Abstract:
MOS capacitors with TiO2 and TiO2/SiO2 dielectric layer were fabricated and characterized. TiO2 films where physical characterized by Rutherford Backscattering, Fourier TransformInfrared Spectroscopy and Elipsometry measurements. Capacitance-voltage (1MHz) and current voltage measurements were utilized to obtain, the effective dielectric constant, effective oxide thickness (EOT), leakage current density and interface quality. The results show that the obtained TiO2 films present a dielectric constant of approximately 40, a good interface quality with silicon and a leakage current density, of 70 mA/cm2 for VG = 1V, acceptable for high performance logic circuits and low power circuits fabrication, indicating that this material is a viable substitute for current dielectric layers in order to prevent tunneling currents.

Abstract:
Filmes finos de LiNbO3 foram preparados pelo método dos precursores poliméricos e depositados por "spin coating" sobre substratos de safira (0001). Os filmes foram tratados em forno microondas doméstico a 400 ºC por 15 e 20 min. Um material com alta perda dielétrica (susceptor de SiC) foi usado para absorver energia das microondas e transformá-la em calor. Este calor foi transferido para o filme a fim de promover a sua cristalização. O susceptor foi posicionado acima do filme ou embaixo do substrato. Desta forma, a influência da direção do fluxo de calor na cristalização das amostras foi verificada. Os filmes foram caracterizados por difração de raios X, microscopia de força atômica e espectrofotometria (transmitância) na região UV-visível e o índice de refração foi determinado por elipsometria. O crescimento epitaxial foi observado para o filme com susceptor posicionado embaixo do substrato. Verificou-se que os grãos apresentaram crescimento aleatório quando o susceptor foi posicionado acima do filme. Os filmes apresentaram-se relativamente densos, homogêneos e lisos, com boas propriedades ópticas.

Se estudiaron las características eléctricas de películas delgadas de óxido de aluminio preparadas por la técnica de rocío pirolítico ultrasónico. Las películas delgadas se depositaron a partir de una solución de acetilacetonato de aluminio en N,N-dimetilformamida sobre substratos monocristalinos de GaAs (100) tipo-p. La temperatura de depósito fue de 300 a 600 ºC. Las propiedades eléctricas de las películas en función de la temperatura de substrato se determinaron por medidas de capacitancia y corriente contra voltaje mediante la incorporación de las películas en estructuras tipo MOS (metal-óxido-semiconductor). La densidad de estados de interfaz resultó del orden de 10(12) 1/eV-cm² y el dispositivo MOS soportó campos eléctricos mayores a 5MV/cm, sin mostrar rompimiento dieléctrico. El índice de refracción se determinó por elipsometría a 633nm, con un valor máximo del orden de 1.64.

Abstract:
Filmes finos de PMMA foram preparados a partir de solução e expostos ao plasma de CF4+H2, visando mudar o Índice de Refração (I.R.) da superficie do PMMA através da fluoração. Os filmes de PMMA expostos ao plasma, denominados de filmes ópticos, foram caracterizados usando as técnicas: ESCA, RBS, FTIR, gravimetria, ângulo de contato, refratometria e elipsometria. Os resultados revelaram que as superfícies de PMMA foram revestidas com uma fina camada de hidrofluorcarbono polimérico, com espessuras variando entre 0,43 e 0,49mim. A camada de hidrofluorcarbono polimérico na superfície do PMMA foi responsável pela significante redução do seu I.R. de 1,49 para 1,43. A concentração de flúor nessa camada aumentou gradualmente em função da profundidade, sendo menor na sua superficie. Como o átomo de flúor é responsável pela redução do I.R., concluiu-se que o I.R. no revestimento fluorado do filme óptico variou também de forma gradual. A técnica de polimerização por plasma de CF4+H2 mostrou-se útil para modificar in situ os I.R. da superfíces de guias de ondas e fibras ópticas poliméricas, visando reduzir as perdas e aumentar a velocidade de transmissão de dados.

Abstract:
ABSTRACTPolymer brushes of poly[2-(methacryloyloxy)ethyl]trimethylammonium chloride (PMETAC) and poly(sulfo propyl methacrylate) (PSPM) were synthesized by Atomic Transfer Radical Polymerization from planar and colloidal surfaces. Polymer brush growth was followed by QCMD and the water content determined by combined QCMD and elipsometry. From the water content the percentage of water lost during the brush collapse with the ionic strength could be obtained.Highly charged PSPM brushes were indented by Atomic Force Microscopy at different ionic strengths. The force response was fitted to a phenomenological equation analogous to the equation of state of a compressible fluid. Internal energy and brush compressibility were obtained as a function of ionic strength.Spherical brushes of PMETAC and PSPM display an invariance of the zeta potential with ionic strength in the range from 20 mM to 200 mM NaCl, the zeta potential remains almost constant. This invariance can be explained applying a hairy surface approach.

Abstract:
Diploma thesis deals with ageing process of thin films of Co and Cu on Si substrate, prepared by the IBAD method. The process of film ageing, which depends on time of exposition to the atmosphere at room conditions, was investigated with spectroscopic ellipsometry (VIS+UV) and atomic force microscopy. In case of thin Co films, approximately four days long incubation period was observed. During this time period, a change in the optical parameters of the film occurs without a measurable change of the film topography. Using non-contact atomic force microscopy, a growth of the transitional film in the island growth regime was observed. During the ageing of thin Cu films, two stages of growth of the transitional layer were observed - nucleation stage and growth stage. Both of these time periods of the transitional layer growth show direct logarithmic dependence. Using non-contact atomic force microscopy, the growth of the transitional film was observed. Using atomic force microscopy in non-contact regime, time dependent measurement was done and the process of forming of one monolayer of the transitional layer was documented. Within the diploma thesis, a series of experiments on ultra high vacuum system were performed in order to investigate phase transformation of thin Fe films (22 monolayers) on Cu(100) stabilized by CO absorption. The transformation from fcc phase to bcc phase was induced by Ar+ ion beam bombardment with the ion energy in the range (0.5-4) keV. The process of phase transformation was observed by surface magneto-optic Kerr effect, Auger electron spectroscopy and low energy electron diffraction.

