Ultra Fine Pitch RDL Development in Multi-layer eWLB (embedded Wafer Level BGA) Packages

The market for portable and mobile data access devices connected to a virtual cloud access point is exploding and driving increased functional convergence as well as increased packaging complexity and sophistication. This is creating unprecedented demand for higher input/output (I/O) density, higher bandwidths and low power consumption in smaller package sizes. There are exciting interconnect technologies in wafer level packaging such as eWLB (embedded Wafer Level Ball Grid Array), 2.5D interposers, thin PoP (Package-on-Package) and TSV (Through Silicon Via) interposer solutions to meet these needs. eWLB technologies with the ability to extend the package size beyond the area of the chip are leading the way to the next level of high density, thin packaging capability. eWLB provides a robust packaging platform supporting very dense interconnection and routing of multiple die in very reliable, low profile, low warpage 2.5D and 3D solutions. The use of these embedded eWLB packages in a side-by-side configura...
