A. Buck et al., TEMPERATURE AND THERMAL-CONDUCTIVITY MODES OF SCANNING PROBE MICROSCOPY FOR ELECTROMIGRATION STUDIES, Microelectronics and reliability, 37(10-11), 1997, pp. 1495-1498
We report here the use of Scanning Probe Microscopy (SPM) in two therm
al modes, as well as the usual topographical mode, for the study of sa
mples which have suffered electromigration damage. The temperature mod
e displays hot spots in the samples, under current bias, where there i
s a large void in the track and hence large local heating. The thermal
conductivity mode can detect large voids in the track even beneath a
passivation layer. (C) 1997 Elsevier Science Ltd.
