Book excerpt: One of the main problems encountered when scaling down is the hot carrier induced degradation of MOSFETs. This problem has been studied intensively during the past decade, under both static and dynamic stress conditions. In this period it has evolved from a more or less academic research topic to one of the most stringent constraints guaranteeing the lifetime of sub-micron devices. New drain engineering technique leads to the extensive usage of lateral doped drain structures. In these devices the peak of the lateral field is lowered by reducing the doping concentration near the drain and by providing a smooth junction transition instead of an abrupt one. Therefore, the amount of hot carrier generation for a given supply voltage and the influence of a certain physical damage on the electrical characteristics is decreased dramatically. A complete understanding of the hot carrier degradation problem in sub-micron 0.25um LD MOSFETs is presented in this work. First we discuss the degradation mechanisms observed under, for circuit operation, somewhat artificial but well-controlled uniform-substrate hot electron and substrate hot-hole injection conditions. Then the more realistic case of static channel hot carrier degradation is treated, and some important process-related effects are illustrated, followed by the behavior under the most relevant case for real operation, namely dynamic degradation. An Accurate and practical parameter extraction is used to obtain the LD MOSFETs model parameters, with the experiment verification. Good agreement between the model simulation and experiment is achieved. The gate charge transfer performance is examined to demonstrate the hot carrier effect. Furthermore, In order to understand the dynamic stress on the LD MOSFET and its effect on RF circuit, the hot-carrier injection experiment in which dynamic stress with different duty cycle applied to a LD MOS transistor is presented. A Class-C power amplifier is used to as an example to demonstrate the effect of dynamic stress on RF circuit performance. Finally, the strategy for improving hot carrier reliability and a forecast of the hot carrier reliability problem for nano-technologies are discussed. The main contribution of this work is, it systemically research the hot carrier reliability issue on the sub-micron lateral doped drain MOSFETs, which is induced by static and dynamic voltage stress; The stress condition mimics the typical application scenarios of LD MOSFET. Model parameters extraction technique is introduced with the aid of the current device modeling tools, the performance degradation model can be easily implement into the existing computer-aided tools. Therefore, circuit performance degradation can be accurately estimated in the design stage. CMOS technologies are constantly scaled down. The production on 65 nm is on the market. With the reduction in geometries, the devices become more vulnerable to hot carrier injection (HCI). HCI reliability is a must for designs implemented with new processes. Reliability simulation needs to be implemented in PDK libraries located on the modeling stage. The use of professional tools is a prerequisite to develop accurate device models, from DC to GHz, including noise modeling and nonlinear HF effects, within a reasonable time. Designers need to learn to design for reliability and they should be educated on additional reliability analyses. The value is the reduction of failure and redesign costs.

Available in PDF, EPUB and Kindle. Book excerpt: The exploding number of uses for ultrafast, ultrasmall integrated circuits has increased the importance of hot-carrier effects in manufacturing as well as for other technological applications. They are rapidly movingout of the research lab and into the real world. This book is derived from Dr. Takedas book in Japanese, Hot-Carrier Effects, (published in 1987 by Nikkei Business Publishers). However, the new book is much more than a translation. Takedas original work was a starting point for developing this much more complete and fundamental text on this increasingly important topic. The new work encompasses not only all the latest research and discoveries made in the fast-paced area of hot carriers, but also includes the basics of MOS devices, and the practical considerations related to hot carriers. Chapter one itself is a comprehensive review of MOS device physics which allows a reader with little background in MOS devices to pick up a sufficient amount of information to be able to follow the rest of the book The book is written to allow the reader to learn about MOS Device Reliability in a relatively short amount of time, making the texts detailed treatment of hot-carrier effects especially useful and instructive to both researchers and others with varyingamounts of experience in the field The logical organization of the book begins by discussing known principles, then progresses to empirical information and, finally, to practical solutions Provides the most complete review of device degradation mechanisms as well as drain engineering methods Contains the most extensive reference list on the subject

This book was released on 2012-12-06 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: As device dimensions decrease, hot-carrier effects, which are due mainly to the presence of a high electric field inside the device, are becoming a major design concern. On the one hand, the detrimental effects-such as transconductance degradation and threshold shift-need to be minimized or, if possible, avoided altogether. On the other hand, performance such as the programming efficiency of nonvolatile memories or the carrier velocity inside the devices-need to be maintained or improved through the use of submicron technologies, even in the presence of a reduced power supply. As a result, one of the major challenges facing MOS design engineers today is to harness the hot-carrier effects so that, without sacrificing product performance, degradation can be kept to a minimum and a reli able design obtained. To accomplish this, the physical mechanisms re sponsible for the degradations should first be experimentally identified and characterized. With adequate models thus obtained, steps can be taken to optimize the design, so that an adequate level of quality assur ance in device or circuit performance can be achieved. This book ad dresses these hot-carrier design issues for MOS devices and circuits, and is used primarily as a professional guide for process development engi neers, device engineers, and circuit designers who are interested in the latest developments in hot-carrier degradation modeling and hot-carrier reliability design techniques. It may also be considered as a reference book for graduate students who have some research interests in this excit ing, yet sometime controversial, field.

This book was released on 2012-07 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current problems in electronics for manufacturers or users are to determine the lifetime and estimate the reliability of device or system. As well improve their performance and quality. This book presents a synthesis of Hot-Electron effects on power RF LDMOS performances, after accelerated ageing tests. This can modify and degrade transistor physical and electrical behaviour. The temperature can limit the lifetime of semiconductors and plays an essential part in the degradation mechanisms. An electric characterization (IC-CAP) has been made, and a thermoelectric model ADS has been implemented. This is used as the reliability tool (parameters extraction) in order to quantify the parameter shift. We have pointed out the relation between the ageing tests and the hot carrier degradation in RF LDMOS, and its effect on the electric performances. To understanding of the degradation physical phenomena brought into play in the structure, we used a physical simulation 2-D (Atlas) to con rm these phenomena. Finally, the work demonstrates that the degradation mechanism of power RF LDMOS is the hot carrier injection phenomenon in the already existing oxide traps and/or in the Si/SiO2 interface."

Available in PDF, EPUB and Kindle. Book excerpt: The book summarizes and compares recent advancements in the development of novel lateral power transistors (LDMOS devices) for integrated circuits in power electronic applications. In its first part, the book motivates the necessity for lateral power transistors by a top-down approach: First, it presents typical energy conversion applications in modern industrial, automotive and consumer electronics. Next, it introduces common circuit topologies suitable for these applications, and discusses the feasibility for monolithic integration. Finally, the combination of power and logic functionality on a single chip is motivated and the requirements and limitations for the power semiconductor devices are deduced. The second part describes the evolution of lateral power transistors over the past decades from the simple pin-type concept to double-acting RESURF topologies. It describes the principle of operation for these LDMOS devices and discusses limitations of lateral power devices. Moreover, figures-of-merit are presented which can be used to evaluate the performance of the novel lateral power transistors described in this book with respect to the LDMOS devices. In the last part, [..] the fundamental physical concepts including charge compensation and trench gate topologies are discussed. Also, the status of research in LDMOS devices on silicon carbide is presented. Advantages and drawbacks for each of these integration approaches are summarized, and the feasibility with respect to power electronic applications is evaluated.
