Thermal Cycling of 300 nm Buried Damascene Copper Interconnect Lines by Joule Heating

Read D.T., Geiss R.H., National Institute of Standards and Technology, US

We report tests of 300 nm wide damascene copper interconnect lines in silicon oxide dielectric to failure under high amplitude, low frequency alternating current. The cyclic minimum and maximum resistances were obtained from the measured [...]

Multiwalled carbon nanotube films as temperature nano-sensors

Di Bartolomeo A., Giubileo F., Sarno M., Altavilla C., Sannino D., Iemmo L., Mancusi D., Bobba F., Cucolo A.M., Ciambelli P., University of Salerno, IT

The understanding of the temperature dependence of the electric resistance of carbon nanotubes (CNTs) is a very important feature for the potential utilization as sensing element in temperature nano-sensors. The sensitivity and the time response [...]

Study on non-Freon air cooling system using water refrigerant

Sugawara A., Nakamikawa S., Kageyama M., Yamazaki S., Abe N., Itou T., Tsurumaki A., Kawasaki K., Niigata University, JP

This paper aims for construction of a small, clean air cooling system using a water refrigerant and examines it experimentally. We offer a basic report for realization of the non-Freon air-cooling system using only water [...]

Influence of Stress and Temperature on the Microstructure Stability of Nanocrystalline Materials

Rajgarhia R.K., Koh S-W., Spearot D., Saxena A., Selvam P., Tummala R., University of Arkansas, Fayetteville, US

Nanocrystalline materials have improved mechanical and electrical properties in comparison to their microcrystalline counterparts due to their reduced crystallite or grain size. Loss of these unique properties due to grain growth under the affect of [...]

PTAT voltage generator based on an MOS voltage divider

Rossi C., Galup-Montoro C., Schneider M.C., Universidad de la Republica, UY

Little has been published on the use of charge-based compact models as tools for variable operating temperature design. We analyzed an MOS voltage divider applying the ACM model obtaining an equation relating the voltage at [...]

A Temperature-related Homogenization Technique for Nanoscale Continuum Approximation

Xiao S.P., Yang W.X., The University of Iowa, US

A new homogenization technique, the temperature-related Cauchy-Born (TCB) rule, is proposed in this paper with the consideration of the free energy instead of the potential energy. The TCB rule is verified via stress analyses of [...]

Studies of Nanotube-based Co-axial and Resonant Oscillators

Xiao S.P., Andersen D., Hou W.Y., The University of Iowa, US

In this paper, we first investigate mechanisms of nanotube-based co-axial oscillators, shown in Figure 1, based on molecular dynamics simulation. We mainly study the interlayer friction between the outer tube and the inner tube when [...]

Technique for Time and Frequency Dependent Solutions of the Diffusion Equation: Application to temperature of nanoscale devices

Forbes L., Wanalertlak W., Louie M.Y., Oregon State University, US

Typical CMOS device currents have remained around 1mA/um while devices have scaled down. The projection into the 2010 time frame is 0.01um or 10nm dimensions with 0.5V power supplies which results for a minimum dimension [...]

A Distributed Compact Model for High-Density, On-Chip Trench Capacitors in High-Frequency Applications

Shastri S., Wu Y., Cai W.Z., Grivna G., ON Semiconductor, US

In this paper we describe for the first time a distributed model for the trench capacitor, which includes process parameters that may be extracted from the low-frequency measurement of one or two capacitor geometries. The [...]
