FOWLP: Chip-First and Die Face-Down

  • John H. Lau


The first fan-out wafer-level packaging (FOWLP) U.S. patent was filed by Infineon on October 31, 2001 (Hedler et al. in Transfer Wafer Level Packaging, 2001 [1]; Lau in Chip Scale Rev. 19:42–46, 2015 [2]), and the first technical papers were also published (at ECTC2006 and EPTC2006) by Infineon and their industry partners: Nagase, Nitto Denko, and Yamada (Brunnbauer et al. in IEEE/ECTC Proceedings, 547–551, 2006 [3]; Brunnbauer et al. in IEEE/EPTC Proceedings, 1–5, 2006 [4]). At that time, they called it embedded wafer-level ball (eWLB) grid array.
