© 2002 IEEE. CMOS chips having high leakage are observed to have high burn-in fallout rate. IDDQ testing has been considered as an alternative to burn-in. However, increased subthreshold leakage current in deep submicron technologies limits the use of IDDQ testing in its present form. In this work, a statistical outlier rejection technique known as the median of absolute deviations (MAD) is evaluated as a means to screen early failures using IDDQ data. MAD is compared with delta IDDQ and current signature methods. The results of the analysis of the SEMATECH data are presented.
