Full textCurrent scaling trend in microelectronic involves the introduction of metals and high-k dielectrics in MOS transistors and MIM capacitors manufacturing in order to maintain their electrical performances. Nevertheless, the integration of these materials must deal with some physical phenomena localized at the metal/insulator interface that can degrade the devices performances. As a result, the choice of materials cannot be done on the simple consideration of their intrinsic properties and necessarily passes by a careful analysis of the properties of the interface formed. We present in this study fine characterizations of the TiN/Ta2O5 interface properties as well as their impact on the performances of the MIM 5fF. Mm-2 capacitor. We first present the impact of interfaces roughness on leakage-current characteristics of MIM capacitors. “In situ” simulations of the electric field in the device indicate that each interface topography can lead to asymmetrical MIM electrical behavior. Next, our analysis treats the fundamental properties which control metal layers work function. This study requires the use of a local probe (KFM) which allows to characterize the impact of metal films crystallography on work function. Finally, the effect on the barrier height of the TiN/Ta2O5 interface chemistry is presented. This study, carried out by X-ray and UV-ray photoelectrons spectroscopy, provides the complete band diagram of the TiN/Ta2O5/Si MIS structure. We report here large shifts of the vacuum level induced by dipoles at both the Si/Ta2O5 and Ta2O5/TiN interfaces

Full textGenerally microsystems require to be inserted in an environment perfectly controlled in order to allow an optimum functioning process (vacuum for example when the quality factor must be high) or to be able to connect its exit characteristics to the operating conditions. It is thus important to be able to place them in a perfectly adapted packaging of protection. Before that, the device must be cut out in the silicon substrate. This cutting step is critical because it requires the use of a fluid jet on surface which can involve the partial or complete damage device or cause the sticking effect of microdevices on the substrate. We imagined an original film transfer process on the device in order to ensure the MEMS protection during this cutting step. This process uses the transfer technology, namely that micro-caps are elaborate on a specific substrate then separated of this substrate to protect to micro-structures on the final substrate. More largely, this universal process makes it possible to carry out a very great choice of microdevices (Pirani gauges for example). Thus, this process was fully qualified for packaging applications then extended to microstructures transfer

