Texto completoL'un des problèmes clés pour la miniaturisation des nanodispositifs à semi – conducteurs est le contrôle précis de leur dopage. Dans les dispositifs de nouvelle génération, la distribution spatiale du dopage doit être contrôlée avec une précision supérieure à 1 nm, tandis que les concentrations atomiques inférieures à 1% doivent être mesurées. Cela nécessite l'utilisation de techniques de haute résolution. La microscopie électronique à balayage en transmission (STEM) associée à la spectroscopie par rayons X à dispersion d'énergie (EDX) est un excellent candidat en raison de sa polyvalence (presque tous les éléments du tableau périodique peuvent être cartographiés) et de sa haute résolution spatiale. D'autre part, l'analyse quantitative du dopage par STEM/EDX est compliquée par la présence d'artefacts de mesure qui peuvent être ignorés sans risque pour les impuretés à haute concentration, mais deviennent critiques pour les impuretés à faible concentration. Dans cette thèse, une nouvelle méthode basée sur la méthode de de Cliff-Lorimer(C-L) a été développée pour la mesure quantitative de la distribution de dopant dans un dispositif à l'échelle nanométrique. La méthode a été appliquée sur des échantillons préparés par faisceau ionique focalisé, afin de réduire l'influence des rayons X secondaires produits par fluorescence ou par électrons rétrodiffusés, et est basée sur la correction itérative des effets d'absorption des rayons X dans l'échantillon. Afin d'obtenir des résultats fiables, les coefficients de C-L ont été étalonnés à l'aide de la mesure de Rutherford Back Scattering (RBS) et l'erreur expérimentale totale a été calculée à l'aide de techniques de propagation d'erreur standard. Les résultats obtenus sur une structure de test FinFET et sur un substrat de SiGe ayant subi des recuits laser montrent l'applicabilité de cette technique aux dispositifs à l'échelle nanométrique et avec des impuretés à faible concentration

Texto completoCrystalline orientation mapping is a key tool in material characterization, in particular for metals. For instance, orientation mapping allows to quantify the nature and size of phases in the presence, deformation state or texture. This thesis work focuses on the development of an orientation mapping approach based on the analysis of the electron channeling contrast. This contrast is obtained from electron back-scaterred imaging in a Scanning Electron Microscope. This method is called eCHORD for electron CHanneling Orientation Determination. First, the proof of concept of eCHORD is presented on an aluminum alloy and the influence of acquisition parameters is detailed. Then, two problematics are addressed: large scale orientation mapping and low voltage orientation mapping (1kV).eCHORD procedure present great interest concerning low conductivity materials on which orientation mapping are difficult to obtain and open wide perspective for ceramics studies

Texto completoThis work is devoted to the development of analytical electron tomography for the 3D chemical analysis of nanomaterials, a new technique combining the electron tomography and the energy filtered imaging within an electron microscope. By acquiring series of energy filtered images at different angular orientations of the object, their 3D chemical spatial distribution can be achieved by employing a specific reconstruction algorithm. The energy positions used for the filtering correspond to the ionization edges of the elements of interest. Owing to its double selectivity, this technique is particularly powerful when applied to heterogeneous nanomaterials. In this context, the emphasis has been put on defining a precise methodology that would be implemented at the nanometric scale. To do so, an accurate assessment of all steps of analysis as well as a fine adjustment of experimental conditions and parameters of data treatment are imperatively required. Therefore, model objects have been analyzed in a first step in order to validate our protocol. The procedure as defined was then used for the study of two classes of heterogeneous catalysts, with a spatial resolution of several nanometers. The analysis of all elemental volumes within the very same sample allowed us to quantify key-parameters governing the catalytic activity of these specimens, such as the relative proportion of the components at the surface of a grain. The 3D visualization of the chemical composition of heterogeneous nanomaterials has been already implemented for improving the catalysts synthesis methods

Texto completoDental occlusion diagnosis is still a major challenge for dentists. A couple of tools are dedicated to occlusal analysis, such as articulating papers and the T-Scan® system, but they are limited for various reasons. That's why, the goal of this thesis is to develop a novel system consisting in pressure sensor arrays on flexible substrates combining the positive aspects of both previously cited tools: an electronic and computerized system, on a very thin non-invasive flexible substrate. We chose a piezoresistive technology based on microcrystalline silicon strain gauges and 25-µm- or 50-µm-thick Kapton® substrates. Microcrystalline silicon is deposited directly on plastic at low temperature (< 200°C) using PECVD technique (Plasma Enhanced Chemical Vapor Deposition) in a cost-effective solution perspective. Strain gauges have firstly been characterized using bending tests. Longitudinal and transversal gauge factors have been studied in order to understand the behavior of our deposited materials under bending. Those gauges remained functional until strains up to 0.6 % and degradations appeared for higher values. These values correspond to bending radius on the order of 1 mm for 25-µm-thick substrates. Then, those gauges have been integrated in arrays with two different designs: one was an 800-element array to study the occlusal surface of one tooth, and the second was a 6400-element array to study the occlusal surface of a hemiarcade. Those prototypes have showed interesting correlations between articulating paper marks and our electrical responses during characterizations using a dental articulator to simulate a human jaw. Thus, we have developed in this work a proof-of-concept of a flexible strain sensor using microcrystalline silicon dedicated to dental occlusion diagnosis

