摘要：
Different milling strategies for the structural characterization of through silicon vias on silicon wafers and in stacked dies are examined. For investigation of the filling quality, the most appropriate analysis technique is dual beam focused ion beam and scanning electron microscopy. The characterization of thin barriers and Cu seed layers requires transmission electron microscopy. An optimized TEM specimen preparation method is discussed.
