In this paper, a hybrid approach for electromagnetic modeling of complex tapered through-silicon via (TSV) in three dimensional integrated circuits (3D ICs) is proposed. For complex TSV structures, TSVs are divided vertically into conical and cylindrical sections. The modeling of conical TSV is presented based on using conical modal basis functions. By using the conical TSV modeling method combined with cylindrical TSV modeling method, complex TSV structures can be modeled efficiently. The accuracy of this hybrid method is validated by comparison with 3-D full-wave simulations.
