This paper shows how floating gate memory cells behavior during retention tests can be predicted relying on static stress tests. The electric high-field induced during write/erase cycles is mainly responsible for the retention time degradation because it creates intrinsic failures or traps in the EEPROM tunnel oxide.
In this paper, a correlation between the I-V slope at low fields and TDDB voltage acceleration is demonstrated for the first time, based on a wide range of data from 32 nm to 130 nm node hardware. The data supports the radicE model, which is based on electron fluence (leakage current) driven, Cu catalyzed, low-k dielectric breakdown. Using this correlation, a fast wafer level screen method was also...
In recent years, credit risk has played a key role in risk management issues. This paper accesses portfolio credit risk by using accelerated hazard rates. It explains how the concept of accelerated hazard rates, which used in reliability engineering, can be employed in finance to model credit risk, so as to link the default probabilities to the underlying macroeconomic and firm- specific factors.
We present a practical, systematical method for the evaluation of the soft error rate (SER) of microelectronic devices. Existing methodologies, practices and tools are integrated in a common approach while highlighting the need for specific data or tools. The showcased method is particularly adapted for evaluating the SER of very complex microelectronic devices by engineers confronted to increasingly...
Continuous scaling, necessary for enhanced performance and cost reduction, has pushed existing CMOS materials much closer to their intrinsic reliability limits, forcing reliability engineers to get a better understanding of circuit failure. This requires that designers will have to be very careful with phenomena such as high current densities or voltage overshoots. In addition to the reliability issues,...
This paper presents a structural health monitoring system for monitoring, with reduced visual impact, one historical building structure. The system is based on fiber Bragg gratings and comprises 19 displacement sensors and 5 temperature sensors. All the sensors were custom made according to the monitoring points' characteristics. The results obtained over the first year of monitoring are presented...
