This paper focuses on the link between initial electrical resistance of Through Silicon Via (TSV), and possible failure occurring during Thermal Cycling Test (TCT) and electromigration (EM) tests. Physical analyses reveal the presence of a carbon impurity layer at bottom of the higher resistance TSVs. This impurity induces failure during TCT, but has no(More)
4µm wide copper Through Silicon Vias (TSV) were processed on underlying 65nm CMOS devices and circuits in order to evaluate the impact of the three-dimensional (3D) integration process. Electrical tests on isolated MOSFET and ring oscillators in the presence of TSVs are compared to modeling results. Beside TSV mechanical impact, an electrical(More)
