abstract: This study discusses MOS transistor models and their parameters required for VLSI simulation of MOS integrated circuits. It gives detailed presentation of model parameter determination for MOS models. Various models are developed ranging from simple to more sophisticated models that take into account new physical effects observed in submicron devices used in today's MOS VLSI technology. The assumptions used to arrive at the models are emphasized so that the accuracy of the model in describing the device characteristics are clearly understood. Understanding these models is essential when designing circuits for the state of the art MOS ICs. Since threshold voltage is the single most important MOSFET parameter, a full chapter is devoted to the development of the device threshold voltage model. Due to the importance of designing reliable circuits, the device reliability models, as applied for circuit simulations, are also covered. Since the device parameters vary due to inherent processing variations, how to arrive at worst case design parameters are also covered. Presentation of the material is such that even an undergraduate student, not well familiar with semiconductor device physics, can understand the intricacies of MOSFET modeling. The book serves as a technical source in the area of MOSFET modeling for state of the art MOSFET technology for both practicing device and circuit engineers, and engineering students interested in the area.

abstract: This book presents a unified view of MOSFET modeling, allowing the practitioner to view and interpret device phenomena concurrently using different modeling strategies, as opposed to gaining familiarity with the models in isolation. Secondly, while MOS devices are well covered in a number of text books, device physics do not get necessarily linked to model parameters which serve as an input in design phase, leaving a wide gap between device understanding and its use for optimal circuit performance. Further, being technology driven, models undergo evolution continuously. Yet from the projection of International Technology Roadmap for Semiconductors (ITRS) it is possible to identify the core physical concepts that will drive the evolution and trend that is likely to dominate the future. Therefore, the impact of quantum mechanical related phenomena has been given more prominent presence in the pedagogic approach of this book than is available in currently available texts.Uses a unified approach to coach students through the confusing array of MOSFET models One of the first books to relate MOS physics with device models to better prepare practitioners for real world design activities Helps fables designers bridge the gap with off site foundries Presents topics that will prepare readers for long term developments in the field Includes solutions in every chapter Can be tailored for use among students and professionals of many levels Comes with MATLAB code downloads for independent practice and advanced study Includes presentation slides with book figures for lecturer use

abstract: This paper presents a systematic methodology to develop statistical compact MOS models for advanced VLSI circuit simulation. Process variability in advanced CMOS technologies imposes a serious challenge for computer aided VLSI circuit design.

abstract: An alpha power law MOS model that includes the carrier velocity saturation effect, which becomes prominent in short channel MOSFETs, is introduced. The model is an extension of Shockley's square law MOS model in the saturation region. Since the model is simple, it can be used to handle MOSFET circuits analytically and can predict the circuit behavior in the submicrometer region. Using the model, closed form expressions for the delay, short circuit power, and transition voltage of CMOS inverters are derived. The delay expression includes input waveform slope effects and parasitic drain/source resistance effects and can be used in simulation and/or optimization CAD tools. It is found that the CMOS inverter delay becomes less sensitive to the input waveform slope and that short circuit dissipation increases as the carrier velocity saturation effect in short channel MOSFETs gets more severe.

abstract: The problem of achieving compact, high performance forced liquid cooling of planar integrated circuits has been investigated. The convective heat transfer coefficient h between the substrate and the coolant was found to be the primary impediment to achieving low thermal resistance. For laminar flow in confined channels, h scales inversely with channel width, making microscopic channels desirable. The coolant viscosity determines the minimum practical channel width. The use of high aspect ratio channels to increase surface area will, to an extent, further reduce thermal resistance. Based on these considerations, a new, very compact, water cooled integral heat sink for silicon integrated circuits has been designed and tested. At a power density of 790 W/cm2, a maximum substrate temperature rise of 71degC above the input water temperature was measured, in good agreement with theory. By allowing such high power densities, the heat sink may greatly enhance the feasibility of ultrahigh speed VLSI circuits.
