“…TSMC [29,30] presented two papers on FOWLP at ECTC2016: one is their integrated fan-out (InFO) wafer-level packaging for housing the most advanced AP for mobile applications [31], and the other is to compare the thermal and electrical performance between their InFO technology and the conventional fan-out flip chip-eWLB to make the RDLs for the chips to perform mostly lateral communications. During ECTC2016, ASE [35] and Mediatek [36] used a similar technology to fabricate the RDLs with FOWLP and showed that the TSV interposer, wafer bumping, fluxing, chip-to-wafer bonding, cleaning, and underfill dispensing and curing are eliminated, i.e., TSV-less interposers.…”
The recent advances and trends in fan-out wafer/panel-level packaging (FOW/PLP) are presented in this study. Emphasis is placed on: (A) the package formations such as (a) chip first and die face-up, (b) chip first and die face-down, and (c) chip last or redistribution layer (RDL)-first; (B) the RDL fabrications such as (a) organic RDLs, (b) inorganic RDLs, (c) hybrid RDLs, and (d) laser direct imaging (LDI)/printed circuit board (PCB) Cu platting and etching RDLs; (C) warpage; (D) thermal performance; (E) the temporary wafer versus panel carriers; and (F) the reliability of packages on PCBs subjected to thermal cycling condition. Some opportunities for FOW/PLP will be presented.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
