This algorithm leads to a significant reduction in CPU time and storage requirements as compared with the conventional FDTD method.

A novel double-image Green's function approach combined with the hierarchical algorithm is proposed to compute the frequency-dependent capacitance and conductance for the on-chip transmission lines and interconnects embedded in Multiple SiO2 layers of the general CMOS process. The effect of a protective layer and lossy silicon substrate layer of the CMOS process are considered in the four-layer structure deduced by the equivalent dielectric-constant approach whose adaptability is further proven in this paper. This double-image Green's function approach is fast convergent with the increasing order of reflections and transmissions, which is further accelerated by the hierarchical algorithm for computation of the Green's function rapidly. Moreover, the proposed method avoids the computation of bound charges on the dielectric interfaces. The frequency-dependent capacitance and conductance gained from the proposed method are shown to be in good agreement with the data obtained by other relevant methods.

An efficient method based on a direct boundary element method is proposed for extracting frequency-dependent substrate coupling parameters. A frequency-independent real-valued linear equation system is first solved. Then, the solution is transformed into frequency-dependentparameters at a specified frequency with the Sherman-Morrison-Woodbury formula. The first step is performed only once for a given structure, and the method is very efficient for extraction with multiple frequencies. The proposed method is compared with the Green's function-based method and the approach in our earlier paper for typical substrate structures. Numerical results demonstrate its accuracy, efficiency, and versatility.
