Abstract
Due to the semiconductor technology progresses, the process technology improves from .18μm to 90nm, even 65nm. So making high-performance and low-volume chip is a trend. Resistance problems exists in every circuit, especially in high-performance low-volume chip, resistance problems will be even serious than before, such as RC delay, IR drop or substrate coupling. In order to estimate these resistance problem efficient and accurately, software simulation before taping out is necessary. In this thesis we will introduce a field solver called Raphael to help us about the resistance extraction. We will explain the basic knowledge about Raphael and conductance matrix, then show the correctness of Raphael and its application on resistance problems to help IC design. Finally, we will show a way to enhance the speed of resistance extraction in large circuit design.
