WebApr 6, 2024 · For FOWLP with chip-first and die face-up process, in order to make the RDLs and then mount the solder balls, the molded EMC above the Cu contact pad must be removed (Cu revealing) as shown in Fig. 6.6f. In this study, DISCO’s backgrinding machine is used to remove the EMC. WebThere are two approaches for FOWLP. Chips-first is a process whereby the chips are attached to a temporary carrier and molded to create a reconstituted wafer, which then has a buildup-layered structure deposited on the surface of the chips to create an RDL layer to interconnect the I/O pads on the chip to the ball grid array (BGA) pads.
