Patent ID: 8072059

Claim:
A method of making a semiconductor device, comprising: providing a temporary carrier; forming a first conductive layer over the temporary carrier; forming an under bump metallization (UBM) layer over the temporary carrier, the UBM layer being fixed in position relative to the first conductive layer; forming a conductive pillar over the first conductive layer; mounting a semiconductor die to the UBM layer to align the semiconductor die relative to the conductive pillar; depositing an encapsulant over the semiconductor die and around the conductive pillar, the UBM layer preventing shifting of the semiconductor die while depositing the encapsulant; removing the temporary carrier; forming a first interconnect structure over a first surface of the encapsulant; and forming a second interconnect structure over a second surface of encapsulant opposite the first interconnect structure, the first and second interconnect structures being electrically connected through the conductive pillar.
