Abstract:
1. A method of forming a semiconductor package, comprising: placing a plurality of integrated circuit (IC) dies on a first transfer film, wherein an active side of the IC dies is facing the first transfer film; performing a first molding operation to encapsulate the IC dies and one side of the first transfer film; removing the first transfer film, thereby exposing the active side of the IC dies; forming a first electrical distribution layer over the active side of each of the IC dies; performing a singulating operation to separate adjacent ones of the IC dies, thereby forming a plurality of redistributed chip package devices; placing one or more of the redistributed chip package devices on a second transfer film, wherein an active side of the one or more redistributed chip package devices is facing the second transfer film; performing a second molding operation to encapsulate the one or more redistributed chip package devices and one side of the second transfer film; removing the second transfer film, thereby exposing the active side of the one or more redistributed chip package devices; forming a second electrical distribution layer over the active side of the one or more redistributed chip package devices; and forming a plurality of conductive bumps on the second electrical distribution layer.
