Large area compression molding for Fan-out Panel Level Packing

Abstract

Fan-out Wafer Level Packaging (FOWLP) is one of the latest packaging trends in microelectronics. Mold embedding for this technology is currently done on wafer level up to 12″/300 mm diameter. For higher productivity and therewith lower costs larger mold embedding form factors are forecasted for the near future. Following the wafer level approach then the next step will be a reconfigured wafer size of 450 mm. An alternative option would be leaving the wafer shape and moving to panel sizes leading to Fan-out Panel Level Packaging (FOPLP). Sizes for the panel could range up to 24″x18″ or even larger. For reconfigured mold embedding, compression mold processes are used in combination with liquid, granular or sheet compound. As a process alternative also lamination as used e.g. in PCB manufacturing can be taken into account.
