3-D chip stacking using through-silicon vias (TSVs) requires accurate characterization of the TSV, the thinned silicon, and the stacked dies. This paper proposes a set of test structures specifically designed to address the electrical characterization of TSV in terms of resistance, capacitance, leakage, yield, and their impact on the 2-D interconnects of the stacked dies. Examples of the use of these structures are presented, and the observed electrical behaviors are explained with the support of FIB cross-section images.