Abstract:
Este trabalho experimental trata da caracterização de filmes sol-gel por elipsometria. A caracterização é um procedimento importante na determinação das propriedades físico-químicas de qualquer material como, por exemplo, filmes finos sol-gel. É possível produzir materiais de natureza diversa (vítreos, cerâmicos e cristalinos) pela técnica sol-gel. A elipsometria, por sua vez, é uma técnica recente na determinação do índice de refração complexo de um material. Os seus fundamentos teóricos tratam da natureza da luz polarizada e sua propagação através de um sistema ótico. No decorrer do trabalho, estes princípios possibilitarão descrever os sistemas óticos utilizados na parte experimental. Os filmes finos têm propriedades óticas e mecânicas que podem diferir bastante daquelas encontradas em certo volume do material. A análise das suas propriedades é feita através das medidas dos seguintes parâmetros: espessura, índice de refração e perfil de tensões. Um dos objetivos deste trabalho foi à observação da evolução das propriedades óticas e mecânicas durante o processo de densificação. Os filmes caracterizados são de sílica (SiO2), depositados sobre três tipos de substratos: vidro comum, sílica fundida, e silício. A caracterização deste material durante o processo de densificação térmica é dividida nas seguintes etapas: a) evolução estrutural através da medida da espessura, b) análise das porosidades pelo espectro do índice de refração, c) determinação das tensões. Como conseqüência, a montagem de um microelipsômetro que mede retardações óticas de filmes finos fez-se necessária e foi realizada durante este trabalho. A sua calibração é possível pela técnica de elipsometria nula. Assim sendo, pode-se especificar o equipamento, bem como aplicá-lo em diversas situações como: a) determinação do estado tênsil ou compreensivo de filmes de CeO2-TiO2; b) determinar tensões em filmes de sílica, c) análise de defeitos em filmes de um óxido misto de SnO2 In2O3(ITO).<br>This is an experimental work about the characterization of thin sol-gel films by ellipsometry. The characterization is an important procedure on determining the physical-chemical properties of many materials such as thin films produced by the sol-gel process. It is possible to produce several kinds of materials (vitreous, ceramic and crist.alline) by using the sol-gel process. The elipsometry, itself is a new technique for the determination of the complex refractive index of a material. Its theoretical principles concern about the nature of the polarized light, and its propagation through an optical system. These principles will be used to describe the optical systems of the experimental procedure along this work. The thin films have optical and mechanical properties that can strongly differ from those found for the material at bulk form. The analwses of these properties is carried out by the measurement of the following parameters: thickness, refractive index and stress profile. One of the goals of this work is to observe the evolution of the optical and mechanical properties during the densification process. The characterized films are of silica (SiO2) deposited on three kinds of substrate: ordinary glass, vitreous silica and single crystal silicon. The characterization of this material during the densification process is divided in t.he following steps: a ) structural evolution by thickness mesurement; b ) porosity study by refractive index spectrum; c) stress determination. As a consequence of this characterization, it was constructed, along the work, a microellipsometer which measures thin film retardation. Its calibration is possible by using the null ellipsometry technique. In this way, the equipment can be specified and applied to different situations such as: a) determination of the stress or compressive state for CeO2-TiO2; b ) stress measurements of silica films; c ) defect st.udy of ITO films SnO2 In2O3.

Abstract:
This thesis deals with guided self-assembly of gold nanoparticles from their colloidal solutions onto silicon substrates and possible employment of nanoparticles for detection of biomolecules. It was found that by adjustment of solution pH and surface chemistry modification by means of electron beam irradiation it is possible to facilitate nanoparticle deposition to patterns with almost single particle precision. Spectroscopic ellipsometry was then employed in analysis of self-assembled layers of nanoparticles and its combination with a theory of effective medium approximation has proven the ability to assess nanoparticle dimensions and volume fractions. By experiments with thiolated oligonucleotides it has been shown that using ellipsometry one can detect even with very subtle changes in nanoparticle environment caused by biomolecules, thus promising its possible use in the field of biodetection.

Abstract:
This diploma thesis deals with methodology of thin film thickness determination using X-ray radiation of silver anode which provides radiation with energy of 2984,3 eV. This energy is twice as high as the standard aluminium radiation which allows a measurement of new photoelectron lines with higher bonding energy and it also provides thanks to the higher photoelectron energy greater information depth. In order to get the right results it was necessary to calibrate the spectrometer Kratos Axis Supra in the silver anode mode first and found out the form of the transmission function. The determination of the thickness of the thin layer was demonstrated by the comparation of the ratio of different photoelectron lines intensities with the theoretical model. For that purpose was specifically used the Si 1s and Si 2p peak bound in the substrate in the Si-Si bonding or in the thin oxid layer in the Si-O bonding. The results show that for thin SiO2/Si film thickness determination is the best to use the intensity ratio of only one photoelectron line. A silver anode however provides greater information depth.
