Patent ID: 8642381

Claim:
A method of making a semiconductor device, comprising: providing a semiconductor wafer including a plurality of first semiconductor dies; forming a plurality of conductive pillars over the semiconductor wafer; disposing a second semiconductor die between the conductive pillars and over the first semiconductor dies; depositing an encapsulant over the first and second semiconductor dies and conductive pillars; removing a portion of a backside of the second semiconductor die and encapsulant to expose the conductive pillars; forming an interconnect structure over the backside of the second semiconductor die, encapsulant, and conductive pillars; disposing the semiconductor wafer over a temporary carrier with the interconnect structure oriented toward the temporary carrier; removing a portion of a backside of the semiconductor wafer; singulating the semiconductor wafer to the encapsulant; forming a protective layer over a plurality of exposed surfaces of the first semiconductor dies; removing the temporary carrier; and singulating the semiconductor wafer into individual semiconductor devices.
