Simulation models of ESD event in ICs

ESD protection becomes more and more prevalent with the development of deep sub-micron technology. ESD simulation with right models can reduce the design and test cycle of ESD protection circuit, and optimize for ESD robustness as well as device performance. Several simulation models and practical examples are described to show the application of ESD simulation in this article. Integrated models that combine process, circuit and device simulation are the trends of development.
