We have developed an EB/FIB integrated test system, where the in-situ verif
ication of repair by waveform measurement in the FIB system is carried out.
We discuss the characteristics of the waveform measurement by the FIB syst
em. From experiments, the time resolution, the voltage sensitivity, and the
damage control criterion are derived. We apply the system to a faulty VLSI
chip in order to show its validity. (C) 2001 Elsevier Science Ltd. All rig
