Full textAs part of this study focuses on the development of external protection against electrostatic discharge (ESD) to the electronic components to protect. For many applicative reasons where taken area becomes a major concern, the ESD protection must meet size constraints increasingly difficult to satisfy while keeping the same performance in robustness. This work presents a new concept of bi-directional ESD protection structure based on industrial technology originally dedicated to achieving high-density integration capabilities. The technological process has a deep trench production step which is used in this study for the realization of three-dimensional diodes. Optimizing configuration of the structure was conducted by a theoretical study using TCAD simulation tools to better understand the physical functioning and provide design rules. Many experimental results are presented and comparisons will also be conducted to quantify the contribution of this new technology. The best configuration ensures a 25% reduction in the size of structures while ensuring a high level of robustness

Full textWith improvement in electronic technology shrinking, electronic components are increasingly becoming sensitive to ElectroStatic Discharge (ESD). Nowadays, the reliability of integrated circuits in the manufacturing field are guaranteed by a set of standards that define levels of robustness. Nevertheless the protection strategies implemented in integrated circuits, designed to meet these standards, are not always enough to ensure the robustness of the components in their final application. The new reliability problems are not well understood, given the complexity of the phenomena involved in real systems in operation. Taking into account these facts, we can question the effectiveness of the strategies used to protect against " classical ESD " and system-type stresses. All the work presented in this thesis aims to improve the robustness with respect to these new requirements, in the case study of analog components dedicated to portable applications (telephony, multimedia). Starting from a concrete case, for which there is a large difference in the system ESD robustness between the biased and unbiased product, we will present the various results of analysis (failure analysis, electrical characterization by impulse like TLP VFTLP, SPICE-type simulations) that led us to the proposal of an integrated security solution that meets the requirements

Full textMiniaturization of electronic circuits continues nowadays with the more recent technology nodes being applied to diverse fields of application such as automotive. Very dense and small integrated circuits are interesting for economic reasons, because they are cheaper to manufacture in mass and can pack more functionalities with elevated performances. The counterpart of size reduction is integrated circuits becoming more fragile electrically. In the automotive world, the new trend of fully autonomous driving is seeing tremendous progress recently. Autonomous vehicles must take decisions and perform critical actions such as braking or steering the wheel. Those decisions are taken by electronic modules, that have now very high responsibilities with regards of our safety. It is important to ensure that those modules will operate no matter the kind of disturbances they can be exposed to. The automotive world is a quite harsh environment for electronic systems. A major source of electrical stress is called the Electrostatic Discharge (ESD). It is a very sudden flow of electricity of large amplitude capable of destroying electronic components, or disturb them during their normal operation. This research focuses on functional failures where functionality can be temporarily lost after an ESD with various impact on the vehicle. To guarantee before manufacturing that a module and its components will perform their duty correctly, new analysis and prediction methods are required against soft-failures caused by electrostatic discharges. In this research, different approaches have been explored and proposed towards that goal. First, a modelling method for reproducing the ESD waveforms from the test generator up to the integrated circuit input is presented. It is based on a hierarchical approach where each element of the system is modelled individually, then added to the complete setup model. A practical case of functional failure at silicon-level is analyzed using simulation tools. To acquire more data on this fault, a testchip has been designed. It contains on-chip monitoring structures to measure voltage and current, and monitor function behavior directly at silicon-level. The last part of this research details different analysis methods developed for identifying efficiently functional weaknesses. The methods rely heavily on simulation tools, and prototypes have been implemented to prove the initial concepts. The first method models each function inside the chip individually, using behavioral models, then enables to connect the models together to deduce the full function's robustness. It enables hierarchical analysis of complex integrated circuit designs, to identify potential weak spots inside the circuit that could require more shielding or protection. The second method is focused on constructing equivalent electrical black box models of integrated circuit functions. The goal is to model the IC with a behavioral, black-box model capable of reproducing waveforms in powered conditions during the ESD. In summary, this research work has led to the development of several hardware and software prototypes. It has also highlighted important modelling challenges to solve in future works to achieve better functional robustness against electrostatic discharges
