Nanoscale CMOS
Author: Francis Balestra
Publisher: John Wiley & Sons
ISBN: 1118622472
Category : Technology & Engineering
Languages : en
Pages : 518
Book Description
This book provides a comprehensive review of the state-of-the-art in the development of new and innovative materials, and of advanced modeling and characterization methods for nanoscale CMOS devices. Leading global industry bodies including the International Technology Roadmap for Semiconductors (ITRS) have created a forecast of performance improvements that will be delivered in the foreseeable future – in the form of a roadmap that will lead to a substantial enlargement in the number of materials, technologies and device architectures used in CMOS devices. This book addresses the field of materials development, which has been the subject of a major research drive aimed at finding new ways to enhance the performance of semiconductor technologies. It covers three areas that will each have a dramatic impact on the development of future CMOS devices: global and local strained and alternative materials for high speed channels on bulk substrate and insulator; very low access resistance; and various high dielectric constant gate stacks for power scaling. The book also provides information on the most appropriate modeling and simulation methods for electrical properties of advanced MOSFETs, including ballistic transport, gate leakage, atomistic simulation, and compact models for single and multi-gate devices, nanowire and carbon-based FETs. Finally, the book presents an in-depth investigation of the main nanocharacterization techniques that can be used for an accurate determination of transport parameters, interface defects, channel strain as well as RF properties, including capacitance-conductance, improved split C-V, magnetoresistance, charge pumping, low frequency noise, and Raman spectroscopy.

Introduction to Simulations of Semiconductor Lasers
Author: Marek Wartak
Publisher: CRC Press
ISBN: 1003860982
Category : Technology & Engineering
Languages : en
Pages : 364
Book Description
Simulations play an increasingly important role not only in scientific research but also in engineering developments. Introduction to Simulations of Semiconductor Lasers introduces senior undergraduates to the design of semiconductor lasers and their simulations. The book begins with explaining the physics and fundamental characteristics behind semiconductor lasers and their applications. It presumes little prior knowledge, such that only a familiarity with the basics of electromagnetism and quantum mechanics is required. The book transitions from textbook explanations, equations, and formulas to ready-to-run numeric codes that enable the visualization of concepts and simulation studies. Multiple chapters are supported by MATLAB code which can be accessed by the students. These are ready-to-run, but they can be modified to simulate other structures if desired. Providing a unified treatment of the fundamental principles and physics of semiconductors and semiconductor lasers, Introduction to Simulations of Semiconductor Lasers is an accessible, practical guide for advanced undergraduate students of Physics, particularly for courses in laser physics. Key Features: A unified treatment of fundamental principles Explanations of the fundamental physics of semiconductor Explanations of the operation of semiconductor lasers An historical overview of the subject

The Non-Equilibrium Green's Function Method for Nanoscale Device Simulation
Author: Mahdi Pourfath
Publisher: Springer
ISBN: 370911800X
Category : Technology & Engineering
Languages : en
Pages : 268
Book Description
For modeling the transport of carriers in nanoscale devices, a Green-function formalism is the most accurate approach. Due to the complexity of the formalism, one should have a deep understanding of the underlying principles and use smart approximations and numerical methods for solving the kinetic equations at a reasonable computational time. In this book the required concepts from quantum and statistical mechanics and numerical methods for calculating Green functions are presented. The Green function is studied in detail for systems both under equilibrium and under nonequilibrium conditions. Because the formalism enables rigorous modeling of different scattering mechanisms in terms of self-energies, but an exact evaluation of self-energies for realistic systems is not possible, their approximation and inclusion in the quantum kinetic equations of the Green functions are elaborated. All the elements of the kinetic equations, which are the device Hamiltonian, contact self-energies and scattering self-energies, are examined and efficient methods for their evaluation are explained. Finally, the application of these methods to study novel electronic devices such as nanotubes, graphene, Si-nanowires and low-dimensional thermoelectric devices and photodetectors are discussed.

Protecting Chips Against Hold Time Violations Due to Variability
Author: Gustavo Neuberger
Publisher: Springer Science & Business Media
ISBN: 9400724276
Category : Technology & Engineering
Languages : en
Pages : 114
Book Description
With the development of Very-Deep Sub-Micron technologies, process variability is becoming increasingly important and is a very important issue in the design of complex circuits. Process variability is the statistical variation of process parameters, meaning that these parameters do not have always the same value, but become a random variable, with a given mean value and standard deviation. This effect can lead to several issues in digital circuit design. The logical consequence of this parameter variation is that circuit characteristics, as delay and power, also become random variables. Because of the delay variability, not all circuits will now have the same performance, but some will be faster and some slower. However, the slowest circuits may be so slow that they will not be appropriate for sale. On the other hand, the fastest circuits that could be sold for a higher price can be very leaky, and also not very appropriate for sale. A main consequence of power variability is that the power consumption of some circuits will be different than expected, reducing reliability, average life expectancy and warranty of products. Sometimes the circuits will not work at all, due to reasons associated with process variations. At the end, these effects result in lower yield and lower profitability. To understand these effects, it is necessary to study the consequences of variability in several aspects of circuit design, like logic gates, storage elements, clock distribution, and any other that can be affected by process variations. The main focus of this book will be storage elements.

High-dimensional Nonlinear Diffusion Stochastic Processes

ISBN: 9789812810540
Category : Mathematics
Languages : en
Pages : 332
Book Description
Annotation This book is one of the first few devoted to high-dimensional diffusion stochastic processes with nonlinear coefficients. These processes are closely associated with large systems of Ito's stochastic differential equations and with discretized-in-the-parameter versions of Ito's stochastic differential equations that are nonlocally dependent on the parameter. The latter models include Ito's stochastic integro-differential, partial differential and partial integro-differential equations.The book presents the new analytical treatment which can serve as the basis of a combined, analytical -- numerical approach to greater computational efficiency. Some examples of the modelling of noise in semiconductor devices are provided
