Pairing Laser Ablation and Xe Plasma FIB-SEM: An approach for precise endpointing in large-scale Physical Failure Analysis in the Semiconductor Industry
Original language description
In this work we present a large-volume workflow for fast failure analysis of microelectronic devices that combines a stand-alone ps-laser ablation tool with a SEM/Xe Plasma FIB system. In this synergy, the ps-laser is used to quickly remove large volumes of bulk material while the SEM/Xe Plasma FIB is used for precise end-pointing to the feature of interest and fine surface polishing after laser. The concept of having a standalone laser tool obeys the logic of maximizing productivity as both systems can work simultaneously and continuously. As application examples we first present a full workflow to prepare an artefact-free, delamination-free cross-section in an AMOLED mobile display. We also present applications examples that require cm-sized long cuts to cut through whole microelectronic devices, or removal of cubic-mm of material to prepare mm-sized cross-sections in packages. We discuss a way how to implement correlation data across the laser and FIBSEM platforms through SYNOPSYS Avalon SW allowin
