Book Synopsis Hf-Based High-k Dielectrics by : Young-Hee Kim
Download or read book Hf-Based High-k Dielectrics written by Young-Hee Kim and published by Morgan & Claypool Publishers. This book was released on 2006-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, the reliability of HfO2 (hafnium oxide) with poly gate and dual metal gate electrode (Ru–Ta alloy, Ru) was investigated. Hard breakdown and soft breakdown, particularly the Weibull slopes, were studied under constant voltage stress. Dynamic stressing has also been used. It was found that the combination of trapping and detrapping contributed to the enhancement of the projected lifetime. The results from the polarity dependence studies showed that the substrate injection exhibited a shorter projected lifetime and worse soft breakdown behavior, compared to the gate injection. The origin of soft breakdown (first breakdown) was studied and the results suggested that the soft breakdown may be due to one layer breakdown in the bilayer structure (HfO2/SiO2: 4 nm/4 nm). Low Weibull slope was in part attributed to the lower barrier height of HfO2 at the interface layer. Interface layer optimization was conducted in terms of mobility, swing, and short channel effect using deep submicron MOSFET devices.

Book Synopsis Defects in HIgh-k Gate Dielectric Stacks by : Evgeni Gusev
Download or read book Defects in HIgh-k Gate Dielectric Stacks written by Evgeni Gusev and published by Springer Science & Business Media. This book was released on 2006-01-27 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Materials Fundamentals of Gate Dielectrics by : Alexander A. Demkov
Download or read book Materials Fundamentals of Gate Dielectrics written by Alexander A. Demkov and published by Springer Science & Business Media. This book was released on 2006-05-24 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents materials fundamentals of novel gate dielectrics that are being introduced into semiconductor manufacturing to ensure the continuous scalling of the CMOS devices. This is a very fast evolving field of research so we choose to focus on the basic understanding of the structure, thermodunamics, and electronic properties of these materials that determine their performance in device applications. Most of these materials are transition metal oxides. Ironically, the d-orbitals responsible for the high dielectric constant cause sever integration difficulties thus intrinsically limiting high-k dielectrics. Though new in the electronics industry many of these materials are wel known in the field of ceramics, and we describe this unique connection. The complexity of the structure-property relations in TM oxides makes the use of the state of the art first-principles calculations necessary. Several chapters give a detailed description of the modern theory of polarization, and heterojunction band discontinuity within the framework of the density functional theory. Experimental methods include oxide melt solution calorimetry and differential scanning calorimetry, Raman scattering and other optical characterization techniques, transmission electron microscopy, and x-ray photoelectron spectroscopy. Many of the problems encounterd in the world of CMOS are also relvant for other semiconductors such as GaAs. A comprehensive review of recent developments in this field is thus also given. The book should be of interest to those actively engaged in the gate dielectric research, and to graduate students in Materials Science, Materials Physics, Materials Chemistry, and Electrical Engineering.

Download or read book High-k Gate Dielectric Materials written by Niladri Pratap Maity and published by CRC Press. This book was released on 2020-12-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores and addresses the challenges of high-k gate dielectric materials, one of the major concerns in the evolving semiconductor industry and the International Technology Roadmap for Semiconductors (ITRS). The application of high-k gate dielectric materials is a promising strategy that allows further miniaturization of microelectronic components. This book presents a broad review of SiO2 materials, including a brief historical note of Moore’s law, followed by reliability issues of the SiO2 based MOS transistor. It goes on to discuss the transition of gate dielectrics with an EOT ~ 1 nm and a selection of high-k materials. A review of the various deposition techniques of different high-k films is also discussed. High-k dielectrics theories (quantum tunneling effects and interface engineering theory) and applications of different novel MOSFET structures, like tunneling FET, are also covered in this book. The volume also looks at the important issues in the future of CMOS technology and presents an analysis of interface charge densities with the high-k material tantalum pentoxide. The issue of CMOS VLSI technology with the high-k gate dielectric materials is covered as is the advanced MOSFET structure, with its working structure and modeling. This timely volume will prove to be a valuable resource on both the fundamentals and the successful integration of high-k dielectric materials in future IC technology.
