Equivalent mechanical properties of through silicon via interposers  A unit model approach
We homogenize the TSV interposer into an equivalent transversely isotropic model. A closed-form description of the equivalent mechanical properties is presented. A transversely isotropic stiffness matrix for the equivalent model is presented. Sensitivity analysis was conducted to account for interposers with tapered vias.
