Dynamic compact thermal models with multiple power sources: application to an ultrathin chip stacking technology (2005)

Palacín Roca, Jordi, Salleras, Marc, Samitier I Martí, Josep, Marco Colás, Santiago

Whereas numerical modeling using finite-element methods (FEM) can provide transient temperature distribution in the component with enough accuracy, it is of the most importance the development of...

On-line event detection by recursive Dynamic Principal Component Analysis and gas sensor arrays under drift conditions (2003)

Perera I Lluna, Alexandre, Papamichail, Niko, Barsan, Nicolae, Weimar, Udo, Marco Colás, Santiago

Leakage detection is an important issue in many chemical sensing applications. Leakage detection hy thresholds suffers from important drawbacks when sensors have serious drifts or they are affected...

Thermal modeling and management in ultrathin chip stack technology (2002)

Pinel, Stèphane, Marty, Antoine, Tasselli, Josiane, Bailbe, Jean-Pierre, Beyne, Eric, Van Hoof, Rita, ...

This paper presents a thermal modeling for power management of a new three-dimensional (3-D) thinned dies stacking process. Besides the high concentration of power dissipating sources, which is the...

Suboptimal filtering and nonlinear time scale transformation for the analysis of multiexponential decays (2001)

Palacín Roca, Jordi, Marco Colás, Santiago, Samitier I Martí, Josep

Multiexponential decays may contain time-constants differing in several orders of magnitudes. In such cases, uniform sampling results in very long records featuring a high degree of oversampling at...

Improved multiexponential transient spectroscopy by iterative deconvolution (2001)

Marco Colás, Santiago, Palacín Roca, Jordi, Samitier I Martí, Josep

The analysis of multiexponential decays is challenging because of their complex nature. When analyzing these signals, not only the parameters, but also the orders of the models, have to be estimated....

Residual thermomechanical stresses in thinned-chip assemblies (2000)

Leseduarte Cuevas, Sergio, Marco Colás, Santiago, Beyne, Eric, Van Hoof, Rita, Marty, Antoine, Pinel, Stèphane, ...

A new technology for the three-dimensional (3-D) stacking of very thin chips on a substrate is currently under development within the ultrathin chip stacking (UTCS) Esprit Project 24910. In this...

A time-domain method for the analysis of thermal impedance response preserving the convolution form (1999)

Carmona, Manuel, Marco Colás, Santiago, Palacín Roca, Jordi, Samitier I Martí, Josep

The study of the thermal behavior of complex packages as multichip modules (MCM¿s) is usually carried out by measuring the so-called thermal impedance response, that is: the transient temperature...

Gas identification with tin oxide sensor array and self-organizing maps: adaptive correction of sensor drifts (1998)

Marco Colás, Santiago, Ortega Mansilla, Arturo, Pardo Martínez, Antonio, Samitier I Martí, Josep

Low-cost tin oxide gas sensors are inherently nonspecific. In addition, they have several undesirable characteristics such as slow response, nonlinearities, and long-term drifts. This paper shows...

Nonlinear inverse dynamic models of gas sensing systems based on chemical sensor arrays for quantitative measurements (1998)

Pardo Martínez, Antonio, Marco Colás, Santiago, Samitier I Martí, Josep

Gas sensing systems based on low-cost chemical sensor arrays are gaining interest for the analysis of multicomponent gas mixtures. These sensors show different problems, e.g., nonlinearities and slow...
