Semiconductor device and method of placing semiconductor die on a temporary carrier using fiducial patterns
Abstract:
A semiconductor device has an adhesive layer depositing over a temporary carrier. A plurality of fiduciary patterns is formed over the adhesive layer. A repassivation layer is formed over semiconductor die. The repassivation layer may be a plurality of discrete regions. Alignment slots are formed in the repassivation layer. The fiducial patterns and alignment slots have slanted sidewalls. Leading with the repassivation layer, the semiconductor die is placed onto the carrier so that the alignment slots envelope and lock to the fiducial patterns. Alternatively, a die without the repassivation layer is placed between the fiducial patterns. An encapsulant is deposited over the semiconductor die while the die remain locked to the fiducial patterns. The carrier, adhesive layer, and fiducial patterns are removed after depositing the encapsulant. An interconnect structure is formed over the repassivation layer to electrically connect to contact pads on the semiconductor die.
