Since the beginning of semiconductor era in microelectronics the methodology of reliability assessment became a well established area. In most cases the reliability assessment involves statistical methods for safe operating area and long term re- ability parameters at the development of semiconductor processes, components and systems. At the same time in case of catastrophic failures at any development phase the major practical method is failure analysis (FA). However FA is mainly dealing with detection of consequences of some irreversible event that already happened. This book is focused on the most important and the less summarized reliability aspects. Among them: catastrophic failures, impact of local structural inhomo- neities, major principles of physical limitation of safe-operating area (SOA), physical mechanisms of the current instability, filamentation and conductivity modulation in particular device types and architectures. Specifically, the similar principles and regularities are discussed for elect- static discharge (ESD) protection devices, treating them as a particular case of pulsed power devices. Thus both the most intriguing applications and reliability problems in case of the discrete and the integrated components are covered in this book.

Surface acoustic waves (SAWs) demonstrate simplicity of their excitation and receipt, as well as their availability to all propagation ways of signal branching and processing. SAW devices are divided into several main classes: filters for signal processing at intermediate frequencies, delay lines, resonators, filters with low losses for the input circuits of receiver, and antenna duplexers for the connected receivers. The SAW devices are not only able to conduct an effective signal processing, but also serve as a basis for multi-subsystems (matched filtering, signal processing, real-time Fourier transform processors, etc.). Additionally, SAW filters help scientists to realise the wide variety of frequency characteristics. Besides their unique electrical characteristics, SAW devices favorably differ from their analogs in small size, mechanical strength and high reliability, due to the quality of raw materials and their processing. The use of the photolithography and the achievements of group microelectronic technology in their production allow a researcher to achieve good reproducibility of parameters at relatively low cost. In addition, currently SAW devices are widely used in various sensors based on the SAW radio frequency identification. This book presents an attempt to generalise a multi-year experience on R&D of SAW devices. It develops original approaches directed at discovering solutions of technical problems, as development of various SAW devices are patented in Russia. Moreover, the book presents some experimental and theoretical research results.
Geolocation is a process that utilizes senors to pick up enemy emissions and locate electronic warfare (EW) targets. It is of particular interest among EW professionals because it allows them to use the enemy's own emissions to help set GPS coordinates and accurately pinpoint a target for attack. This book authoritative book is invaluable to EW engineers because it describes the mathematical development underlying current and classical methods of geolocating electronic systems that are emitting. Supported with over 620 equations and more than 115 illustrations, the book provides practitioners with critical information on a variety of geolocation algorithms and techniques. Engineers gain an in-depth understanding of key target location methods that they can effectively apply to their work in the field.
Combining technology, device design and simulation, and applications, this book is the first to deal with the design and optimization of transistors made from strained layers. Topics include background theory of the HBT, device simulation that predicts the optimum HBT device structure for a particular application, compact SiGe-HBT models for RF applications and the SPICE parameter extraction, and the enhancement of the high-frequency performance of HFETs using MOSFET or MODFET structures. The book also covers the design and application of optoelectronic devices and assesses how SiGe technology competes with other alternative technologies in the RF wireless communications marketplace.
