Efficient Parameter Extraction for 3-D Structures in Layered Dielectric Media
Efficient Parameter Extraction for 3-D Structures in Layered Dielectric Media Sharad Kapur David E. Long Prashant Bell Laboratories, Lucent Technologies 600 Mountain A venue Murray Hill, NJ 07974, USA Singh Abstract Boundary element methods (BEM) are often used to extract models of integrated circuit structures. BEM extraction, however, involves solving a dense system of linear equations, and usi
