Abstract
The introduction of fine-line interposers or packaging technologies with a redistribution layer (RDL) can significantly relax the fine-line spacing requirements on the PCB. One of these fan-out wafer-level packaging technologies is the embedded wafer-level ballgrid-array (eWLB) package, which features a number of favorable high-frequency characteristics. It is optimized in terms of the requirements for high integration density with a large number of external interfaces and has been developed by the companies Infineon Technologies, ST Microelectronics, and STATS ChipPAC. This eWLB packaging technique represents a tradeoff between both a chip-level packaging and a wafer-level packaging approach.
