Improve Failure Analysis Success Rate With Layout-Aware Diagnosis


In this whitepaper, we explore how a layout-aware diagnosis is a powerful tool for both failure analysis engineers, who find the root cause of a particular failing die, and for yield engineers, who need sets of diagnosis data to find the systematic yield limiters across the life of the product. Logic-based scan test diagnosis is an established software-based methodology for finding the defec... » read more

Root Cause Deconvolution


Scan logic diagnosis turns failing test cycles into valuable data and is an established method for digital semiconductor defect localization. The advent of layout-aware scan diagnosis represented a dramatic advance in diagnosis technology because it reduces suspect area by up to 85% and identifies physical net segments rather than entire logic nets [1-3]. The defect classifications provided by ... » read more
