Texto completoThe aim of this work is to improve the performance, cost and area of a microcontroller manufactured in a 40 nm CMOS embedded memory technology (eNVM), by developing new transistor architectures suitable for the IoT market. The context is first presented with a focus on the technological and economical limitations of the CMOS technology. In a second part, the eNVM manufacturing process as well as the architecture and operation mode of a new component called triple gate transistor are presented. Based on this new architecture which provides independent control gates, various multigate transistors are manufactured and their electrical behaviour is analysed. Reliability studies are then carried out, to assess the reliability of the gate’s oxides. The objective is to study the impact of an electrical stress applied to one transistor gate on the gates not subject to this same stress. Electrical characterizations and TCAD simulations are also conducted to improve the understanding. Finally, the structure of the triple gate transistor is modelled using a compact PSP transistor model. The aim is to evaluate the behaviour but also the electrical performance of this transistor at the circuit level

Texto completoCMOS image sensors showed in the last few years a dramatic reduction of pixel pitch. However pitch shrinking is increasingly facing crosstalk and reduction of pixel signal, and new architectures are now needed to overcome those limitations. Our pixel with Capacitive Deep Trench Isolation and Vertical Transfer Gate (CDTI+VTG) has been developed in this context. Innovative integration of polysilicon-filled deep trenches allows high-quality pixel isolation, vertically extended photodiode and deep vertical transfer ability. First, specific process steps have been developed. In parallel, a thorough study of pixel MOS transistors has been carried out. We showed that capacitive trenches can be also operated as extra lateral gates, which opens promising applications for a multi-gate transistor compatible with CMOS-bulk technology. Finally, a 3MPixel demonstrator integrating 1.75*1.75 μm² pixels has been realized in a CMOS 120 nm technology. Pixel performances could be measured and exploited. In particular, a low dark current level could be obtained thanks to electrostatic effect of capacitive isolation trenches

Texto completoThe objective of this thesis was to develop a new generation of EEPROM memory for high reliability and high density applications. First, an innovative memory cell developed by STMicroelectronics - eSTM (Split-gate charge storage memory with buried vertical selection transistor) - was studied as a reference cell. In a second part, to improve the reliability of the eSTM cell and to allow a more aggressive miniaturization of the EEPROM cell, a new memory architecture has been proposed: the BitErasable cell. It showed an excellent reliability and allowed to bring elements of under-standing on the degradation mechanisms present in these memory devices with buried selection transistor. This new architecture also offers the possibility to individually erase cells in a memory array: bit by bit. Aware of the great interest of bit-by-bit erasing, a new erasing mechanism by hot hole injection has been proposed for the eSTM cell. It has shown performances and a level of reliability perfectly compatible with the industrial requirements of Flash-NOR applications

Texto completoIGBTs are currently used in rail train 1200 Volts power converter. These are disabled by important switch losses and thermal surge. Substitute IGBTs by power MOSFETs would enable to overcome these drawbacks. However, in this voltage range, MOSFETs are penalized by the "Breakdown voltage / On-state resistance" trade-off. As part of this thesis works, we have studied many principles to invent a new powerful MOSFET structure. We have chosen a Superjunction structure, made by deep trench etching and boron diffusion. Theoretically, this structure exhibits 13 m?. Cm2 for 1200 V. The main part of the work was to optimize this structure. For this, we have studied many technological parameter's influence on "Breakdown voltage / On-state resistance" the trade-off. We have developed a new innovated junction termination in order to sustain the desired breakdown voltage. It was necessary to identify the process critical steps. From this point, we have fabricated a 1200 V diode which enabled to validate some of these steps

Texto completoDue to good performances, small size, or either integration possibilities very close to transistors,electromechanical resonators offer a strong potential for quartz replacement in time reference applications. In this context, we propose to develop electromechanical resonators in a perspective of a front-end integration, for the realization of integrated oscillators. The fabricated demonstrators are based on the Silicon On Nothing CMOS technology, under R&D at STMicroelectronics. Due to the small size of the studied components, a resonant gate transistor was used to amplify the resonance detection. Specific technological developments enabled the fabrication of both resonator and detection transistor. Device conception was made by the use of an electromechanical resonator model, developed during the study. Thurthermore, the model is compatible with design tools, making it usefull for MEMS oscillator conception.Then, we demonstrated resonator and MOSFET detection amplification well-functionning on the fabricated devices.This is the first demonstration of MOSFET detection functionality for a small size and in-plane vibrating component. Finally, the electromechanical model was validated with other models and measurements. In terms of perspectives, the use of various design or technology improvements could able the access to devices compatible with the realization of a high perfromances and co-integrated oscillator

Texto completoAnalysis and systems design in power electronics must taking into account of specific complex phenomena to each components of the system but also in agreement with its environment. Accurate description of a system needs for simulations sufficiently accurate models of all its components. In our study, the models based on the semiconductor physics make it possible to describe the behavior of the stored charge in the deep and low doped base in the bipolar devices. This fine description is essential to the good precision of our models because the evolution of the carriers in the base is indissociable of the in static and dynamic behaviors of the component. Thus, the analytical physical models of PiN diode, NPT or PT IGBT with planar or trench gate structure are presented then validated. The modeling of complex systems in power electronics is approached through two studies. The first deals with to the association of our semiconductor models and wiring model of an industrial power module (3300V /1200A). An analysis on imbalances between the different chips in parallel is given. The second study presents a innovating architecture resulting from the functional integration. This low losses improve the tradeoff between on-state drop voltage and turn-off transient energy in IGBT component. Its technological realization is presented through measurements
