In this paper, a Quasi-Multiple Medium (QMM) acceleration method based on direct boundary element method is proposed and applied to the calculation of three-dimensional VLSI multi-media interconnect capacitors. The QMM method considers a single-layer medium in a three-dimensional interconnected capacitor to be composed of a plurality of virtual media, thereby greatly reducing the number of non-zero elements in the coefficient matrix, and ultimately reducing computation time and storage space significantly. By comparing the QMM algorithm with non-QMM algorithm and the commercial software Raphael's calculation of the actual three-dimensional interconnection structure, the results show that the QMM calculation can significantly improve the efficiency of capacitance extraction while maintaining the accuracy of calculation.
