Abstract:
1. A method of making a semiconductor device, comprising: providing a semiconductor wafer containing a plurality of first semiconductor die; mounting a plurality of second semiconductor die to a first surface of the semiconductor wafer; placing a tape on a second surface of the semiconductor wafer opposite the first surface of the semiconductor wafer; forming a protective material over the second semiconductor die and first surface of the semiconductor wafer; singulating the semiconductor wafer between the second semiconductor die into individual die-to-wafer packages each containing the second semiconductor die stacked on the first semiconductor die, the protective material protecting the semiconductor wafer during singulation; removing the tape; mounting the die-to-wafer package to a substrate; removing the protective material to expose the second semiconductor die and first surface of the semiconductor wafer; and depositing an encapsulant over the die-to-wafer package and substrate.
