Book excerpt: Ce travail de thèse concerne la caractérisation de transistors 1 bipolaires à hétérojonctions Si/SiGe (TBH SiGe). Mon rôle a été d'étudier certaines spécificités du comportement électrique du TBH SiGe liées à la présence d'une base épitaxiée, et de mettre ainsi en évidence ce qui apparaissait comme atypique dans le fonctionnement de ce dispositif par rapport au transistor bipolaire silicium actuel. Dans ce contexte, nous avons porté une attention particulière à l'étude du courant de fuite de la jonction base-collecteur et à l'étude de la recombinaison en base neutre. Nous nous sommes attachés à corréler nos mesures électriques à la technologie. Nous avons ainsi contribué a l'amélioration du nettoyage avant l'épitaxie et de la qualité cristalline du matériau SiGe. Nos analyses électriques de la recombinaison en base neutre nous : ont permis de mettre au point une méthode d'extraction de la durée de vie apparente des électrons dans la base neutre. Cette méthode apporte les 1 éléments de base pour formuler une modélisation du courant de recombinaison en base neutre qui peut être intégrée dans un modèle compact de TBH (utilisable pour la simulation de circuits). Enfin, nous avons fourni les grandeurs électriques de TBH SiGe pour évaluer par la simulation de circuits le gain en performances apporté par ce dispositif pour des applications radiofréquences.

This book was released on 1998 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail concerne les Transistors Bipolaires à Hétérojonctions (TBH) Si/SiGe. Nous présentons comment des TBH ont été intégrés dans une filière Bi CM OS du Centre Commun CNET -SGS Thomson. Au préalable, afin de définir l'architecture la mieux adaptée au contexte et de tirer le meilleur parti possible de l'utilisation de SiGe, les différents paramètres (profil de germanium, position du bore par rapport à la zone SiGe...) influençant le fonctionnement des TBH ont été étudiés, en particulier grâce à la mise en place d'un environnement de simulation adapté aux hétéro structures. Les contraintes technologiques et leurs conséquences sur les dispositifs ont été prises en compte. Les premiers résultats ont permis de mettre en évidence un certain nombre de problèmes technologiques que nous avons résolus. La caractérisation électrique a montré une nette amélioration des performances et a précisé les atouts réels de SiGe dans un contexte BiCMOS pourtant initialement jugé peu favorable. Nous avons aussi vérifié que les transistors MOS n'étaient pas perturbés. Ce travail démontre donc la faisabilité de l'intégration des TBH dans une filière BiCMOS et offre des perspectives pour l'évolution des structures.
Book Synopsis Développement et étude de transistors bipolaires à hétérojonctions Si/SiGe:C pour les technologies BiCMOS millimétriques by : Boris Geynet
Download or read book Développement et étude de transistors bipolaires à hétérojonctions Si/SiGe:C pour les technologies BiCMOS millimétriques written by Boris Geynet and published by . This book was released on 2008 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les transistors bipolaires à hétérojonctions (TBH) Si/SiGe:C disponibles aujourd'hui dans les technologies BiCMOS atteignent des fréquences de coupure fT et fmax supérieures à 200GHz. Cela leur permet d'adresser des applications dans le domaine millimétrique jusqu'à 100GHz telles que les radars anticollision pour l'automobile et les communications optiques et sans fil à haut débit. Cette thèse a pour objet le développement et l'étude de TBH Si/SiGe:C pour les technologies BiCMOS millimétriques. Après un rappel des principes de fonctionnement du transistor bipolaire, nous montrons les méthodes de fabrication, caractérisation et modélisation des dispositifs de dernière génération. Les architectures choisies et les performances obtenues par les principaux acteurs du marché sont détaillées. Nous présentons ensuite des études menées pour le développement de la technologie BiCMOS9MW de STMicroelectronics. Une version faible-coût du TBH rapide ainsi qu'un dispositif haute-tension compatible avec la technologie sont présentés et les résultats à l'état de l'art obtenus sur les deux architectures sont montrés. Nous étudions également l'impact des variations des paramètres technologiques et de la géométrie des dispositifs sur les principales caractéristiques de ces composants. La dernière partie de ce travail de thèse est consacrée au développement de nouvelles solutions technologiques afin d'améliorer encore la fréquence de transition des TBH Si/SiGe:C. Un optimisation du profil vertical du TBH a pu être réalisée grâce au développement d'un nouveau module de collecteur utilisant une épitaxie sélective et la réduction du budget thermique vu par les dispositifs durant leur fabrication. Cette dernière étude a permis d'atteindre une fréquence de transition fT· supérieure à 400GHz à température ambiante, ce qui représente la meilleure performance obtenue à ce jour pour un transistor en technologie silicium.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
Book Synopsis Charge-Based MOS Transistor Modeling by : Christian C. Enz
