Abstract:This paper presents two case studies, based on 32nm Silicon-On-Insulator (SOI) and 28nm bulk Si technology, on finding the root cause of nanometer scale short failures using Passive Voltage Contrast (PVC), Active Voltage Contrast (AVC) and Transmission Electron Microscopy (TEM). PVC/AVC is used as precision localization technique that is critical for a successful FA-TEM analysis. Combining planar TEM sample preparation and high sensitivity Energy Dispersive Spectroscopy (EDS) mapping, a small residual filament… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
