Book Description
L'objet de ce mémoire est de présenter le travail effectué au cours de cette thèse qui était de caractériser électriquement et de modéliser le transport électrique de trois architectures de transistors MOS pour des filières 50nm et en deçà: CMOS Si à oxyde ultrafin, nMOS Si:C et pMOS SiGe. Afin d'étudier les effets de canaux courts sur ces dispositifs nous avons proposé et/ou optimisé plusieurs procédures d'extraction de paramètres ainsi que plusieurs modèles physiques analytiques décrivant le comportement des principaux paramètres électriques de ce type de transistors aux longueurs de grille décananométriques. Ainsi, une méthode expérimentale complète et un modèle pour la partition du courant de grille ont été validés pour les transistors à oxyde ultrafin. Une optimisation de la méthode Split Cpour les canaux courts a été validée donnant de précieux renseignements sur la mobilité des transistors MOS ultracourts. Un modèle a été validé pour le bruit 1ff des transistors à canal enterré Si Ge sub-O, 11Jm. Toutes ces méthodes nous ont permis de montrer que les transistors à oxyde ultrafins gardaient de très bonne propriétés de transport électrique jusqu'à 30nm de longueur de grille, que les nMOS Si:C était une alternative fiable au fort dopage canal pour contrôler les effets de canaux courts des nMOS sub-O, 1IJm et que les pMOS SiGe avaient un niveau de bruit 1ff plus faible en forte inversion même aux longueurs de grille décanamométriques.

Book Description
Variability is one of the most challenging obstacles for IC design in the nanometer regime. In nanometer technologies, SRAM show an increased sensitivity to process variations due to low-voltage operation requirements, which are aggravated by the strong demand for lower power consumption and cost, while achieving higher performance and density. With the drastic increase in memory densities, lower supply voltages, and higher variations, statistical simulation methodologies become imperative to estimate memory yield and optimize performance and power. This book is an invaluable reference on robust SRAM circuits and statistical design methodologies for researchers and practicing engineers in the field of memory design. It combines state of the art circuit techniques and statistical methodologies to optimize SRAM performance and yield in nanometer technologies. Provides comprehensive review of state-of-the-art, variation-tolerant SRAM circuit techniques; Discusses Impact of device related process variations and how they affect circuit and system performance, from a design point of view; Helps designers optimize memory yield, with practical statistical design methodologies and yield estimation techniques.

Book Description
The aggressive scaling of CMOS technology has inevitably led to vastly increased power dissipation, process variability and reliability degradation, posing tremendous challenges to robust circuit design. To continue the success of integrated circuits, advanced design research must start in parallel with or even ahead of technology development. This new paradigm requires the Predictive Technology Model (PTM) for future technology generations, including nanoscale CMOS and post-silicon devices. This paper presents a comprehensive set of predictive modeling developments. Starting from the PTM of traditional CMOS devices, it extends to CMOS alternatives at the end of the silicon roadmap, such as strained Si, high-k/metal gate, and FinFET devices. The impact of process variation and the aging effect is further captured by modeling the device parameters under the influence. Beyond the silicon roadmap, the PTM outreaches to revolutionary devices, especially carbon-based transistor and interconnect, in order to support explorative design research. Overall, these predictive device models enable early stage design exploration with increasing technology diversity, helping shed light on the opportunities and challenges in the nanoelectronics era.

Book Description
This book on solid state physics has been written with an emphasis on recent developments in quantum many-body physics approaches. It starts by covering the classical theory of solids and electrons and describes how this classical model has failed. The authors then present the quantum mechanical model of electrons in a lattice and they also discuss the theory of conductivity. Extensive reviews on the topic are provided in a compact manner so that any non-specialist can follow from the beginning.The authors cover the system of magnetism in a similar way and various problems in magnetic materials are discussed. The book also discusses the Ising chain, the Heisenberg model, the Kondo effect and superconductivity, amongst other relevant topics.In the final chapter, the authors present some works related to contemporary research topics, such as quantum entanglement in many-body systems and quantum simulations. They also include a short review of some of the possible applications of solid state quantum information in biological systems.

Book Description
This book provides comprehensive coverage of the dependability challenges in today's advanced computing systems. It is an in-depth discussion of all the technological and design-level techniques that may be used to overcome these issues and analyzes various dependability-assessment methods. The impact of individual application scenarios on the definition of challenges and solutions is considered so that the designer can clearly assess the problems and adjust the solution based on the specifications in question. The book is composed of three sections, beginning with an introduction to current dependability challenges arising in complex computing systems implemented with nanoscale technologies, and of the effect of the application scenario. The second section details all the fault-tolerance techniques that are applicable in the manufacture of reliable advanced computing devices. Different levels, from technology-level fault avoidance to the use of error correcting codes and system-level checkpointing are introduced and explained as applicable to the different application scenario requirements. Finally the third section proposes a roadmap of future trends in and perspectives on the dependability and manufacturability of advanced computing systems from the special point of view of industrial stakeholders. Dependable Multicore Architectures at Nanoscale showcases the original ideas and concepts introduced into the field of nanoscale manufacturing and systems reliability over nearly four years of work within COST Action IC1103 MEDIAN, a think-tank with participants from 27 countries. Academic researchers and graduate students working in multi-core computer systems and their manufacture will find this book of interest as will industrial design and manufacturing engineers working in VLSI companies.

Book Description
Matching Properties of Deep Sub-Micron MOS Transistors examines this interesting phenomenon. Microscopic fluctuations cause stochastic parameter fluctuations that affect the accuracy of the MOSFET. For analog circuits this determines the trade-off between speed, power, accuracy and yield. Furthermore, due to the down-scaling of device dimensions, transistor mismatch has an increasing impact on digital circuits. The matching properties of MOSFETs are studied at several levels of abstraction: A simple and physics-based model is presented that accurately describes the mismatch in the drain current. The model is illustrated by dimensioning the unit current cell of a current-steering D/A converter. The most commonly used methods to extract the matching properties of a technology are bench-marked with respect to model accuracy, measurement accuracy and speed, and physical contents of the extracted parameters. The physical origins of microscopic fluctuations and how they affect MOSFET operation are investigated. This leads to a refinement of the generally applied 1/area law. In addition, the analysis of simple transistor models highlights the physical mechanisms that dominate the fluctuations in the drain current and transconductance. The impact of process parameters on the matching properties is discussed. The impact of gate line-edge roughness is investigated, which is considered to be one of the roadblocks to the further down-scaling of the MOS transistor. Matching Properties of Deep Sub-Micron MOS Transistors is aimed at device physicists, characterization engineers, technology designers, circuit designers, or anybody else interested in the stochastic properties of the MOSFET.
