Abstract:
1. A method of making a semiconductor device, comprising: providing a carrier; depositing an adhesive layer over the carrier; forming a plurality of fiduciary patterns over the adhesive layer; forming a repassivation layer over semiconductor die; forming alignment slots in the repassivation layer; leading with the repassivation layer, placing the semiconductor die onto the carrier so that the alignment slots envelope and lock to the fiducial patterns; depositing an encapsulant over the semiconductor die while the alignment slots remain locked to the fiducial patterns; removing the carrier, adhesive layer, and fiducial patterns after depositing the encapsulant; and forming an interconnect structure over the repassivation layer, the interconnect structure being electrically connected to contact pads on an active surface of the semiconductor die.
