Method and system for determining the location of an open circuit in a semiconductor device using power modulation

摘要

A system and method for detecting a location of an open circuit is disclosed. The open circuit is in a circuit of semiconductor device. The semiconductor device has a surface. The method and system include supplying alternating power to the semiconductor device and sensing a time-varying signal that is related to the alternating power. The method and system also include determining where the signal is substantially changed.