Resumo: Os fenômenos eletrostáticos e suas consequências são familiares para a maioria das pessoas, mas o conhecimento sobre este tópico ainda é bastante empírico. Persistem grandes dificuldades na correlação de idéias fundamentais da teoria atômico-molecular com observações experimentais da eletrostática de materiais isolantes. A hipótese explorada nessa tese é: a atmosfera é uma fonte de cargas elétricas em isolantes, devido à partição de grupos OH- e H+ associados à adsorção de água. Logo, interações específicas entre íons presentes na água e sólidos isolantes contribuem para os padrões de cargas. Neste trabalho foram analisados padrões eletrostáticos em uma superfície de sílica recoberta por eletrodos de ouro produzidos por técnicas microlitográficas e partículas amorfas de fosfato de alumínio e sílica de Stöber utilizando a microscopia de força Kelvin (KFM) sob umidade relativa controlada. Os potenciais elétricos sobre a superfície de sílica dependem fortemente da umidade relativa, bem como da polarização dos eletrodos de ouro. A formação e dissipação dos padrões eletrostáticos são mais rápidas sob altas umidades. Já em baixas umidades a preservação dos potenciais elétricos é mais efetiva. Os potenciais elétricos das partículas de sílica e fosfato de alumínio são fortemente influenciados pela umidade relativa, sendo alterados mesmo em um ambiente completamente isolado eletricamente e aterrado. Os potenciais são modificados por eventos de adsorção e dessorção de água: sílica de Stöber torna-se mais negativa com o aumento da umidade, enquanto o fosfato de alumínio torna-se menos negativo, na ausência de qualquer ação de indução por um campo elétrico. Os resultados mostraram que a adsorção de água modifica os padrões de cargas de superfícies inorgânicas em escala nanométrica e que a eletroneutralidade não é uma característica geral de materiais isolantes. Neste trabalho também foram examinadas propriedades mecânicas de rigidez e adesão em nanoescala de partículas de fosfato de alumínio e dióxido de titânio, utilizando a microscopia de força pulsada digital (DPFM). As partículas apresentam uma grande heterogeneidade mecânica, mostrando domínios bastante diferenciados entre si. A nanoindentação da ponteira do AFM sobre as partículas mostrou que o dióxido de titânio apresenta maiores valores de rigidez, módulo de Young, força e energia de adesão e de histerese na deformação de suas superfícies.
Abstract: Electrostatic charging is familiar to most persons but knowledge on this topic is still rather empiric, mainly because fundamental ideas on the structure of matter are not well connected to the phenomenology of insulator charging. This thesis explores the following hypothesis: the atmosphere is as an electric charge reservoir for insulators, due to the partition of OH- and H+ groups associated to water adsorption. Thus, specific interactions between ions of adsorbed layers of water and insulating solids contribute to charge patterning. In this work, electrostatic patterning was examined in a silica surface partially covered with sets of interdigitated gold electrodes produced by microlithography techniques and also in aluminum phosphate and Stöber silica amorphous particles, using Kelvin force microscopy (KFM) under controlled relative humidity. Electric potentials acquired from the silica surface depend largely on the relative humidity as well as on the applied potentials at the gold electrodes. Pattern formation and dissipation are much faster under high relative humidity while the charged or discharged silica states are both more stable at low humidity. The electric potential measured along the surface of amorphous particles changes with relative humidity within an electrically shielded and grounded environment. Thus, water adsorption and desorption modify charge status of these particles: Stöber silica surface becomes more negative at higher humidity while aluminum phosphate becomes less negative, without any external electric potential or inductive input. These results show that water adsorption modifies charge status of inorganic surfaces and that electroneutrality is not a widespread characteristic of insulating materials. Another section of the thesis describes local nanomechanical stiffness and adhesion properties for aluminum phosphate and titanium dioxide particles, using digital pulsed force microscopy (DPFM). Aluminum phosphate and titanium dioxide particle domains present a large degree of heterogeneity. Aluminum phosphate particles are softer materials than titanium dioxide, undergoing greater nanoindentation of the AFM tip. On the other hand, titanium dioxide particle surfaces present larger stiffness, Young modulus, tipadhesion force, energy dissipated by hysteresis and detachment energy than aluminum phosphate particles.

Full textThis thesis addresses the characterization of individual doped semiconductors microand nanowires by photoemission electron microscopy (XPEEM) and near field techniques : Kelvin probe force microscopy (KFM) and scanning capacitance microscopy. The aim of this study is to evaluate the benefits of contactless surface methods, thanks to local work function and core level binding energy measurements, for the study of phenomena linked to doping in such objects, like for example axial uniformity. First, we highlight the importance of sample preparation required for these techniques: wires transfer methods, substrate/wire match, and preanalysis characterization influence. Then we present two case studies addressing technological issues: Si doped gallium nitride microwires (2μm diameter) for solid state lighting, and p-n junction nanowires (100 nm diameter) for low power microelectronics. In the first case, we have performed SCM for quick identification of n doping axial heterogeneity, then performed spectroscopic XPEEM using synchrotron radiation to, first, estimate local work function and surface band bending, then clarify surface silicon incorporation highlighting growth process influence over intentional (si on Ga sites) and unintentional doping (si on nitrogen vacancy). Complementary measurements on both axial and radial section of wires have been led by Auger microscopy and ToF-SIMS, highlighting silicon incorporation preferentially at the surface of the microwires. Regarding p-n junctions, after partial removal of surface oxide, we have linked results obtained independently by KFM and XPEEM. Both methods highlighted a weak local work function difference between n-doped and p-doped part, partly explained by Fermi level pinning induced by surface states