Download or read book Charge-Based MOS Transistor Modeling written by Christian C. Enz and published by John Wiley & Sons. This book was released on 2006-08-14 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern, large-scale analog integrated circuits (ICs) are essentially composed of metal-oxide semiconductor (MOS) transistors and their interconnections. As technology scales down to deep sub-micron dimensions and supply voltage decreases to reduce power consumption, these complex analog circuits are even more dependent on the exact behavior of each transistor. High-performance analog circuit design requires a very detailed model of the transistor, describing accurately its static and dynamic behaviors, its noise and matching limitations and its temperature variations. The charge-based EKV (Enz-Krummenacher-Vittoz) MOS transistor model for IC design has been developed to provide a clear understanding of the device properties, without the use of complicated equations. All the static, dynamic, noise, non-quasi-static models are completely described in terms of the inversion charge at the source and at the drain taking advantage of the symmetry of the device. Thanks to its hierarchical structure, the model offers several coherent description levels, from basic hand calculation equations to complete computer simulation model. It is also compact, with a minimum number of process-dependant device parameters. Written by its developers, this book provides a comprehensive treatment of the EKV charge-based model of the MOS transistor for the design and simulation of low-power analog and RF ICs. Clearly split into three parts, the authors systematically examine: the basic long-channel intrinsic charge-based model, including all the fundamental aspects of the EKV MOST model such as the basic large-signal static model, the noise model, and a discussion of temperature effects and matching properties; the extended charge-based model, presenting important information for understanding the operation of deep-submicron devices; the high-frequency model, setting out a complete MOS transistor model required for designing RF CMOS integrated circuits. Practising engineers and circuit designers in the semiconductor device and electronics systems industry will find this book a valuable guide to the modelling of MOS transistors for integrated circuits. It is also a useful reference for advanced students in electrical and computer engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Circuit simulation is essential in integrated circuit design, and the accuracy of circuit simulation depends on the accuracy of the transistor model. BSIM3v3 (BSIM for Berkeley Short-channel IGFET Model) has been selected as the first MOSFET model for standardization by the Compact Model Council, a consortium of leading companies in semiconductor and design tools. In the next few years, many fabless and integrated semiconductor companies are expected to switch from dozens of other MOSFET models to BSIM3. This will require many device engineers and most circuit designers to learn the basics of BSIM3. MOSFET Modeling & BSIM3 User's Guide explains the detailed physical effects that are important in modeling MOSFETs, and presents the derivations of compact model expressions so that users can understand the physical meaning of the model equations and parameters. It is the first book devoted to BSIM3. It treats the BSIM3 model in detail as used in digital, analog and RF circuit design. It covers the complete set of models, i.e., I-V model, capacitance model, noise model, parasitics model, substrate current model, temperature effect model and non quasi-static model. MOSFET Modeling & BSIM3 User's Guide not only addresses the device modeling issues but also provides a user's guide to the device or circuit design engineers who use the BSIM3 model in digital/analog circuit design, RF modeling, statistical modeling, and technology prediction. This book is written for circuit designers and device engineers, as well as device scientists worldwide. It is also suitable as a reference for graduate courses and courses in circuit design or device modelling. Furthermore, it can be used as a textbook for industry courses devoted to BSIM3. MOSFET Modeling & BSIM3 User's Guide is comprehensive and practical. It is balanced between the background information and advanced discussion of BSIM3. It is helpful to experts and students alike.

Book Synopsis Mosfet Modeling For Circuit Analysis And Design by : Carlos Galup-montoro
Download or read book Mosfet Modeling For Circuit Analysis And Design written by Carlos Galup-montoro and published by World Scientific. This book was released on 2007-02-27 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book dedicated to the next generation of MOSFET models. Addressed to circuit designers with an in-depth treatment that appeals to device specialists, the book presents a fresh view of compact modeling, having completely abandoned the regional modeling approach.Both an overview of the basic physics theory required to build compact MOSFET models and a unified treatment of inversion-charge and surface-potential models are provided. The needs of digital, analog and RF designers as regards the availability of simple equations for circuit designs are taken into account. Compact expressions for hand analysis or for automatic synthesis, valid in all operating regions, are presented throughout the book. All the main expressions for computer simulation used in the new generation compact models are derived.Since designers in advanced technologies are increasingly concerned with fluctuations, the modeling of fluctuations is strongly emphasized. A unified approach for both space (matching) and time (noise) fluctuations is introduced.
Book Synopsis The Physics and Modeling of Mosfets by : Mitiko Miura-Mattausch
Download or read book The Physics and Modeling of Mosfets written by Mitiko Miura-Mattausch and published by World Scientific. This book was released on 2008 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a timely description of the latest compact MOS transistor models for circuit simulation. The first generation BSIM3 and BSIM4 models that have dominated circuit simulation in the last decade are no longer capable of characterizing all the important features of modern sub-100nm MOS transistors. This book discusses the second generation MOS transistor models that are now in urgent demand and being brought into the initial phase of manufacturing applications. It considers how the models are to include the complete drift-diffusion theory using the surface potential variable in the MOS transistor channel in order to give one characterization equation.
