| dc.description.abstract | This volume originates from the lectures on Solid-State Electronics and Microelectronics
that I have been giving since 1978 at the School of Engineering of the
University of Bologna. Its scope is to provide the reader with a book that, starting
from the elementary principles of classical mechanics and electromagnetism,
introduces the concepts of quantum mechanics and solid-state theory, and describes
the basic physics of semiconductors including the hierarchy of transport models,
ending up with the standard mathematical model of semiconductor devices and the
analysis of the behavior of basic devices. The ambition of the work has been to
write a book, self contained as far as possible, that would be useful for both students
and researchers; to this purpose, a strong effort has been made to elucidate physical
concepts, mathematical derivations, and approximation levels, without being
verbose.
The book is divided into eight parts. Part I deals with analytical mechanics and
electromagnetism; purposedly, the material is not given in the form of a resumé:
quantum-mechanics and solid-state theory’s concepts are so richly intertwined with
the classical ones that presenting the latter in an abridged form may make the reading
unwieldy and the connections more difficult to establish. Part II provides the
introductory concepts of statistical mechanics and quantum mechanics, followed
by the description of the general methods of quantum mechanics. The problem of
bridging the classical concepts with the quantum ones is first tackled using the historical
perspective, covering the years from 1900 to 1926. The type of statistical
description necessary for describing the experiments, and the connection with the
limiting case of the same experiments involving massive bodies, is related to the
properties of the doubly-stochastic matrices. Part III illustrates a number of applications
of the Schrödinger equation: elementary cases, solutions by factorization, and
time-dependent perturbation theory. Part IV analyzes the properties of systems of
particles, with special attention to those made of identical particles, and the methods
for separating the equations. The concepts above are applied in PartV to the analysis
of periodic structures, with emphasis to crystals of the cubic type and to silicon in
particular, which, since the late 1960s, has been and still is the most important material
for the fabrication of integrated circuits. Part VI illustrates the single-electron
dynamics in a periodic structure and derives the semiclassical Boltzmann Transport Equation; from the latter, the hydrodynamic and drift-diffusion models of semiconductor
devices are obtained using the moments expansion. The drift-diffusion model
is used in Part VII to work out analytically the electrical characteristics for the basic
devices of the bipolar and MOS type. Finally, Part VIII presents a collection of
items which, although important per se, are not in the book’s mainstream: some of
the fabrication-process steps of integrated circuits (thermal diffusion, thermal oxidation,
layer deposition, epitaxy), and methods for measuring the semiconductor
parameters. | en_US |
