Summary:

Traditional time domain reflectometry (TDR) techniques employ time-based information to locate faults within packages with minimal references to internal structures. Here, we combine a novel and innovative technique, electro optical terahertz pulse reflectometry (EOTPR), with full 3D DUT modelling to quickly and non-destructively perform a feature-based analysis. We demonstrate fault isolation to an accuracy of 10µm or better with respect to device features in an advanced IC package.
