Investigation and Methods Using Various Release and Thermoplastic Bonding Materials to Reduce Die Shift and Wafer Warpage for eWLB Chip-First Processes


Today's fan-out wafer-level packaging (FOWLP) processes use organic substrates composed of epoxy mold compound (EMC) created using a thermal compression process. EMC wafers are a cost-effective way to achieve lower profile packages without using an inorganic substrate to produce chip packages that are thinner and faster without the need for interposers or through-silicon-vias (TSVs). One approa... » read more

Material Solutions For FOWLP Die Shift And Wafer Warpage

Lithography Challenges For Fan-out


Higher density fan-out packages are moving toward more complex structures with finer routing layers, all of which requires more capable lithography equipment and other tools. The latest high-density fan-out packages are migrating toward the 1µm line/space barrier and beyond, which is considered a milestone in the industry. At these critical dimensions (CDs), fan-outs will provide better per... » read more

Litho Options For Panel Fan-out


Several packaging houses are inching closer to production of panel-level fan-out packaging, a next-generation technology that promises to reduce the cost of today’s fan-out packages. In fact, ASE, Nepes, Samsung and others already have installed the equipment in their panel-level fan-out lines with production slated for 2018 or so. But behind the scenes, panel-level packaging houses contin... » read more
