Abstract
According to an example embodiment of the present invention, a defect detection approach involves detecting the existence of defects in an integrated circuit as a function of at least one applied energy source. In response to energy that is applied to the integrated circuit, response signals are detected. A parameter including information such as amplitude, frequency, phase, or a spectrum is developed for a reference integrated circuit device and then compared to the detected response signal. The deviation in the response and reference signals, and the type of energy source used, are correlated to a particular defect in the device.
