    Abstract: Fan Out Package-On-Package (PoP) assemblies in which a second chip is adhered to a non-active side of a first chip. An active side of the first chip embedded in a first package material may be electrically coupled through one or more redistribution layers that fan out to package interconnects on a first side of the POP. A second chip may be adhered, with a second package material, to the non-active side of the first chip. An active side of the second chip may be electrically coupled to the package interconnects through a via structure extending through the first package material. Second interconnects between the second chip, or a package thereof, may contact the via structure. Use of the second package material as an adhesive may improve positional stability of the second chip to facilitate wafer-level assembly techniques.

    Abstract: Embodiments include semiconductor packages and a method of forming the semiconductor packages. A semiconductor package includes a mold over and around a first die and a first via. The semiconductor package has a conductive pad of a first redistribution layer disposed on a top surface of the first die and/or a top surface of the mold. The semiconductor package includes a second die having a solder ball coupled to a die pad on a bottom surface of the second die, where the solder ball of the second die is coupled to the first redistribution layer. The first redistribution layer couples the second die to the first die, where the second die has a first edge and a second edge, and where the first edge is positioned within a footprint of the first die and the second edge is positioned outside the footprint of the first die.
