip-chip bumps. The encapsulant has a planar surface. The flip-chip bumps have a plurality of bonding surfaces exposed from and coplanar to the planar surface. A redistribution layer is disposed on the planar surface and includes a plurality of fan out circuits electrically connected the bonding surfaces of the flip-chip bumps. Thus, the package has better resistance against mold flow impact to effectively reduce the risk of wire sweeping.
