Book Description
Integrated temperature sensors play an important role in enhancing the performance of on-chip power and thermal management systems in today's highly-integrated system-on-chip (SoC) platforms, such as microprocessors. Accurate on-chip temperature measurement is essential to maximize the performance and reliability of these SoCs. However, due to non-uniform power consumption by different functional blocks, microprocessors have fairly large thermal gradient (and variation) across their chips. In the case of multi-core microprocessors for example, there are task-specific thermal gradients across different cores on the same die. As a result, multiple temperature sensors are needed to measure the temperature profile at all relevant coordinates of the chip. Subsequently, the results of the temperature measurements are used to take corrective measures to enhance the performance, or save the SoC from catastrophic over-heating situations which can cause permanent damage. Furthermore, in a large multi-core microprocessor, it is also imperative to continuously monitor potential hot-spots that are prone to thermal runaway. The locations of such hot spots depend on the operations and instruction the processor carries out at a given time. Due to practical limitations, it is an overkill to place a big size temperature sensor nearest to all possible hot spots. Thus, an ideal on-chip temperature sensor should have minimal area so that it can be placed non-invasively across the chip without drastically changing the chip floor plan. In addition, the power consumption of the sensors should be very low to reduce the power budget overhead of thermal monitoring system, and to minimize measurement inaccuracies due to self-heating. The objective of this research is to design an ultra-small size and ultra-low power temperature sensor such that it can be placed in the intimate proximity of all possible hot spots across the chip. The general idea is to use the leakage current of a reverse-bias p-n junction diode as an operand for temperature sensing. The tasks within this project are to examine the theoretical aspect of such sensors in both Silicon-On-Insulator (SOI), and bulk Complementary Metal-Oxide Semiconductor (CMOS) technologies, implement them in deep sub-micron technologies, and ultimately evaluate their performances, and compare them to existing solutions.

Book Description
This proceedings volume contains the contributions of the speakers who attended the NATO Advanced Research Workshop on "Perspectives, Science and Technologies for Novel Silicon on Insulator Devices" held at the Sanatorium Pushcha OLema, Kyiv, th Ukraine from It" to 15 October 1998. This meeting was the second NATO Silicon on Insulator (SOl) Workshop to be held in st the Ukraine where the first meeting (Gurzuf, Crimea, 1 to 4th November 1994) focussed upon the physical and technical problems to be addressed in order to exploit the advantages of incorporating SOl materials in device and sensor technologies. On this occasion emphasis was placed upon firstly, promoting the use of SOl substrates for a range of novel device and circuit applications and secondly, addressing the economic issues of incorporating SOl processing technologies and device technologies within the framework of the resources available within the laboratories and factories of the Newly Independent States (NIS). The primary goal of both workshops has been the breaking of the barriers that inhibit closer collaboration between scientists and engineers in the NATO countries and the NIS. Indeed, it was a pleasure for attendees at the first meeting to renew acquaintances and for the first time attendees to make new contacts and enjoy the warm hospitality offered by our hosts in Kyiv. An outcome was the forging of new links and concrete proposals for future collaborations.

Book Description
Silicon-on-Insulator Technology: Materials to VLSI, Third Edition, retraces the evolution of SOI materials, devices and circuits over a period of roughly twenty years. Twenty years of progress, research and development during which SOI material fabrication techniques have been born and abandoned, devices have been invented and forgotten, but, most importantly, twenty years during which SOI Technology has little by little proven it could outperform bulk silicon in every possible way. The turn of the century turned out to be a milestone for the semiconductor industry, as high-quality SOI wafers suddenly became available in large quantities. From then on, it took only a few years to witness the use of SOI technology in a wealth of applications ranging from audio amplifiers and wristwatches to 64-bit microprocessors. This book presents a complete and state-of-the-art review of SOI materials, devices and circuits. SOI fabrication and characterization techniques, SOI CMOS processing, and the physics of the SOI MOSFET receive an in-depth analysis.