Texto completoThe goal of this study is on the context of the measurement of electromagnetic rieur fields radiated by power electronics circuits. All the measurements are presented with cartographies to provide necessary information for the electromagnetic compatibility (EMC) of these devices and to improve their design. First, we have achieved a measurement bench with two automated axis. This bench was tested and calibrated by confrontations between measurements and simulations carried out for a canonical device constituted by a current loop. We have measured in low and high frequency the magnetic field radiated by a static converter with components that have variable characteristics. These measurements let us to highlight the disturbances radiated by this static converter. Ts radiation, essentially due to the commutation network's parasite inductance, cari be identified with the current loop radiation. Lastly, to improve the resolution by using a moderately sized probe and to minimize the measurement time, we propose a data post processing. It is done by deconvolution to take into account the space integration introduce by the measurement probes

Texto completoStrained silicon is now an integral feature of microelectronic devices due to the associated enhancement in carrier mobility. The general aim of this thesis is to explore how transmission electron microscopy can be used to measure strain in such systems. We show in particular how Geometric Phase Analysis (GPA) of High Resolution Electron Microscopy images (HREM) can be used to study thin layers of strained silicon grown upon virtual substrates of Si1-xGex. By studying different virtual substrate compositions and different layer thicknesses we have optimized the technique and evaluated its accuracy and reliability. Accuracy in strain measurement can reach 0. 2% for fields of view of 200 nm x 200 nm. The detailed comparison of experimental measurements and finite element simulations allows the quantification of thin foil relaxation for TEM lamellas. We show, for the first time, that strain can be mapped in two dimensions in an actual device, a p-MOSFET, with a spatial resolution of 2 nm. The second part concerns a new method developed in the CEMES-CNRS laboratory: dark-field holography. With the aid of a field emission gun and a biprism, interferometric fringes are created between a diffracted wave coming from a perfect crystal and a diffracted wave coming from a distorted area. Analysis of the hologram allows us to determine strain. Very large field of view (500 nm by 2 µm) can be obtained with an even better precision than HREM: 0. 02%. Finally, the complementarity of the two techniques is demonstrated through the study of various systems such as multichannel, uniaxial compressed p-MOSFETs (SiGe) with different channel lengths or uniaxial tensile strained n-MOSFETs (Si:C)

Texto completoThis thesis has for objective the writing of a data-processing code allowing the determination of the electromagnetic field in a Reverberation Chamber (RC), using harmonic mode. The principal difficulty in this project is the quantity of useful data-processing resources, especially in the used frequencies range. The developed method is a hybridization using the FDFD/Waveguide mode expansion. The interest of hybridization is to net only part of the interior zone of the enclosure. In the diffraction zone, the finite difference in frequency domain (FDFD) is applied, whereas the electromagnetic field is expanded on a basis of functions in the measurement zone. We define a scalar product utilizing only the longitudinal component of the field, in a cross-section of the cavity. We show that the basic functions then define an orthogonal basis. The originality lies in obtaining the basic functions by numerical calculation (in opposition to analytical), in cases of section of an unspecified form. The validations are carried out by comparison with the analytical ones (without stirrer) and by rebuilding of field cartographies, this for enclosures with rectangular and circular section. The carried out code makes it possible to obtain the weights of the various modes. When the stirrer is present, the validation is statistical and we confirm the laws followed by the various rectangular components and the modules of the field. We note the fundamental role of the losses, defined by the quality factor of the CR for the statistical laws verification

Texto completoAt the beginning of our research in 2010, there was great interest in the advent of the digital era and its impact in the field of cultural heritage. In light of this and the increasingly numerous debates about it, we wondered what “digital phenomena” adds to (or detracts from) the cultural heritage experience. The change of support does not necessarily (rarely even) changes heritage mediation practices, therefore, for the purposes of this research, the term digital refers not to digital technology but the concept of “digital” as a social phenomenon with everything that this implies through speeches, imagination, practices and expectations. To move beyond the discussions about technology, we have chosen to study a limited number of fields (the Cité Internationale Universitaire de Paris and the Mont-Royal in Montreal) and opt for a socio-semiotic approach. This thesis shows that a same device, the interactive map, can offer multiple possibilities for cultural mediation, between documentary mediation and cultural mediation. It also calls into question a possible reconfiguration of the roles of mediator and visitor in the digital forum: far from upsetting the function and identity of heritage institutions, digital devices implemented in these two fields strengthen their legitimacy as cultural mediators
Vives, Gilabert Yolanda. "Modélisation des émissions rayonnées de composants électroniques". Rouen, 2007. http://www.theses.fr/2007ROUES025.
Texto completoThis thesis, performed in IRSEEM in collaboration with Thales Air Systems, is included in the program « EMC of components » from the Normandie AéroEspace cluster. This thesis work is based on the development of models of the magnetic field radiated by electronic components. These models must be generic (i. E. The procedure of modeling must be able to be applied to any component) and insertable into the commercial electromagnetic softwares, like HFSS and CST Microwave Studio. In order to do that, a first model based on a set of elementary dipoles (electric or magnetic dipoles) is developed, being the procedure to obtain this model relatively simple. It is based on the inversion of some matrices with the least square method. The application of this model to different devices (self, oscillator. . . ) gives good results, both in amplitude and phase of the magnetic field. However, this model is very rigid due to the great number of parameters that are fixed by the user. Moreover, the huge quantity of sources in the model complicates the insertion into commercial simulation software. It is for this reason that a second approach of modeling, better adapted to our problematic, has been developed. His second model is composed of a set of a maximum of 10-12 dipoles. In this case the procedure of modeling is based on two different techniques : the application of a function usually used for the treatment of digital images and the application of an optimisation algorithm. This procedure is more flexible than the previous one because it is capable of calculating all the parameters of the model. However, the accuracy of the model is inevitably reduced due to the fact that the number of dipoles has been also reduced
