Full textRoughness at Sub-nanometric scale determination becomes a critical issue, especially for patterns with critical dimensions below 10nm. Currently, there is no metrology technique able to provide a result with high precision and accuracy. A way, based on hybrid metrology, is currently explored and dedicated to dimensional measurements. This hybrid metrology uses data fusion algorithms in order to address data coming from different tools. This thesis presents some improvements on line roughness analysis thanks to frequency decomposition and associated model. The current techniques used for roughness determination are explained and a new one SAXS (Small Angle X-rays Scattering) is used to push again limits of extraction of roughness. This technique has a high potential to determine sub nanometrics patterns. Moreover, the design and manufacturing of reference line roughness samples is made, following the state of art with periodic roughness, but also more complex roughness determined by a statistical model usually used for measurement. Finally, this work focus on hybridization methods and more especially on neural network utilization. Thus, the establishment of a neural network is detailed through the multitude of parameters which must be set. In addition, training of the neural network on simulation leads to the capability to generate different metrology

Full textThe inertial confinement fusion experiments require cryogenics targets fabrication, which is mainly a smooth uniform solid hydrogen isotopes (DT) layer at 20K. This layer is modelled in a plastic microshell that is placed in a gold cavity. One of the challenges of this program is to guarantee roughness and uniformity of the layer. Similar objects does not exist at ambient temperature. This report presents three methods convenient to characterise this layer in cryogenic conditions, with only one observation direction. The first one, shadowgraphy consists of the observation of the microshell thank to an optical system. The analyse of shadowgraph allows the DT layer characterisation in an equatorial plan. The two others techniques are the optical coherent tomography and the wide band interferometry. These methods provide the measurement of the layer thickness at the poles of microshell. The interference patterns are formed by the interference on two waves. The first one is reflected on a reference mirror, the second one is reflected on the interfaces of the microshell. The performances and uncertainties of the methods are analysed

Full textThe water issue is currently a major challenge for our societies. Even if water is a renewable resource, its natural cycle supports great stresses, both human activity and climate change.River discharge is a key variable of the water cycle, whose quantification requires heavy field measurements. Therefore the global monitoring of river discharge remains problematic and satellite remote sensing techniques could be a major asset. Earth Observation radar techniques are currently limited to the measurement of surface variables and cannot measure river bottom hydraulic parameters. The current study proposes a method to estimate these parameters from surface variables, in order to estimate the river discharge. This method has been validated on exact simulated data and its robustness to measurement noise has been studied on noisy simulated data and on real data.The second part of this work explores the abilities of radar along-track interferometry to measure river surface velocity. Velocity measurements carried out on the Rhône river during an airborne campaign (ONERA-Cemagref) show a strong consistency with ADCP field measurements. M4S backscattering model, tested in the framework of this study, is poorly adapted to river scenes : it appears to be extremely sensitive to wind intensity which could be explained by a poor modeling of surface roughness. As part of the SWOT mission program (NASA-CNES) a method allowing in situ characterization of river surface roughness has been developed. It was validated under laboratory controlled conditions. It was implemented on the Rhône river to characterize water surface and quantify the influence of wind intensity on the water surface roughness parameters

Full textThe monitoring and control of the surface are important issues in several areas in Mechanics. Many studies are ongoing to understand the interactions between the surface morphology and the physical mechanisms, chemical or mechanical. A key aspect that still needs improvement is the accurate characterization of surfaces, according to areas and needs, especially when it cornes to extracting the most relevant parameters for characterizing surface and define the level most appropriate for it. The aim of this project is to construct a methodology for processing bidimensional parameters (profiling) which allows, using an expert system to give the user the parameter of surface state associated with optimal desired functionality. We present in this paper the philosophy and methodology of building the system architecture that we called "MesRug". We also explain the technology used for the realization of this system, how to use it and enrich it with new multi-scale characterization of surfaces and new roughness parameters. We also present some developments and analyzes multi-scale integrated into the system "MesRug" to determine the characteristics of a set of elements (scale of measurement, parameter, lifter, to better discriminate the desired property, statistical methods used to determine the relevance of roughness parameters, and applications for various studies conducted using this approach