Full textThis work is dedicated to the localized synthesis of a controlled number of Si nanocrystals into SiO2 layer, by two ion implantation methods. On the one hand, the ultra low energy ion implantation followed by thermal annealing (ULE-II) leads to create a two dimensional array of nanocrystals ; On the other hand, the original SM-ULE-II method where ULE-II is performed through a stencil mask leads to fabricate localized areas of Si nanocrystals while controlling their number. Characterizations by SEM, AFM, EFTEM, photoluminescence spectroscopy allow studying the structural properties of the nanocrystals (size, density, shape, localization into the oxide, implanted areas characteristics,. . ). Then, a reduced number of nanocrystals elaborated by ULE-II (108 to 50) or SM-ULE-II is addressed by a micro to nanometer MOS capacitor. Room temperature I-V and I-t measurements exhibit collective charging effects (large number of nanocrystals addressed or connected nanocrystals) and discrete charging effects (a few number of nanocrystals or nanocrystals elaborated by SM-ULE-II and oxidized). An electrical model relates the electrical and structural properties. I-V characterizations realized at low temperature and KFM measurements confirm charge storage essentially into nanocrystals. C-V curves prove that nanocrystals are attractive to non volatile memory applications, and using transparent electrode (ZnO or ITO), nanocrystals can be optically excited and electrically addressed in order to create electro optical components

Taking KMFA as the center of the circle within 5 kilometers radius around, the natural landscapes of mountains, ocean, rivers, harbor and ponds create an attractive and natural scenery which consists of unique local characteristics, and brilliant recreational resources. It is a touchable and enjoyable "living museum." For this sake, the recreational functions of KMFA must not be limited in the conservative and traditional buildings. Therefore, more creative concepts of extensive space and boundless surrounding resources are needed. Constructional and rigid buildings must be used as public space increasing its extra values, competitiveness and sustainable developments of KMFA. According to research points of view, there are very few study results from "the combination of KMFA and the surrounding recreational resources." This is a study to discover it; in this study, the concept of 'strategic pattern analysis’ in which Analysis Of Operational Strategies were proposed by national scholar Si tu da xian(1995)is applied in the analysis of the feasibility of combination of KMFA and the surrounding recreational resources. By applying the 'strategic pattern analysis', six parts, the product range and features, differentiating the target markets, levels of vertical integration, relative scales, geographical coverage and competitiveness strength, have been introduced, verified and examined in order to find out a useful, applicable way for KMFA.Moreover, finding the classics masterpieces collected by KFAM corresponding to the recreational resources in City Nei Wei Pi KFAM surroundings and as well as to the city cultural symbols which are discussed, analyzed, described and explained in order to enhance the citizens' understanding towards Kaohsiung City, increase the recreational motivation and recall the passion to the local cultures. The sensibility and vitality of Kaohsiung City then can be expected.

Nowadays people can watch movies in different devices because of technology advancement and smartphone popularity. This phenomenon also brings some opportunities to film or video industries to provide video on different platforms. New business models become an important issue. Unlike other film festivals, Kaohsiung Film Festival (KFF) not only provided movies in theaters, but also launched the “KFF Cloud Cinema” app (both iOS & Android systems) in 2014. In this app, pay-per-view (PPV) & video on demand (VOD) services was provided to the audiences. This app attracted over 22,000 downloads and the entries received over 500,000 clicks. KFF 2014 not only created the highest participation rate in Taiwan’s film festival history, but also set a new model for Taiwan’s film festival development. This qualitative study was designed to investigate the present and future feasible business models and user acceptance for short-film-oriented film festivals apps. KFF Cloud Cinema app was adopted as an example. Relevant roles like the festival curator, contestants and audiences were interviewed to gather research data. Total nine respondents from the above three roles were interviewed, and in-depth interview was adopted. A semi-structured interview guide was developed based on the cognitive attributes of innovation, innovativeness of adopters, and priorities of innovation acceptance in the diffusion of innovations theory. The results shown that: (a) KFF Cloud Cinema was designed to adopt a business model of lower profit for promoting short films and encouraging users to pay and watch those films online; (b) instead of the profit sharing model commonly practiced by streaming video platforms, KFF Cloud Cinema charged the broadcast fee to license movie broadcast during the festival period, which is the same licensing model as in traditional film festivals; and (c) both the KFF Cloud Cinema users and KFF entrants had high acceptance of this innovation featuring a complement between the virtual film festival and the physical film festival.
