A new experimental set-up dedicated to front side and backside picosecond O
BIC testing is presented. Applications for fundamental study of integrated
circuits are presented. Front side and backside OBIC images of an analog in
tegrated circuit show the potentiality and the suitability of this new equi
pment an methodology for laser testing of VLSI circuits. (C) 2001 Elsevier
