On the Reliability of Micro-Electronic Devices: An Introductory Lecture on Negative Bias Temperature Instability
Online Presentations | 28 Sep 2005 | Contributor(s):: Muhammad A. Alam
In 1930s Bell Labs scientists chose to focus on Siand Ge, rather than better known semiconductors like Ag2S and Cu2S, mostly because of their reliable performance. Their choice was rewarded with the invention of bipolar transistors several years later. In 1960s, scientists at Fairchild worked...

Modeling and Simulation of Sub-Micron Thermal Transport
Online Presentations | 26 Sep 2005 | Contributor(s):: Jayathi Murthy
In recent years, there has been increasing interest in understanding thermal phenomena at the sub-micron scale. Applications include the thermal performance of microelectronic devices, thermo-electric energy conversion, ultra-fast laser machining and many others. It is now accepted that Fourier's...

Moore's Law Forever?
Online Presentations | 13 Jul 2005 | Contributor(s):: Mark Lundstrom
This talk covers the big technological changes in the 20th and 21st century that were correctly predicted by Gordon Moore in 1965. Moore's Law states that the number of transistors on a silicon chip doubles every technology generation. In 1960s terms that meant every 12 months and currently...

Nanoelectronics: The New Frontier?
Online Presentations | 18 Apr 2005 | Contributor(s):: Mark Lundstrom
After forty years of advances in integrated circuit technology, microelectronics is undergoing a transformation to nanoelectronics. Modern day MOSFETs now have channel lengths of only 50 nm, and billion transistor logic chips have arrived. Moore’s Law continues, but the end of MOSFET scaling is...

Transistors
Online Presentations | 04 Aug 2004 | Contributor(s):: Mark Lundstrom
The transistor is the basic element of electronic systems. The integrated circuits inside today's personal computers, cell phones, PDA's, etc., contain hundreds of millions of transistors on a chip of silicon about 2 cm on a side. Each technology generation, engineers shrink the size of...

Self-Heating and Scaling of Silicon Nano-Transistors
Online Presentations | 05 Aug 2004 | Contributor(s):: Eric Pop
The most often cited technological roadblock of nanoscale electronics is the "power problem," i.e. power densities and device temperatures reaching levels that will prevent their reliable operation. Technology roadmap (ITRS) requirements are expected to lead to more heat dissipation problems,...

Exponential Challenges, Exponential Rewards - The Future of Moore's Law
Online Presentations | 14 Dec 2004 | Contributor(s):: Shekhar Borkar
Three exponentials have been the foundation of today's electronics, which are often taken for granted—namely transistor density, performance, and energy. Moore's Law captures the impact of these exponentials. Exponentially increasing transistor integration capacity, and...

Faster Materials versus Nanoscaled Si and SiGe: A Fork in the Roadmap?
Online Presentations | 20 Apr 2004 | Contributor(s):: Jerry M. Woodall
Strained Si and SiGe MOSFET technologies face fundamental limits towards the end of this decade when the technology roadmap calls for gate dimensions of 45 nm headed for 22 nm. This fact, and difficulties in developing a suitable high-K dielectric, have stimulated the search for alternatives to...

Nanoelectronics and the Future of Microelectronics
Online Presentations | 22 Aug 2002 | Contributor(s):: Mark Lundstrom
Progress in silicon technology continues to outpace the historic pace of Moore's Law, but the end of device scaling now seems to be only 10-15 years away. As a result, there is intense interest in new, molecular-scale devices that might complement a basic silicon platform by providing it...

Quantum-dot Cellular Automata
Online Presentations | 24 Nov 2003 | Contributor(s):: Craig S. Lent
The multiple challenges presented by the problem of scaling transistor sizes are all related to the fact that transistors encode binary information by the state of a current switch. What is required is a new paradigm, still capable of providing general purpose digital computation, but which can...
