New de-embedding structures for extracting the electrical parameters of a through-silicon-via pair

Two innovative de-embedding methods are proposed for extracting an electrical model for a throughsilicon -via(TSV) pair consisting of a ground-signal(GS) structure.In addition,based on microwave network theory, a new solution scheme is developed for dealing with multiple solutions of the transfer matrix during the process of de-embedding.A unique solution is determined based on the amplitude and the phase characteristic of S parameters. In the first de-embedding method,a typical "π" type model of the TSV pair is developed,which illustrates the need to allow for frequency dependence in the equivalent TSV pair Spice model.This de-embedding method is shown to be effective for extracting the electrical properties of the TSVs.The feasibility of a second de-embedding method is also investigated.
