FOWLP: Chip-Last or RDL-First

  • John H. Lau


Since 2006, NEC Electronics Corporation (now Renesas Electronics Corporation) has been developing a novel SMAFTI (SMArt chip connection with feedthrough interposer) packaging technology for inter-chip wideband data transfer, 3D stacked memory integrated on logic devices, system in wafer-level package (SiWLP), and “RDL-first” fan-out wafer-level packaging. In this chapter, three RDL (redistribution layer) fabrication methods for chip-last FOWLP (fan-out wafer-level packaging) are briefly mentioned.
