Abstract

We have enhanced the process simulator CODEF[2] into a tool called CARAMEL (ContaminationAnd Reliability Analysis of MicroElectromechanicalLayout) for analyzing the impact of contamination particles on the geometrical and material properties of microelectromechanical systems (MEMS).CARAMEL accepts as input a microelectromechanicallayout, a particulate description, and a process recipe.CARAMEL produces a mesh description of the defective layout that is completely compatible with theelectromechanical simulator ABAQUS [31]. Analysisof CARAMEL's output indicates that a wide range ofdefective structures are possible due to the presence ofcontaminations. Moreover, electromechanical simulations of CARAMEL's mesh representations of defective layout has revealed that a wide variety of faultybehaviors are associated with these defects. In this paper, we describe CARAMEL and its application to thedevelopment of realistic fault models for MEMS.
