Nonlinear electrical conduction effects arising from local heating provide a means for detecting the presence of latent defects that are at risk of becoming open electronic circuits under stress. A special choice of ac drive current results in a dc intermodulation signal produced by nonlinear conduction, and offers several practical advantages over previous techniques involving ac harmonics. A key feature is the use of digital signal processing to provide speed, accuracy, and flexibility of measurement. A manufacturing screening system involving an automated prober integrated with the defect-detection tool is used to test high-performance glass-ceramic substrate interconnects used in advanced microelectronic packaging. © 2005 IBM.
