Îïèñàíèå: The main goal of this book is to review at the nano and atomic scale the very complex scientific issues that pertain to the use of advanced high dielectric constant (high-k) materials in next generation semiconductor devices. One of the key obstacles to integrate this novel class of materials into Si nano-technology are the electronic defects in high-k dielectrics. It has been established that defects do exist in high-k dielectrics and they play an important role in device operation. The unique feature of this book is a special focus on the important issue of defects. The subject is covered from various angles, including silicon technology, processing aspects, materials properties, electrical defects, microstructural studies, and theory. The authors who have contributed to the book represents a diverse group of leading scientists from academic, industrial and governmental labs worldwide who bring a broad array of backgrounds (basic and applied physics, chemistry, electrical engineering, surface science, and materials science). The contributions to this book are accessible to both expert scientists and engineers who need to keep up with leading edge research, and newcomers to the field who wish to learn more about the exciting basic and applied research issues relevant to next generation device technology.
Îïèñàíèå: Physics of Semiconductor Devices covers both basic classic topics such as energy band theory and the gradual-channel model of the MOSFET as well as advanced concepts and devices such as MOSFET short-channel effects, low-dimensional devices and single-electron transistors. Concepts are introduced to the reader in a simple way, often using comparisons to everyday-life experiences such as simple fluid mechanics. They are then explained in depth and mathematical developments are fully described. Physics of Semiconductor Devices contains a list of problems that can be used as homework assignments or can be solved in class to exemplify the theory. Many of these problems make use of Matlab and are aimed at illustrating theoretical concepts in a graphical manner.

Îïèñàíèå: The book details many of the key issues associated with the scaling to nano-dimensions of silicon-on-insulator structures. Some papers offer new insight particularly at the device/circuit interface as appropriate for SOI which is fast becoming a mainstream technology. One of the key issues concerns mobility degradation in SOI films less than about 5nm. The advantages of combining scaled SOI devices with high permittivity (k) dielectric indicates that potential solutions are indeed available down to the 22nm node even with 5nm SOI films. A further key issue and potential ‘show stopper’ for SOI CMOS is highlighted in a number of invited and contributed papers addressing atomistic level effects. Results are presented for Monte Carlo and drift/diffusion modelling together with device compact models and circuit level simulation and this provided for a broad exposure of the problems from intrinsic physics to the circuit level. The scaling to nano-dimensions takes the technology into the realms of quantum effects and a number of papers addressed this aspect from both the technological and physics aspects. The scope of potential applications for quantum dots, quantum wires and nanotubes are considered. The use of semiconductor materials other than Si, on insulator, is featured in some sections of the book. The potential of III/V, Ge and other materials to facilitate continuation down the roadmap is illustrated by a review of the state-of-the-art.

Îïèñàíèå: Physics of Semiconductor Devices is a textbook aimed at college undergraduate and graduate teaching. It covers both basic classic topics such as energy band theory and the gradual-channel model of the MOSFET as well as advanced concepts and devices such as MOSFET short-channel effects, low-dimensional devices and single-electron transistors. As a prerequisite, this text requires mathematics through differential equations and modern physics where students are introduced to quantum mechanics. Concepts are introduced to the reader in a simple way, often using comparisons to everyday-life experiences such as simple fluid mechanics. They are then explained in depth and mathematical developments are fully described. Physics of Semiconductor Devices contains a list of problems that can be used as homework assignments or can be solved in class to exemplify the theory. Many of these problems make use of Matlab and are aimed at illustrating theoretical concepts in a graphical manner. A series of these Matlab problems is based on a simple finite-element solution of semiconductor equations. These yield the exact solution to equations that have no analytical solutions and are usually solved using approximations, such as the depletion approximation. The exact numerical solution can then be graphically compared to the solution using the approximation. The different chapters of Physics of Semiconductor Devices cover the following material: Energy Band Theory. Theory of Electrical Conduction. Generation/Recombination Phenomena. The PN Junction Diode. Metal-semiconductor contacts. JFET and MESFET. The MOS Transistor. The Bipolar Transistor. Heterojunction Devices. Quantum-Effect Devices. Semiconductor Processing.
