✦ Synopsis

Abstract

The alternating‐direction‐implicit finite‐difference time‐domain method is used to analyze the Metal‐Insulator‐ Semiconductor‐Metal interconnects by solving Maxwell's equations in the time domain. The dielectric quasi‐TEM mode, the slow wave mode, and the skin‐effect mode are all analyzed. This analysis shows that the silicon substrate losses and the metal line losses can be modeled with high resolution. The analysis provides attenuation and phase constant values versus semiconductor doping and frequency. We find that semiconductors readily operate in the slow wave mode and skin effect mode for selected doping densities. Accurate prediction of interconnect losses is critical to high‐frequency design with highly constrained timing requirements. © 2011 Wiley Periodicals, Inc.

Numerical models for simulation of multidimensional unsaturated flow are becoming increasingly available, but relatively little has been reported on the detailed analysis of numerical errors associated with such schemes. For unsaturated-saturated flow, further complexity is introduced to the highly
