Optimisation et modélisation de protection intégrées contre les décharges électrostatique, par l'analyse de la physique mise en jeu

Abstract : The research work presented in this thesis is aimed at improving the performance of electrostatic discharges (ESD) protection and the related design methodology for integrated circuits. To achieve this goal, a thorough analysis of the physical mechanisms involved and more precisely of high current density effects has been carried out. Such a study, focused on self-biased bipolar transistors, has been achieved with the help of 2D-numerical simulation and failure localization techniques based on laser stimulation. New universal design guidelines resulting in high performance ESD protections and original SPICE macro-models that take into account high current density effects, are proposed. Finally, the physical mechanisms limiting the performance of ESD protection networks are studied. To cope with these issues, an improved design methodology that guarantees the robustness of ESD protections used by circuit designers, is proposed.
