Download or read book Latchup written by Steven H. Voldman and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in latchup is being renewed with the evolution of complimentary metal-oxide semiconductor (CMOS) technology, metal-oxide-semiconductor field-effect transistor (MOSFET) scaling, and high-level system-on-chip (SOC) integration. Clear methodologies that grant protection from latchup, with insight into the physics, technology and circuit issues involved, are in increasing demand. This book describes CMOS and BiCMOS semiconductor technology and their sensitivity to present day latchup phenomena, from basic over-voltage and over-current conditions, single event latchup (SEL) and cable discharge events (CDE), to latchup domino phenomena. It contains chapters focusing on bipolar physics, latchup theory, latchup and guard ring characterization structures, characterization testing, product level test systems, product level testing and experimental results. Discussions on state-of-the-art semiconductor processes, design layout, and circuit level and system level latchup solutions are also included, as well as: latchup semiconductor process solutions for both CMOS to BiCMOS, such as shallow trench, deep trench, retrograde wells, connecting implants, sub-collectors, heavily-doped buried layers, and buried grids – from single- to triple-well CMOS; practical latchup design methods, automated and bench-level latchup testing methods and techniques, latchup theory of logarithm resistance space, generalized alpha (a) space, beta (b) space, new latchup design methods– connecting the theoretical to the practical analysis, and; examples of latchup computer aided design (CAD) methodologies, from design rule checking (DRC) and logical-to-physical design, to new latchup CAD methodologies that address latchup for internal and external latchup on a local as well as global design level. Latchup acts as a companion text to the author’s series of books on ESD (electrostatic discharge) protection, serving as an invaluable reference for the professional semiconductor chip and system-level ESD engineer. Semiconductor device, process and circuit designers, and quality, reliability and failure analysis engineers will find it informative on the issues that confront modern CMOS technology. Practitioners in the automotive and aerospace industries will also find it useful. In addition, its academic treatment will appeal to both senior and graduate students with interests in semiconductor process, device physics, computer aided design and design integration.

Book excerpt: The potential for latch-up, a pnpn self-sustaining low impedance state, is inherent in standard bulk CMOS-integrated circuit structures. Under normal bias, the parasitic SCR is in its blocking state but, if subjected to a large voltage spike or if exposed to an ionizing environment, triggering may occur. This may result in device burn-out or loss of state. The problem has been extensively studied for space and weapons applications. Prevention of latch-up has been achieved in conservative design (approx. 9 .mu.m p-well depths) by the use of minority lifetime control methods such as gold doping and neutron irradiation and by modifying the base transport factor with buried layers. The push toward VLSI densities will enhance parasitic action sufficiently so that the problem will become of more universal concern. The paper will surveys latch-up control methods presently employed for weapons and space applications on present (approx. 9 .mu.m p-well) CMOS and indicates the extent of their applicability to VLSI designs.

Download or read book Latchup in CMOS Technology written by R.R. Troutman and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why a book on Iatchup? Latchup has been, and continues to be, a potentially serious CMOS reliability concern. This concern is becoming more widespread with the ascendency of CMOS as the dominant VLSI technology, particularly as parasitic bipolar characteristics continue to improve at ever smaller dimensions on silicon wafers with ever lower defect densities. Although many successful parts have been marketed, latchup solutions have often been ad hoc. Although latchup avoidance techniques have been previously itemized, there has been little quantitative evaluation of prior latchup fixes. What is needed is a more general, more systematic treatment of the latchup problem. Because of the wide variety of CMOS technologies and the long term interest in latchup, some overall guiding principles are needed. Appreciating the variety of possible triggering mechanisms is key to a real understanding of latchup. This work reviews the origin of each and its effect on the parasitic structure. Each triggering mechanism is classified according to a new taxonomy.

Available in PDF, EPUB and Kindle. Book excerpt: VLSI Electronics Microstructure Science, Volume 18: Advanced MOS Device Physics explores several device physics topics related to metal oxide semiconductor (MOS) technology. The emphasis is on physical description, modeling, and technological implications rather than on the formal aspects of device theory. Special attention is paid to the reliability physics of small-geometry MOSFETs. Comprised of eight chapters, this volume begins with a general picture of MOS technology development from the device and processing points of view. The critical issue of hot-carrier effects is discussed, along with the device engineering aspects of this problem; the emerging low-temperature MOS technology; and the problem of latchup in scaled MOS circuits. Several device models that are suitable for use in circuit simulators are also described. The last chapter examines novel electron transport effects observed in ultra-small MOS structures. This book should prove useful to semiconductor engineers involved in different aspects of MOS technology development, as well as for researchers in this field and students of the corresponding disciplines.

This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of putting `systems on a chip' has been a difficult challenge that is only recently being met. Since the world is `analog', putting systems on a chip requires putting analog interfaces on the same chip as digital processing functions. Since some processing functions are accomplished more efficiently in analog circuitry, chips with a large amount of analog and digital circuitry are being designed. Whether a small amount of analog circuitry is combined with varying amounts of digital circuitry or the other way around, the problem encountered in marrying analog and digital circuitry are the same but with different scope. Some of the most prevalent problems are chip/package capacitive and inductive coupling, ringing on the RLC tuned circuits that form the chip/package power supply rails and off-chip drivers and receivers, coupling between circuits through the chip substrate bulk, and radiated emissions from the chip/package interconnects. To aggravate the problems of designers who have to deal with the complexity of mixed-signal coupling there is a lack of verification techniques to simulate the problem. In addition to considering RLC models for the various chip/package/board level parasitics, mixed-signal circuit designers must also model coupling through the common substrate when simulating ICs to obtain an accurate estimate of coupled noise in their designs. Unfortunately, accurate simulation of substrate coupling has only recently begun to receive attention, and techniques for the same are not widely known. Simulation Techniques and Solutions for Mixed-Signal Coupling in Integrated Circuits addresses two major issues of the mixed-signal coupling problem -- how to simulate it and how to overcome it. It identifies some of the problems that will be encountered, gives examples of actual hardware experiences, offers simulation techniques, and suggests possible solutions. Readers of this book should come away with a clear directive to simulate their design for interactions prior to building the design, versus a `build it and see' mentality.
